Actinopyga agassizii, commonly known as the five-toothed sea cucumber or West Indian sea cucumber, [1] is a species of sea cucumber in the family Holothuriidae. It was first described by German zoologist Emil Selenka in 1867. It is native to the Western Atlantic region, including the Gulf of Mexico and the Caribbean Sea, and is harvested for food.
Actinopyga agassizii grows to a maximum length of approximately 35 cm (14 in). It has a white ground color with scattered yellow-brown spots. Its skin is thick and leathery, and its upper side is lined with papillae (conical fleshy protuberances) while rows of tube feet are found on its bottom side. It has five calcareous teeth surrounding its anus, a characteristic from which one of its common names is derived. [6] [7] [8]
Actinopyga agassizii is found in the tropical Western Atlantic region, its range extending from the Gulf of Mexico to the Caribbean Sea. It is also found off the coasts of Bermuda. It is nocturnal and inhabits rocky areas, coral reefs, and sea grass beds at depths between 0 and 54 m (177 ft). [1] [6]
Actinopyga agassizii feeds on detritus on algal turfs and sea grass beds and in sandy or rocky areas. An individual possesses only one of the two sexes and has a single gonad. It spawns and fertilizes both externally and may show signs of brooding. Its life cycle consists of the embryo growing into a free-swimming larva before developing a barrel-shaped body and later undergoing metamorphosis to turn into a juvenile sea cucumber. As a mode of self-defence, it can expel clusters of sticky threads called Cuvierian tubules which contain a toxic saponin named holothurin that can paralyze other animals. [6] [8] [9]
Actinopyga agassizii is caught for food in small-scale artisanal fisheries. However, the quantities and the locations in which it is fished are currently unknown. It is less popular among fisheries compared with other sea cucumber species, although its popularity may rise when other species with higher demands are exhausted in numbers. As of its last assessment in 2010, the IUCN Red List considers Actinopyga agassizii to be a least-concern species. [1]
Sea cucumbers are echinoderms from the class Holothuroidea. They are marine animals with a leathery skin and an elongated body containing a single, branched gonad. They are found on the sea floor worldwide. The number of known holothurian species worldwide is about 1,786, with the greatest number being in the Asia-Pacific region. Many of these are gathered for human consumption and some species are cultivated in aquaculture systems. The harvested product is variously referred to as trepang, namako, bêche-de-mer, or balate. Sea cucumbers serve a useful role in the marine ecosystem as they help recycle nutrients, breaking down detritus and other organic matter, after which bacteria can continue the decomposition process.
The green sea turtle, 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, due to its diet strictly being seagrass, not to the color of its carapace, which is olive to black.
The gag grouper, also known as velvet rockfish, the gag, or charcoal belly, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It comes from warmer parts of the West Atlantic, including the Caribbean and Gulf of Mexico. It is a drab, mottled-gray fish lacking the distinguishing features of most other groupers. Its pattern of markings resemble the box-shaped spots of the black grouper. It lacks the streamer-points on the tail fin that scamp and yellowmouth grouper have and lacks yellow coloration around the mouth.
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. This common species is found in warm parts of the Atlantic Ocean.
The night shark is a species of requiem shark, in the family Carcharhinidae, found in the temperate and tropical waters of the Atlantic Ocean. An inhabitant of the outer continental shelf and upper continental slope, this shark most commonly occurs at depths of 50–600 m (160–1,970 ft) and conducts a diel vertical migration, spending the day in deeper water and moving into shallower waters at night. Off northeastern Brazil, large numbers congregate around seamounts of varying depths. A slender, streamlined species, the night shark typically reaches a length of 2 m (6.6 ft). It can be identified by its long, pointed snout and large, green eyes, and is dark grayish blue or brown above and white below.
Sea cucumbers are marine animals of the class Holothuroidea. They can be used as food, in fresh or dried form, in various cuisines. In some cultural contexts the sea cucumber is thought to have medicinal value.

Apostichopus japonicus is a species of sea cucumber in the family Stichopodidae. It is found in shallow temperate waters along the coasts of south east Asia and is commonly known as the Japanese spiky sea cucumber or the Japanese sea cucumber.
Holothuria parvula, the golden sea cucumber, is a species of echinoderm in the class Holothuroidea. It was first described by Emil Selenka in 1867 and has since been placed in the subgenus Platyperona, making its full scientific name Holothuria (Platyperona) parvula. It is found in shallow areas of the Caribbean Sea and Gulf of Mexico and is unusual among sea cucumbers in that it can reproduce by breaking in half.
