DIET: Isopods eat plankton, algae, and the blood of host fish, crab, shrimp, lobsters and barnacles.
PREDATORS: The isopod is prey to fish, anemones, birds and worms.
FUN FACT: This isopod is related to the common backyard roly-poly. There are also several parasitic species of isopod, commonly known as ““tongue-biters”“ for their habit of nibbling off fishes’ tongues and attaching themselves to the floor of the host’s mouth.
