The branches are a few centimetres apart and can grow to a height of 30 centimetres (12 in). These different biological activities provide a glimpse of biomedical innovations for the future. Caulerpa racemosa on Interactive Guide to Caribbean Diving, the Marine Species Identification Portal: Technical fact sheet. Abstract A novel water-soluble polysaccharide (named CRVP-1) was successfully obtained from Caulerpa racemosa var peltata by hot-water extraction, ethanol precipitation, and column chromatography. Chlorophyta are a paraphyletic group. Two sites of P. oceanica covered with the densest canopy of the C. racemosa were chosen: the dead mats of mucronata L.N.de Senerpont Domis, 2003; Caulerpa racemosa var. It utilizes, emptying, all the cytoplasm to create male and female gametes that merge at sea creating swimming spherical zygotes, a “green cloud”, that reduces the visibility to less one metre when, as often occurs, the reproduction takes place in mass. Furthermore, it may reduce the arterial hypertension and displays antibacterial and anti-fungal properties. The plants are monoecious with male and female gametes being produced by the same plant and liberated into the water column where they unite to give spherical zygotes. This species resembles another native Hawaiian Caulerpa species, C. taxifolia. In addition to the nutritional qualities of C. racemosa, it also has anti bacterial and anti-oxidant properties but these characteristics are not yet fully explored [1]. Mass spawning is advantageous to the plant in increasing the chances of fertilisation. The sea breams Boops boops and Sarpa salpa were found to feed on the algae, as did the sea urchins Paracentrotus lividus and Sphaerechinus granularis. Caulerpa racemosa (Forsskal) J. Agardh Taxonomic Serial No. They are shiny green, grape like plants mainly used as vegetables. It is known as C. racemosa var. tomentosoides, Caulerpa taxifolia, Undaria pinnatifida, Asparagopsis armata and Grateloupia doryphora, while Sargassum muticum ranked eight and Caulerpa racemosa ten. The structure of CRVP-1 was characterized … When pieces of the plant get broken off they develop into new plants. The first one, in fact, formed only by cloned specimens, has never reproduced sexually in the Mediterranean and starting from 2004 is losing ground due to a molecular degeneration, whilst this last reproduces also sexually in our seas adapting always better to the new environments. Chlorophyta are commonly known as green algae. Extracts of C. racemosa are already tested to reduce different types of cancer [3] but also to fight against multi-drug resistant uropathogens (as K. Pneumoniae and P. aeruginosa). An endless process even if in the Mediterranean, where it has arrived stuck to the keel of the ships coming from the Red Sea, there is a moment of winter rest. Abstract A novel water-soluble polysaccharide (named CRVP-1) was successfully obtained from Caulerpa racemosa var peltata by hot-water extraction, ethanol precipitation, and column chromatography. [3] Like other members of the order Bryopsidales, each C. racemosa plant consists of a single enormous cell with a large number of nuclei. peltata has disk-like appendages attached to the branchlets and C. racemosa var. This plant can be weedy or invasive according to the authoritative sources noted below.This plant may be known by one or more common names in … It is commonly known as sea grapes (along with the related Caulerpa lentillifera) and is found in many areas of shallow sea around the world. Like the Caulerpa taxifolia that while breaking releases a venomous latex containing caleurpin, also the Caulerpa racemosa utilizes, though in minor extent, this venom that seems harmless for the man but is harmful for many marine herbivorous invertebrates such as the Motted Sea Hare (Aplysia fasciata). When all categories (excluding salinity and temperature) were summed, the top five risk species, all invasive, were, in descending order, C. fragile spp. killer algae. Physiological and Structural Characteristics of Three Varieties of Caulerpa racemosa (Försskal) J. Agardh. It spread widely, invading much of the Mediterranean Sea and becoming more widespread than the invasive species, Caulerpa taxifolia. Many spherical or ovate side-shoots branch off these and give the seaweed its name of sea grapes. They are