Sea Cucumbers

The image shown is a representative illustration and does not depict every individual animal in this category.

Total number of species approx.: 1700

Sea cucumbers are soft-bodied marine animals found on ocean floors worldwide, from shallow coastal areas to the deep sea. They are part of the echinoderm group, related to starfish and sea urchins, but have elongated, flexible bodies. They move slowly across the seabed, using tube feet and muscular contractions, feeding on organic matter mixed with sand. This feeding behavior helps clean and recycle nutrients within marine ecosystems.

Sea cucumbers play an important role as natural recyclers, breaking down organic decomposition products (detritus) and improving sediment quality. Some species have unique defense mechanisms, such as expelling sticky threads or even internal organs to deter predators. Despite their importance, sea cucumbers are vulnerable to overfishing and environmental changes. Protecting them is essential for maintaining healthy ocean ecosystems and balanced seafloor habitats.
