Good afternoon,
This picture is of our Boxer crab, aka pom-pom crab (Lybia tessellata) in our reef tank.
I rarely see this guy and in this picture we can't see his pom-poms
because he probably doesn't have any anemones.
From the web: "Boxer crabs feed sea anemones in exchange for defense
from danger — serving as a prominent example of symbiosis in the animal
kingdom. They reach about an inch in width. They are known as ‘pom-pom’ or
boxers crabs due to their unique presentation of sea anemones,
which live attached to the crab’s claws and are often
wielded similarly to ‘pom poms’ or boxing gloves."
Speaking of Boxers, we have two in our home as well as 2 other dogs. Barry on the left and Rocky on the right.
