  2. 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 (/ ˌ h ɒ l ə ˈ θj ʊər i ə n, ˌ h oʊ-/) species worldwide is about 1,717 with the greatest number being in the Asia Pacific region
  3. Class Holothuroidea is a sister clade to class Echinoidea, which together make up the clade Echinozoa. Highly simplified overview of Echinodermata phylogeny based in part on the hypothesis of relationships presented by Reich et al. (2015)
  4. The Holothuroidea, or sea cucumbers, are an abundant and diverse group of worm-like and usually soft-bodied echinoderms. They are found in nearly every marine environment, but are most diverse on tropical shallow-water coral reefs. They range from the intertidal, where they may be exposed briefly at low tide, to the floor of the deepest oceanic.
  5. Subclass Holothuroidea incertae sedis (temporary name) Subclass Actinota accepted as Actinopoda. Subclass Dendrochirotacea accepted as Actinopoda (All recent evidence indicates this is not a subclass) Subclass Elpidiacea accepted as Actinopoda. Subclass Holothuriacea accepted as Actinopoda.

Holothuroidea are commonly known as Sea Cucumbers, or Sea Slugs, with approximately 1,400 species found globally. They are found in all oceans worldwide and at all depths, although they are most common and show increased diversity around tropical shallow-water reefs. The vast majority are benthic, bottom feeders, with a few.