rich in fiber, proteins, minerals (calcium and magnesium), folic acid, ascorbic acid, vitamin A, and vitamin B1 while also being low in fat. In 1926 a new form of the alga was reported off Tunisia, possibly an immigrant from the Red Sea, and this later spread to much of the eastern Mediterranean Sea. It has created waves in the international food market because of its high nutritional value. cylindracea has a slender thallus, fixed to the substratum by means of thin rootlike rhizoids 1-10 (to 20) mm long and 0.3-0.8 (to 1.0) mm in diameter, that are closely arranged along the stolon. Many of them exhibit polymorphism, showing different growth forms in different habitats which makes them difficult to identify. Caulerpa racemosa (Forsskal) J. Agardh is a siphonaceous green alga exhibit­ ... that this environmental factor may influence the morphology of C. racemosa. Like the closely related Caulerpa lentillifera, C. racemosa is edible. Caulerpa taxifolia. uvifera (C.Agardh) Kützing, 1849; Fucus clavifer Turner, 1807; Fucus racemosus Forsskål, 1775; Fucus uvifer Turner, 1811. Grape Caulerpa is a prolific green macroalgae that looks great but can sometimes spread quickly. C. racemosa var. It is also eaten by local fishermen in Malaysia and Indonesia. Branches, feather-like, flattened, and upright, 3 - 10 cm high, rising from a creeping stolon (runner), 1 - 2 mm in diameter, anchored by rhizoids to the substrate. In 1990, a new, larger form with two vertical rows of branches on opposite sides of the stem was found off Libya. The Caulerpa racemosa grows, like all green algae, in rather shallow waters, with a predilection for the tropical and temperate climates. These protective characteristics of C. racemosa might be attributed to its remarkable antioxidant (total phenolics, total flavonoids, DPPH and ABTS radical scavenging, and reducing power) and Fe-chelation properties. [10] Similar mass spawnings take place in the Mediterranean Sea causing a cloud of green gametes to be released in the water approximately 14 minutes before sunrise. There are two distinct varieties, although it is unsure if they are separate species. These deter animals from consuming the plants. And, at least in the aquarium hobby, the genus name is also used as their common name. © MONACO NATURE ENCYCLOPEDIA | All rights reserved. There are about 75 species of Caulerpa. lycopodium was also sold as "Grape Caulerpa". Ceccherelli, G., L. Branchlets oppositely attached to midrib, flattened, slightly curved upwards, tapered at both base and tip, and constricted at point of attachment. It belongs to the genus of Caulerpa and the family of Caulerpaceae. peltata Frond: grape-like to disc-like (up to 5cm tall) Branchlets: mushroom shaped to flattened discs (3-4mm in diameter), can have both types of branchlets on one individual or just one type Toothed Margins Photo: Dr. John Huisman Photo: Susan Zaleski DESCRIPTION: Caulerpa is a genus of marine (salt water) algae that has a growth form with creeping rhizomes that produce tufts of colorless rhizoids (root-like structures) downward and photosynthetic branches upward. Morphological and photosynthetic performance were analyzed in species of the genus Caulerpa from an exposed coral reef and a sheltered reef lagoon. The arrangement and shape of the branches differ among the numerous varieties. Like Caulerpa taxifolia, Caulerpa racemosa colonizes all types of substrate such as rock, sand, mud and dead Posidonia meadows down to 60m depth and interferes with marine coastal biocenoses. Not palatable to fish. For a long time in the hobby, Caulerpa cupressoides var. C. racemosa sensu lato is highly variable in size and shape, with about a dozen varieties and forms. The thallus appears divided in a creeping stem with rhizoids, the “roots” of the algae that unlike the vascular or tracheophyte plants (Tracheophyta) do not absorb the nutrients but serve uniquely to fix on the bottom, and showy fronds, composed by a central rachis from which several grape or club-like ramuli emerge, forming a structure that can be up to 30 cm high. This species can be invasive from time to time. [3], In the Mediterranean, growth begins in April when new stolons develop and erect branches start growing, and continue till December, after which the plants decline and become dormant. Described for the first time in