Scotoplanes live on deep ocean bottoms, specifically on the abyssal plain in the Atlantic, Pacific and Indian Oceans, typically at depths of over 1,200 to 5,000 meters (3,900 to 16,400 feet) [5][6] Some related species can be found in the Antarctic. Scotoplanes (and all deep-sea holothurians) are deposit feeders and obtain food by extracting ...
Bohadschia argus has the same roughly cylindrical body plan shared by most sea cucumbers. On average, it measures approximately 36 cm (14 in) in length and 1.8 to 2.2 kg (4.0 to 4.9 lb) in weight, with a maximum recorded length of 60 cm (24 in). Its tough outer body wall, around 10 mm (0.39 in) in thickness, is firm and leathery to the touch.
Genera. see Taxonomy. Chiridotidae is a family of sea cucumbers found in the order Apodida. Within the family, there are 16 recognized genera all with different ranges of body types and functions. [1] Sea cucumbers play a fundamental role in many marine ecosystems.
Aquatic respiration. Sea slugs respire through a gill (or ctenidium) Aquatic respiration is the process whereby an aquatic organism exchanges respiratory gases with water, obtaining oxygen from oxygen dissolved in water and excreting carbon dioxide and some other metabolic waste products into the water.
Sea cucumbers are marine invertebrates and are closely related to sea urchins and starfish. All these groups tend to have radial symmetry and have a water vascular system that operates by hydrostatic pressure, enabling them to move around by use of many suckers known as tube feet. Sea cucumbers are usually leathery, gherkin-shaped animals with ...
A fisher will take the cucumber from the water and place it in a bucket for a few hours to let it pass any sand from its gut. The fisher will then cut out its intestine and sometimes its respiratory system and gonads, as well, and release the still-living animal. The viscera are eaten raw and fresh, or bottled and sold in the community.
