Tag: Chalky Sea Cucumber (Bohadschia Marmorata)

Growing to a maximum length of approximately 30cm, the Chalky Sea Cucumber (Bohadschia Marmorata) is another species that, although reasonably common in local waters, is not found in great numbers.

This species is most commonly found on shallow sandy/rubble reef flats where it can sometimes be found partially buried in the substrate.

The main identifying features of the Chalky Sea Cucumber are its overall pale yellow-ish colouration, (with or without mottled brown patches) and covering of numerous small brown spots.

As with many species of Sea Cucumber, the primary defense of this species is the ability to expel the respiratory organs or intestines (which are subsequently regenerated)in the form of sticky white threads known as cuvierian tubules.

It is NOT considered appropriate behaviour to harass the animal in order to witness this is a defensive mechanism.
