Looking inside corkscrew anemones



Corkscrew anemones are translucent.  Their name comes from their  corkscrew-like, whitish markings.  They don't get more than 6 or 7 inches across.  And they provide habitat for several shrimp species.  Often, we see a pair of red-and-white-banded antennae protruding beyond the tentacles.  The antennae belong to red snapping shrimp, which we rarely get more than a glimpse of.




However, today we were able to attract the attention of a curious red snapping shrimp, that seemed to be interested in cleaning our fingers.  The larger claw is the snapping claw, and when the claw snapped, we heard it (and felt it, when the claw was aimed at our fingers).  The snapping may deter intruders, and may also help the shrimp procure food.
