Subject: Live Animal | Type: Photo | Life Stages And Gender: Adult/Sexually Mature

Description: Isopoda Aega sp., possibly Aega bicarinata Leach, 1818. This specimen was caught using a specimen collector. This particular family of Isopoda, the Aegidae, are temporary parasites on marine fishes. They engorge themselves with food (presumably blood), from their hosts, then dislodge and sit on the bottom to digest their meal. The specimen seen here is about 5 cm long from head to tail end. Item Type: Image Title: Aega sp. Copyright: Serpent project Species: Aega sp. Behaviour: Probably a temporary parasite, feeding on blood of fish host. The anterior first 3 pairs of pereiopods are hooked to hold on to the host whereas the rest of the pereipods are 'walking legs'.
