About Sea Cucumber: 

  • These are part of a larger animal group called echinoderms and are invertebrates that live on the seafloor.
  • Their body shape is similar to a cucumber, but they have small tentacle-like tube feet that are used for locomotion and feeding.
  • There are about 1,250 species of sea cucumber, all of which belong to the taxonomic class Holothuroidea.
  • They are found in all marine environments throughout the world, from shallow to deep-sea environments. Sea cucumbers are benthic, meaning they live on the ocean floor.
  • They excrete inorganic nitrogen and phosphorus, enhancing the productivity of benthic biota.
  • Reproduction:
    • Sea cucumbers exhibit sexual and asexual reproduction.
    • Unlike most terrestrial animals, sea cucumber eggs undergo external fertilization—females release eggs into the water that are fertilized when they come into contact with sperm that males have released.
  • Conservation status
    • Wildlife Protection Act of 1972: Schedule I
    • CITES: Appendix II
