Black Sea Cucumber

(Holothuria atra)

Holothuria Sea Cucumbers are generally found in oceans worldwide, from shallow coastal areas to deep-sea habitats. Holothuria Sea Cucumbers are detritivores and scavengers, feeding on decaying organic matter, detritus, plankton, and small particles from the substrate. Sea Cucumbers play an important role in marine ecosystems by recycling nutrients and contributing to the breakdown of organic matter. They inhabit various substrates, including sandy or muddy bottoms, rocky reefs, and seagrass beds. Some sea cucumber species have defensive mechanisms, such as expelling their internal organs or releasing toxic substances, as a defense against predators. This can be harmful to the animal and should be avoided in an aquarium environment. Invertebrates do not tolerate copper medications and are sensitive to salinity changes.

Holothuria atra are also sometimes known as Black Sea Cucumbers or Lollyfish. They are generally not seen in the aquarium trade. The Black Sea Cucumbers is generally black or dark gray in color. They can grow up to 24".
