Tag: Black-Fringed Sea Cucumber (Holothuria Leucospilota)

The Black-Fringed Sea Cucumber (Holothuria Leucospilota) is one of the most common species of Sea Cucumber in local waters.

Although at first glance it appears similar to the closely related Black Sea Cucumber (Holothuria Atra), the most noticeable differences between the two species are the prominent "papullae" on the skin of H. Leucospilota, as opposed to the smooth skin of H. Atra.

The second obvious difference between these two species is that whilst H. Atra appears rather short and squat, H. Leucospilota is noticeably longer and thinner.

Both of these species are found in similar habitats, however the Black-Fringed Sea Cucumber is often found with most of its body concealed beneath an overhanging rock or coral, with only the fore end protruding.

As with many of its relatives, the Black-Fringed Sea Cucumber's primary defense against attack is to eject parts of its intestines or respiratory system in the form of sticky white threads (cuvierian tubules).
