Ocnus lacteus is a species of sea cucumber belonging to the family Cucumariidae. This species is commonly found in various marine habitats, highlighting its adaptability and prevalence in the wider ocean ecosystem.
Description & Characteristics
Ocnus lacteus, like other sea cucumbers, possesses a cylindrical body shape. It is typically characterized by its smooth, milky-white skin, which gives rise to its common name “Milky Sea Cucumber.” This species is a relatively small sea cucumber, reaching a maximum size of approximately 5 centimeters in length. Its body is covered in numerous small, fleshy papillae, which are particularly noticeable around the mouth region. These papillae play a vital role in feeding, facilitating the capture and ingestion of food particles.
Habitat and Occurrence
Ocnus lacteus exhibits a preference for shallow, coastal environments. It is commonly found in rocky intertidal zones, tide pools, and seagrass meadows, often residing in close proximity to the shoreline. This species is a prevalent presence in these aquatic ecosystems. These habitats provide the necessary food sources and shelter for Ocnus lacteus to thrive.
Taxonomy
Ocnus lacteus belongs to the Class: Holothuroidea, Order: Dendrochirotida, and Family: Cucumariidae. This classification highlights its evolutionary lineage within the echinoderm phylum, a group of marine invertebrates characterized by a spiny skin.
Feeding
Ocnus lacteus is a deposit feeder, primarily consuming organic debris and sediments found in its habitat. It uses its tentacles, covered in sticky mucus, to capture and transport food particles into its mouth. This feeding strategy contributes to the maintenance of a healthy marine environment by removing organic waste and recycling nutrients within the ecosystem.
