Thelenota is a genus of sea cucumber in the family Stichopodidae. [1] [2]
They are massive sea cucumbers, more or less rectangular in cross-section. The oral face (called trivium) is flat, and covered with numerous aligned podia. The tegument is thick, and covered with thick papillae and other tubercles. The oral tentacles are peltate, helping to collect the sediment to ingest.
An echinoderm is any member of the phylum Echinodermata of marine animals. The adults are recognizable by their radial symmetry, and include starfish, sea urchins, sand dollars, and sea cucumbers, as well as the sea lilies or "stone lilies". Adult echinoderms are found on the sea bed at every ocean depth, from the intertidal zone to the abyssal zone. The phylum contains about 7000 living species, making it the second-largest grouping of deuterostomes, after the chordates. Echinoderms are the largest phylum that has no freshwater or terrestrial members.
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. Sea cucumbers are found on the sea floor worldwide. The number of holothurian species worldwide is about 1,717 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 degradation process.

Sandfish may refer to:
Tube feet are small active tubular projections on the oral face of an echinoderm, whether the arms of a starfish, or the undersides of sea urchins, sand dollars and sea cucumbers; they are more discreet though present on brittlestars, and have only a feeding function in feather stars. They are part of the water vascular system.
The Stichopodidae are a family of sea cucumbers, part of the order Synallactida.
Sea cucumbers are marine animals of the class Holothuroidea. They are used as food, in fresh or dried form, in various cuisines. In some cultural contexts the sea cucumber is thought to have medicinal value.
The orange-footed sea cucumber is the largest sea cucumber in New England, United States. It is one of the most abundant and widespread species of holothurians within the North Atlantic Ocean and the Barents Sea (Russia), being most abundant along the eastern coast of North America.
Thelenota ananas, also known as pineapple sea cucumber, oloturia ananas, tripang, prickly skin cucumber, pointed teat sea cucumber, armoured sea cucumber, giant sea cucumber, sand fish or prickly redfish, is a species of sea cucumber found in tropical Indo-Pacific waters from the Red Sea and East Africa to Hawaii and Polynesia.
Holothuriidae is a family of sea cucumbers, a type of echinoderm.
The worm pearlfish is an eel-like fish in the family Carapidae.
Sea cucumber stocks have been overexploited in the wild, resulting in incentives to grow them by aquaculture. Aquaculture means the sea cucumbers are farmed in contained areas where they can be cultured in a controlled manner. In China, sea cucumbers are cultured, along with prawns and some fish species, in integrated multi-trophic systems. In these systems, the sea cucumbers feed on the waste and feces from the other species. In this manner, what would otherwise be polluting byproducts from the culture of the other species become a valuable resource that is turned into a marketable product.
The pinhead pearlfish, Encheliophis boraborensis, is a species of slender, ray-finned fish in the family Carapidae found in the tropical Indo-Pacific Ocean; it normally lives inside the body cavity of a sea cucumber such as the pineapple sea cucumber or the leopard sea cucumber.
The silver pearlfish, Encheliophis homei, is a species of eel-like fish in the family Carapidae. This pearlfish lives inside the coelom of sea cucumbers such as Bohadschia argus, Thelenota ananas , and Stichopus chloronotus. It is native to tropical and subtropical parts of the Indo-Pacific Ocean.
Elpidiidae is a family of deep-sea sea cucumbers.
Synallactida is a rankless clade of sea cucumbers, but is referred to as an order. Taxa within Synallactida were previously classified in an order called Aspidochirotida, which was determined to be polyphyletic in 2017.
Thelenota rubralineata is a species of sea cucumber in the family Stichopodidae, in the phylum Echinodermata, mainly located in the central Indo-Pacific region. It has a distinctive coloring pattern, and can be found on the seabed near coral. T. rubralineata is part of the Thelenota genus, characterized by their large size and the presence of a calcareous ring.
Thelenota anax is a species of sea cucumber mostly found in the tropical, South Pacific Ocean. It is also commonly known as the amber fish. Some other names for T. anax are black teatfish, blackfish, brownfish, chief sea cucumber, curryfish, elephant trunk cucumber, lollyfish, tripang, and white-teat sea cucumber. T. anax is found on sandy ocean bottoms and often have ectocommensal relationships. They are commonly fished commercially and exported because of their medicinal properties and large size.
Thyone roscovita is a species of sea cucumber in the family Phyllophoridae. It is found on gravel, sand and mud substrates in the northeastern Atlantic Ocean and the Mediterranean Sea at depths down to about 40 m (130 ft). It is a suspension feeder and catches food particles floating past with its branched feeding tentacles.
