Tiger Tail Sea Cucumber Scuba Diving in Cozumel Mexico [Underwater Video]

Tiger Tail Sea Cucumber (Holothuria thomasi) While Scuba Diving in Cozumel

Have you seen this strange creature underwater? It’s called the Tiger’s Tail or Tiger Tail Sea Cucumber (Holothuria thomasi) and, as an echinoderm, it is related to other sea creatures like starfish and sea urchins!

It’s the largest of all sea cucumbers and can stretch to about 6 feet long while feeding on detritus in the sand.  This sea cucumber stretches out from it’s home gradually, sweeping back and forth in a large arc, using it’s mouth to suck in sand and feed on small particles like fish waste, very small marine creatures and algae.

We see them pretty often while scuba diving here in Cozumel but what’s unique about this specific example is that this Tiger Tail’s other end is in a hole in the sand rather than secured to a crack in the reef. That was pretty noteworthy!

    Yes I have some photos of one from a Cozumel night dive, coming out from under a reef overhang. I estimated it was 8 feet long but I could not even see the far end of it. Crazy!