Australia, the Caulerpa racemosa (Forsskål) J.Agardh, 1873 is a green marine alga (Chlorophyta) belonging to the family of the Caulerpaceae, like the well known Caulerpa prolifera of the Mediterranean or the infamous Caulerpa taxifolia native to Australia, Central America and the African coasts. disticha V.J.Chapman, 1977; Caulerpa racemosa var. A study has been done on herbivores that graze on meadows of the invasive C. cylindracea in the north west of its range in the Mediterranean. [8] Mass spawnings sometimes take place in the Caribbean Sea and normally do so just before dawn. Morphological characters, such as distance between modules, number of modules, stolon branches and rhizoid clusters per centimeter of stolon, indicated a uniformity among species within a specific habitat. Dark green to light green. Midrib is slightly flattened, appearing oval in cross-section. Keywords: Antioxidants, Caulerpa racemosa (green macroalga), iron overload, Fe-chelation, oxidative stress, thalassemia therapy clavifera (Turner) Weber Bosse, 1898; Caulerpa racemosa var. The effect of C. racemosa incorporation on nutritional, physical, anti-oxidative and sensorial characteristics of biscuits was assessed. City of San Diego Law: Bans the possession, sale, and transport of all Caulerpa species within city limits (City of San Diego Ordinance 18967) Species Commonly Confused with Caulerpa The zygotes swim, at the most, for one hour and then fix on the bottom creating in the space of just 5 weeks, new plants. taxifolia, Caulerpa sertularioides, Caulerpa mexicana, Caulerpa ashmeadii, Caulerpa scalpelliformis, Caulerpa racemosa (and all varieties of C. racemosa), Caulerpa cu-pressoides, Caulerpa verticillata, and Caulerpa floridana. The chloroplasts containing chlorophyll are free to migrate from any part of the organism to another and there is a network of fibrous proteins that helps movement of organelles. Moreover, this monoecious species, as well as vegetatively, can also reproduce sexually. Some fish of the Mediterranean, such as the Salpa (Sarpa salpa), if there is nothing better, graze, breaking it in pieces, more willingly than the other and it is getting the upper hand everywhere. Caulerpa racemosa var. This is the species we offer. It is an edible species with known medicinal virtues, but carried by the keel of the ships, has invaded many temperate seas among which, from 1990, the Mediterranean where it reproduces also sexually unlike an earlier invader, the Caulerpia taxifolia, coming from the aquaria market and accidentally escaped from a pool © Giuseppe Mazza. [5] In America C. racemosa is found in shallow water in the Caribbean Sea, around Bermuda and along the eastern seaboard of America from Florida to Brazil. Underwater visibility can be reduced to less than one metre by the green cloud produced in the process. C. sertularioides is more delicate and t… Caulerpa is a genus of seaweeds in the family Caulerpaceae (among the green algae). macrophyso forms upright columns bearing grape-like spheres. Influence of sea grapes (Caulerpa racemosa) supplementation on physical, functional, and anti-oxidant properties of semisweet biscuits. Particular of the creeping stolon with fronds growing in madreporic environment © Giuseppe Mazza. We do not know yet how they can synchronize these “group weddings” that are not linked to the lunar cycles or the tide, but in Mediterranean and in the Caribbean often happen just before dawn. They are rich in fiber, proteins, minerals (calcium and magnesium), folic acid, ascorbic acid, vitamin A, and vitamin B1 while also being low in fat.[14]. The branches (called ramuli on seaweed and coral) can be sparse or dense. A species in the Mediterranean can have a stolon more than 3 metres (9.8 ft) long, with up to 200 fronds. Dispersal of, CS1 maint: multiple names: authors list (, Caulerpa racemosa (Forsskål) J.Agardh, 1873, On the identity and origin of the Mediterranean invasive, "Mass Spawning by Green Algae on Coral Reefs", Mass Spawning by Green Algae on Coral Reefs, Sexual reproduction of the invasive green alga, "Opportunities and challenges for developed, https://en.wikipedia.org/w/index.php?title=Caulerpa_racemosa&oldid=988870498, Creative Commons Attribution-ShareAlike License, This page was last edited on 15 November 2020, at 19:19. [6] Caulerpa taxifolia and Caulerpa racemosa