* An Arrow Crab (Stenorhynchus
seticornis) takes refuge in a Glassy Sponge (Callyspongia
plicifera). In the lower right corner is the arm of a
Brittlestar (Ophiothrix swensonii). Visible at the top of
the sponge is the Hydroid (Cnidoscyphus marginatus).
Sponges often harbor various sorts of marine creatures, for example, the
Barber Pole Shrimp (Stenopus hispidus) (1).
It is interesting that we have never seen Brittlestars in conjunction
with Callyspongia
plicifera, at least interior to the sponge. Little Cayman Island - Depth 45 feet or 14 meters |
