Favorite Images of Sea Cucumbers

Animals list created by kathy Avatar


A list of my favorite images of sea cucumbers.

en.wikipedia.org/wiki/Sea_cucumber

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 1,716 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, 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.

Like all echinoderms, sea cucumbers have an endoskeleton just below the skin, calcified structures that are usually reduced to isolated microscopic ossicles (or sclerietes) joined by connective tissue. In some species these can sometimes be enlarged to flattened plates, forming an armour. In pelagic species such as the Sea Cucumber (Order Elasipodida, family Pelagothuriidae), the skeleton and a calcareous ring are absent.

The sea cucumbers are named for their resemblance to the vegetable cucumber.