shows the great influence of substratum on their spatial distribution with a high colonization of the dead matte of the seagrass Posidonia oceanica[12], Caulerpenyne content is lesser in Caulerpa racemosa than in the related and also invasive Lessepsian migrant Caulerpa taxifolia. The multi drug resistance is a major public health problem because by 2050 (World Health Organization WHO), 10 million people could die each year as a result of this evolution of bacteria against the current families of antibiotics. Caulerpa racemosa is a species of edible green alga, a seaweed in the family Caulerpaceae. There were 39 such mass spawnings during a period of 125 days and the days on which they took place showed no relation to the tidal or lunar cycles. An attempt was made to utilize the health benefits of sea grapes in human diet via biscuit as carrying medium. cylindracea is a marine Chlorophyta introduced into the Mediterranean Sea from south-western Australia. cylindracea has proved even more aggressive. Native to Australia, the Caulerpa racemosa is a green marine alga with 30 cm fronds and characteristic cluster swellings © Giuseppe Mazza. It is consumed widely in salads in Japan, Fiji, the Philippines, and Thailand. Seaweed Mariculture by Natalie Prins from the World of Algae page on the the University of the Western Cape, South Africa website: includes the culture and uses of Caulerpa racemosa . If in laboratory the alga is turned upside down, in short time gets out a stolon under and the growth resumes. Described for the first time in Australia, the Caulerpa racemosa (Forsskål) J.Agardh, 1873 is a green marine alga ( Chlorophyta) belonging to the family of the Caulerpaceae, like the well known Caulerpa prolifera of the Mediterranean or the infamous Caulerpa … In shallow water, the uprights grow much taller, more closely resembling Caulerpa Racemosa. Caulerpa racemosa (and all varieties of C. racemosa), Caulerpa cupressoides, Caulerpa verticillata, and Caulerpa floridana (California Fish and Game Code 2300). Other herbivores also grazed occasionally, but the total amount consumed was compensated for by the rapid growth of the plant and it was considered that these organisms were not likely to play a valuable role in bio-control of the plant. [6], C. racemosa reproduces vegetatively by fragmentation. These settle and after five weeks produce germ tubes which elongate and branch to develop into new plants. Piazzi., 2001. [11], Caulerpa species contain secondary metabolites that are cytotoxic, of which caulerpenyne is the most abundant. C. sertularioides is more delicate and the branchlets are rounded, compared to the flattened branchlets of C. taxifolia. On the other hand, being rich in fibres, calcium, magnesium, proteins vitamins C, A, B1 and B9, the Caulerpa racemosa is often consumed in salad by the populations of South-East Asia and even cultivated for the Japanese market. Seasonality of C. racemosa was correlated with the number of midday minus tides. One features smooth round caps, while the other has a more concave shape with thin edges. C. racemosa var. Small pieces of tissue only a few millimetres across are capable of doing this. Other American states the ban the sale of Caulerpa include Alabama, Massachusetts, … Characteristics of other varieties developed on specimens collected in the field after they were placed under altered laboratory light intensities. This is the most diverse group of algae, with over 7,000 species. There are a number of different forms and varieties, and one that appeared in the Mediterranean Sea in 1990, which is giving cause for concern as an invasive species. Caulerpa racemosa, C. laetevirens and C. peltata form a species complex. [13], Like the closely related Caulerpa lentillifera, C. racemosa is edible. IDENTIFICATION: Caulerpa racemosa is a highly variable species. Caulerpa Lentillifera is a sea weed. [9] The gametes remain motile for about 60 minutes. They are unusual because they consist of only one cell with many nuclei, making them among the biggest single cells in the world. But if the Caulerpa taxifolia sold for the aquaria has accidentally infested the prairies of Posidonia along the Mediterranean coasts, the Caulerpa racemosa with the variety Caulerpa racemosa var. Since 1990, it has been invading the Mediterranean Sea and the Canary