The Dragonfish, Peanutfish, Selenka’s Sea Cucumber, Warty Sea Cucumber, scientifically known as Stichopus horrens, is a fascinating creature of the deep sea. This echinoderm, with its distinctive warty appearance, plays a crucial role in the marine ecosystem.
Description & Characteristics
Stichopus horrens can grow to a considerable size, reaching a maximum length of about 20-30 centimeters. Its body is elongated and cylindrical, covered in numerous prominent warts or papillae, giving it a rough and warty texture. The color of this sea cucumber can vary, ranging from reddish-brown to grayish-green, depending on its habitat and diet.
Habitat and Occurrence
Stichopus horrens is a common inhabitant of the subtidal, sublittoral, and infralittoral zones of the oceans. It is particularly prevalent in the deep zone, ranging from the lower limit of the intertidal zone to the shelf edge at approximately 200 meters depth. This species is often found in neritic environments, where it plays a crucial role in nutrient cycling.
Taxonomy
Stichopus horrens belongs to the Class: Holothuroidea, Order: Synallactida, and Family: Stichopodidae. This classification highlights its close relation to other sea cucumbers and underscores its importance within the broader echinoderm lineage.
Feeding
Stichopus horrens is a detritivore, feeding primarily on organic debris, plankton, and sediment. It plays a vital role in the marine ecosystem by breaking down and recycling organic matter, contributing to the overall health of the ocean floor.
