Hello,
I've recently observed Eupleura sulcidentata clinging to the tips of sea
grass blades in quiet NW Florida bays.  This is interesting behavior for a
carnivore, but it may be to avoid predation from the abundant crabs in the
area.  Has anyone out there observed this behavior while snorkeling or
scuba diving?  Might there be some sort of food source (i.e. tiny
animals/worms) on these blades of grass that E. sulcidentata is seeking?
This species is very small for the genus, and the bivalves living in the
area would seem to me to be much too large for E. sulcidentata to handle.
Has anyone observed E. sulcidentata feeding?  If so, on what?  Radwin and
Wells (1968) attempted to determine food preferences for this species in
an aquarium but all the animals died without eating.  Any ideas?
Thanks,
