Two sea cucumber species Thelenota ananas (prickly redfish) and Stichopus chloronotus (greenfish) have been found capable of asexual propagation through transverse fission, [7] the process whereby an organism is cut in half and completely regenerates the missing half. Rubber bands are placed around the middle of the sea cucumbers which induces ...
The sea cucumber will be fully regenerated within 144 hours of transection. If a transection of a sea cucumber is made posteriorly to the crossover point, then the esophagus, the stomach, and the intestine will all be represented in the final form of the sea cucumber. Similar processes as regeneration of an anterior transection will occur, and ...

It is monotypic, being represented by the single species Australostichopus mollis, [2] commonly known as the brown sea cucumber or Australasian sea cucumber. [3] This species has stimulated interest for its fishery potential in the Southern Hemisphere, [ 4 ] and for its capability to reduce waste produced by aquaculture .
The warty sea cucumber can reach a maximum length of 30–40 cm (1 ft 0 in – 1 ft 4 in). [2] It has a soft, cylindrical body, with red-brown to yellowish leathery skin. There are numerous grey spots along its body, hence the name "warty." It has an endoskeleton just below the skin. The mouth and anus are on opposite sides of the body.
Astichopus multifidus is a robust, soft-bodied species growing to a maximum length of 40 cm (16 in) and width of 10 cm (4 in). Both its dorsal and ventral surfaces are uniformly covered with hundreds of tube feet, those on the dorsal surface being extended into papillae, fleshy conical projections about 1 cm (0.4 in) long with tube feet at their tips.
Sclerodactyla briareus is an elongated oval or cigar-shaped sea cucumber and grows to about 15 centimetres (5.9 in). It often adopts a characteristic pose with both ends raised above the substrate. At the anterior end there is a mouth surrounded by a ring of ten, short, branched feeding tentacles. [2]
