Cucumaria okhotensis is a species of sea cucumber belonging to the family Cucumariidae. This species is commonly found in various marine environments, contributing to the biodiversity of these ecosystems.
Description & Characteristics
Cucumaria okhotensis exhibits the typical sea cucumber body shape: elongated and cylindrical, with a soft, leathery skin. It is often found in a variety of colors, including brown, gray, and green. The size of Cucumaria okhotensis varies, but it can reach a maximum length of approximately 15 centimeters.
Habitat and Occurrence
Cucumaria okhotensis is a common inhabitant of the subtidal zone, particularly in rocky and sandy substrates. Its distribution extends across a range of marine zones, including the neritic zone, which encompasses the coastal waters above the continental shelf. This species can be found at depths ranging from the intertidal zone to approximately 100 meters.
Taxonomy
Cucumaria okhotensis is classified within the phylum Echinodermata, which encompasses a diverse group of marine invertebrates. Within this phylum, it belongs to the Class Holothuroidea, which includes all sea cucumbers. The Order Dendrochirotida further categorizes it, encompassing sea cucumbers with branched tentacles. Cucumaria okhotensis is finally classified within the Family Cucumariidae, a group of sea cucumbers distinguished by their smooth bodies and lack of cuvierian tubules.
Feeding
Cucumaria okhotensis is a deposit feeder, meaning it primarily consumes organic matter and sediment from the seabed. Its branched tentacles are crucial for this process, as they are used to gather food particles from the surrounding environment.
