Cucumariidae
Cucumariidae is a family of sea cucumbers within the order Dendrochirotida, commonly known as sea cucumbers. They are found in all oceans worldwide, particularly in shallow and intertidal zones. These echinoderms are characterized by their elongated, cylindrical bodies, often with a distinct oral and anal opening. They are known for their ability to regenerate lost body parts, making them a resilient species in the face of predation.
Common Names
Cucumariidae are commonly known as sea cucumbers, a name shared with other families within the Holothuroidea class. However, within the family, specific species may have other common names depending on their unique characteristics or locations.

- Elongated, Cylindrical Body: They are typically elongated and cylindrical, with a distinct oral and anal opening.
- Five Rows of Tube Feet: Like all sea cucumbers, they have five rows of tube feet, which are used for locomotion and feeding.
- Branching Tentacles: Their oral tentacles are branched, hence their classification within the Dendrochirotida order.
- Regeneration: They have remarkable regenerative abilities, capable of regrowing lost body parts.
- Diverse Colors: Cucumariidae can be found in a wide range of colors, from shades of brown and gray to bright reds and yellows.
Environments
Cucumariidae sea cucumbers are widespread throughout the world's oceans, with a preference for shallow and intertidal zones. They can be found in various environments, including:
- Rocky Shores: Often found clinging to rocks or in crevices.
- Sandy Bottoms: Can be found burrowing in the sand or sediment.
- Coral Reefs: They are common inhabitants of coral reefs, where they contribute to nutrient cycling.
- Seagrass Beds: They may be found in seagrass beds, often feeding on detritus and algae.
