Marinha Do Arvoredo Biological Reserve
Arvoredo Marine Biological Reserve ( pt, Reserva Biológica Marinha do Arvoredo) is a Biological reserve off the coast of the Santa Catarina state, Brazil. Location The Biological Reserve, which covers , was established on 12 March 1990. It lies in the municipalities of Bombinhas, Florianópolis and Governador Celso Ramos of the state of Santa Catarina. The reserve is a transition region for seaweed flora, including organisms typical of both temperate and tropical regions. The reserve is close to the Subtropical Convergence where the Brazil Current from the north converges with the Falkland Current from the south. The surface waters are dominated by the Tropical Shelf Water while below in depth the water is from the South Atlantic Central Water. The Arvoredo archipelago (27°17' S; 48°28' W) is formed by three islands (Arvoredo, Galés and Deserta) and a rocky outcrop (São Pedro). The archipelago lies over the continental platform and is characterized by the presence of Preca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Green Sea Turtle
The green sea turtle (''Chelonia mydas''), also known as the green turtle, black (sea) turtle or Pacific green turtle, is a species of large sea turtle of the family Cheloniidae. It is the only species in the genus ''Chelonia''. Its range extends throughout tropical and subtropical seas around the world, with two distinct populations in the Atlantic and Pacific Oceans, but it is also found in the Indian Ocean. The common name refers to the usually green fat found beneath its carapace, not to the color of its carapace, which is olive to black. The dorsoventrally flattened body of ''C. mydas'' is covered by a large, teardrop-shaped carapace; it has a pair of large, paddle-like flippers. It is usually lightly colored, although in the eastern Pacific populations, parts of the carapace can be almost black. Unlike other members of its family, such as the hawksbill sea turtle, ''C. mydas'' is mostly herbivorous. The adults usually inhabit shallow lagoons, feeding mostly on various ...

Atlantic Yellow-nosed Albatross
The Atlantic yellow-nosed albatross (''Thalassarche chlororhynchos'') is a large seabird in the albatross family Diomedeidae. This small mollymawk was once considered conspecific with the Indian yellow-nosed albatross and known as the yellow-nosed albatross. Some authorities still consider these taxa to be conspecific, such as the Clements checklist and the SACC, which recognizes that a proposal is needed. Taxonomy The Atlantic yellow-nosed albatross was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the albatrosses in the genus '' Diomedea'' and coined the binomial name ''Diomedea chlororhynchos''. Gmelin based his description on the "yellow-nosed albatross" that had been described and illustrated in 1785 by the English ornithologist John Latham from a specimen that had been collected off the coast of the Cape of Good Hope. The Atlantic yellow-nosed alba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White-chinned Petrel
The white-chinned petrel (''Procellaria aequinoctialis'') also known as the Cape hen and shoemaker, is a large shearwater in the family Procellariidae. It ranges around the Southern Ocean as far north as southern Australia, Peru and Namibia, and breeds colonially on scattered islands. The white-chinned petrel was formerly considered to be conspecific with the spectacled petrel (''Procellaria conspicillata''). Taxonomy In 1747 the English naturalist George Edwards included an illustration and a description of the white-chinned petrel in the second volume of his ''A Natural History of Uncommon Birds''. He used the English name "The great Black Peteril" and based his hand-coloured etching on a preserved specimen that had been brought to London. He believed that it had been collected near the Cape of Good Hope. When in 1758 the Swedish naturalist Carl Linnaeus updated his '' Systema Naturae'' for the tenth edition, he placed the white-chinned petrel with the other petrels in th ...

Sea Urchin
Sea urchins () are spiny, globular echinoderms in the class Echinoidea. About 950 species of sea urchin live on the seabed of every ocean and inhabit every depth zone from the intertidal seashore down to . The spherical, hard shells (tests) of sea urchins are round and spiny, ranging in diameter from . Sea urchins move slowly, crawling with tube feet, and also propel themselves with their spines. Although algae are the primary diet, sea urchins also eat slow-moving (sessile) animals. Predators that eat sea urchins include a wide variety of fish, starfish, crabs, marine mammals. Sea urchins are also used as food especially in Japan. Adult sea urchins have fivefold symmetry, but their pluteus larvae feature bilateral (mirror) symmetry, indicating that the sea urchin belongs to the Bilateria group of animal phyla, which also comprises the chordates and the arthropods, the annelids and the molluscs, and are found in every ocean and in every climate, from the tropics to the pol ...

