Isopods and Amphipods
The primitive, minute crustaceans can be found everywhere, as commensals and as parasites on oysters, in sponges, and hydroid masses, crawling like little bugs over algae clumps, in oceanic, brackish and fresh water. Everything eats them.
Ar-1150 , Ligia exotica, a large, scavenging isopod that
scurries over wharf pilings.
Browses on seaweed cast up on the beach. Can reduce its high body temperature by evaporating water off body surface. Has been used in neurological research on activity of neurogenic hearts. Size: 2 – 4 cm.
Ar-1180 SKELETON SHRIMP, Caprella acutifrons, an amazing grotesque little amphipod that bends, flexes, and flips around hydroid colonies, scraping diatoms and debris from the branches and polyps with its hugh flat claws. The females carry their young in brood pouches. Skeleton shrimp make excellent live food for fish. They are shipped attached to the hydroid colonies on which they live. Size: 0.25 – 1.0 cm.
