[Coral-List] Sea Cucumber

[Paul Humann]

Hi Lad, et al,

It turns out that the red "worm" is indeed a sea cucumber (I was wrong). 
It is Neothyonidium parvum (no common name), Family Phyllophoridae, a 
relatively uncommon shallow water species (except common in Brazil) 
ranging from Florida to Brazil. It may be more common that thought 
because it is a burrowing species (and consequently rarely observed) 
which is usually found buried in the sand in and around sea grass beds. 
It grows to about 3 in. in length.