Islands, raising ecological problems. Native to Australia, the Caulerpa racemosa is a green marine alga with 30 cm fronds and characteristic cluster swellings © Giuseppe Mazza. Somewhat different growth patterns of this species are sometimes considered to be separate species. It is also eaten by local fishermen in Malaysia and Indonesia. A number of forms and varieties for C. racemosa are listed but further study is needed to clarify their exact phylogenetic relationships. It is a giant unicellular organism with a huge number of nuclei and the chloroplasts, that serve for the chlorophyll photosynthesis, are free to move inside it for receiving better the sun rays. City of San Diego law: It is illegal to possess, sell, and transport any Caulerpa species within city limits. Caulerpa racemosa var. They grow ramifying on a creeping stolon that produces new fronds, one close to the other with the characteristic cluster swellings.When they break, due to the waves of the fishes, few millimetres fragments are sufficient to regenerate the plant. Caulerpa sp extract has potential antioxidant compounds that capable to scavenging free radicals 1,1-diphenyl-2-pycryl hydrazil picrilhidrazine [4]. The typical racemosa, upper right, has short erect branches bearing crowded ramuli with short stalks and oval or spherical tips. Members of the genus Caulerpa are just one small clan of these macroalgae, and are members of the Family Caulerpaceae, which is one of the sub-divisions of the Chlorophyta. This species resembles another Hawaiian Caulerpa species, C. sertularioides. C. racemosa was not frequent. This means that all the organism's cytoplasm is used up in the creation of the gametes and only a husk remains at the site of the original plant. Photosynthetic assimilators (branches) assume many different forms, often with rows or whorls of leaf-like pinnules. However, on the sandy bottom surrounded by P. oceanica meadow, C. racemosa has developed a dense patchy colony and completely covered the seagrass rhizomes at the centre of the colony. [2][1], A plant of C. racemosa consists of a number of branches linked to stolons which are anchored to the sandy substrate by rhizoids. Moreover, a multitude of potential treatments for various pathologies have been identified, particularly for diabetes [4] and anti-herpetic [5]. It is consumed widely in salads in Japan, Fiji, the Philippines, and Thailand. The rising branches are also more rounded toward apices, compared to the more angular, squared-off branches of … [7], C. racemosa can also reproduce sexually and in so doing exhibits holocarpy. Like many other species of this genus, Caulerpa taxifolia has some unique growth characteristics, besides being siphonous, that promote its invasiveness in habitats where it is not native: It can "heal" wounds almost immediately after being damaged by producing a … The genus Caulerpa comes from the Greek (καυλόϛ) “caulós” = stalk, stem and from (ἕρπω) “herpo” = to creep, whilst the name of the species racemosa comes from the Latin “racemósus, a, um” = in clusters, due to the curious look of the laminae as is highlighted by the English name of “Sea Grapes” or the French one of “Caulerpe raisin”. Synonyms : Caulerpa clavifera (Turner) C.Agardh, 1817; Caulerpa clavifera var. [4], C. racemosa is widely distributed in shallow temperate and tropical seas. The properties are believed to come from a strain of rare endophytic actinomycetes that lives in symbiosis with C. racemosa and more particularly of the secondary metabolites produced (flavonoids and alkaloids [2] ). Normally, "Grape Caulerpa" is Caulerpa racemosa, or one of the variations of C. racemosa. uvifera (C.Agardh) J.Agardh, 1873; Caulerpa uvifera C.Agardh, 1817; Chauvinia clavifera (Turner) Bory de Saint-Vincent, 1829; Chauvinia clavifera var. They are the sister group to Microthmaniales. Sea grapes (Caulerpa racemosa), a common tropical green seaweed, has immense nutritional potential. There are nine banned species of Caulerpa in the State of California, including Caulerpa racemosa and Caulerpa mexicana, two ornamental species described elsewhere in this article. uvifera (C.Agardh) C.Agardh, 1823; Caulerpa feldmannii Rayss & Edelstein, 1960; Caulerpa obtusa J.V.Lamouroux, 1809; Caulerpa racemosa var. Nothing surprising, therefore, that this is considered as an invasive species.
