Family Holothuriidae
updated Oct 2016

Where seen? This small smooth reddish orange sea cucumber does resemble a kumquat! It is sometimes seen on our Southern shores.

Features: About 8cm long. Body oval with a smooth skin and lots of slender tube feet scattered all over it. It has an obvious flat underside which has lots more tube feet than the upper side. Feeding tentacles have flowery tips. It may be the same as the Actinopyga sp. in Lane's guide of which "just a single specimen was seen, from the reef slope of Sultan Shoal".