Decapoda
The Decapoda or decapods (literally "ten-footed") are an order of crustaceans within the class Malacostraca, including many familiar groups, such as crabs, lobsters, crayfish, shrimp and prawns. Most decapods are scavengers. The order is estimated to contain nearly 15,000 species in around 2,700 genera, with around 3,300 fossil species. Nearly half of these species are crabs, with the shrimp (about 3,000 species) and Anomura including hermit crabs, porcelain crabs, squat lobsters (about 2500 species) making up the bulk of the remainder. The earliest fossil decapod is the Devonian ''Palaeopalaemon''. Anatomy Decapods can have as many as 38 appendages, arranged in one pair per body segment. As the name Decapoda (from the Greek , ', "ten", and , '' -pod'', "foot") implies, ten of these appendages are considered legs. They are the pereiopods, found on the last five thoracic segments. In many decapods, one pair of these "legs" has enlarged pincers, called chelae, with the legs be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isostichopus Badionotus
''Isostichopus badionotus'', also known as the chocolate chip cucumber or the cookie dough sea cucumber, is a species of sea cucumber in the family Stichopodidae.

Eucidaris Tribuloides
''Eucidaris tribuloides'', the slate pencil urchin, is a species of cidaroid sea urchins that inhabits littoral regions of the Atlantic Ocean. As a member of the basal clade, basal echinoid order Cidaroida, its morphological, developmental and molecular genetic characteristics make it a phylogenetically interesting species. Taxonomy ''Eucidaris tribuloides'' was first described and classified by Jean Baptiste Lamarck in 1816 as ''Cidarites tribuloides''. The modern classification stems from the echinoid treatises by Pomel in 1883 and by Döderlein in 1887. Distribution and habitat The slate pencil urchin can be found on both sides of the Atlantic, and throughout the Caribbean. On the western side of the Atlantic, the slate pencil urchin has been found as far north as Cape Hatteras, North Carolina, and as far south as Rio de Janeiro. In the Gulf of Mexico, populations have been reported at Scorpion Reef, Alacran Reef, Campeche Bank. On the eastern side of the Atlantic, a ...

Goby
Goby is a common name for many species of small to medium sized ray-finned fish, normally with large heads and tapered bodies, which are found in marine, brackish and freshwater environments. Traditionally most of the species called gobies have been classified in the order Perciformes as the suborder Gobioidei but in the 5th Edition of ''Fishes of the World'' this suborder is elevated to an order Gobiiformes within the clade Percomorpha. Not all the species in the Gobiiformes are referred to as gobies and the "true gobies" are placed in the family Gobiidae, while other species referred to as gobies have been placed in the Oxudercidae. Goby is also used to describe some species which are not classified within the order Gobiiformes, such as the engineer goby or convict blenny ''Pholidichthys leucotaenia''. The word goby derives from the Latin ''gobius'' meaning "gudgeon", and some species of goby, especially the sleeper gobies in the family Eleotridae and some of the dartfishes are ...

Tube-dwelling Anemone
Tube-dwelling anemones or ceriantharians look very similar to sea anemones but belong to an entirely different class of anthozoans. They are solitary, living buried in soft sediments. Tube anemones live inside and can withdraw into tubes, which are composed of a fibrous material made from secreted mucus and threads of nematocyst-like organelles known as ptychocysts. Within the tubes of these ceriantharians, more than one polyp is present, which is an exceptional trait because species that create tube systems usually contain only one polyp per tube. Ceriantharians were formerly classified in the taxon Ceriantipatharia along with the black corals but have since been moved to their own subclass, Ceriantharia. Ceriantharians have a crown of tentacles that are composed of two whorls of distinctly different sized tentacles. The outer whorl consists of large tentacles that extend outwards. These tentacles taper to points and are mostly used in food capture and defence. The smaller inn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Narrownose Smooth-hound
The narrownose smooth-hound (''Mustelus schmitti'') is a houndshark of the family Triakidae. It is found on the continental shelves of the subtropical southwest Atlantic, from southern Brazil to northern Argentina, between latitudes 30° S and 44° S, at depths between 60 m to 195 m. It can reach a length of 74 centimeters. Narrownose smooth-hounds feed on crabs and probably other crustacean Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapoda, decapods, ostracoda, seed shrimp, branchiopoda, branchiopods, argulidae, fish lice, krill, remipedes, isopoda, isopods, barnacles, copepods, ...s, and presumably small fishes. Narrownose smooth-hounds are also caught and utilized for human consumption. The reproduction of this houndshark is ovoviviparous, with 2 to 7 pups per litter, and a birth length of about 26 cm.

La Plata Dolphin
The La Plata dolphin, franciscana or toninha (''Pontoporia blainvillei'') is a species of dolphin found in coastal Atlantic waters of southeastern South America. It is a member of the river dolphin group and the only one that lives in the ocean and saltwater estuaries, rather than inhabiting exclusively freshwater systems. Commercialized areas that create agricultural runoffs and industrialized zones can affect the health of the La Plata dolphin, especially in regards to their contributions of waste and pollution, which can lead to habitat degradation and poisoned food among other concerns. Taxonomy The La Plata dolphin is the only species in its genus, ''Pontoporia'', and is often placed in its own family, Pontoporiidae. It was first described by Paul Gervais and Alcide d'Orbigny in 1844 (the species epithet ''blainvillei'' commemorates the French zoologist Henri Marie Ducrotay de Blainville). The La Plata dolphin is also widely known as the ''Franciscana'' - the Argentine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
