Submarine donkey dung

This post is also available in: Dutch.

This video shows one of the weirder animals in our waters. Its appearance has led to its common name ‘donkey dung sea cucumber’, and scientists refer to it as Holothuria mexicana. On Curacao it is known as the Lol’i awa, which translates into something that is not printable! These slow moving animals are an important link in the food chains of inner bays. They slowly but surely filter the sandy bottom, extracting organic particles from the sand as they go (basically waste products raining down from the water column, such as fish fecal matter), and discharge worm-like piles of cleaned sand. For these creatures dirt is a delicacy. They are real specialists in marine waste treatment!
