Idotea metallica
This record describes Idotea metallica (species). Recorded family: Idoteidae. Recorded order: Isopoda.
Identification and Appearance
Among New England valviferan isopods (and probably among other regional valviferan fauna as well), can be identified by the blunt, squared off shape of the telson. Also distinctive is the metallic blue coloration.
Classification
Habitat and Range
Habitat
Pelagic. Doesn't breed nearshore due to competition from I. balthica and other species. Can drift ashore with seaweed it's attached to.

About Isopods: the wider group
Order-level background for Isopoda, the group containing Idotea metallica. Species-specific details appear above.
Group overview
Isopoda includes ~10,000 described species of woodlice, pill bugs, and sea slaters. Woodlice are the only crustaceans to have fully adapted to life on land. Pill bugs (roly-polies) can roll into a perfect ball for defense.
Ecological role of the group
Woodlice are critical soil decomposers, breaking down dead plant material and recycling calcium and other nutrients. They breathe through gill-like structures and require moist environments. Giant deep-sea isopods (Bathynomus) can grow up to 50cm long.
Economic and practical significance of the group
Woodlice are generally beneficial in gardens as decomposers, though they can occasionally damage seedlings and soft fruits in large numbers.
Recorded sources for this group: Soil ecology research, marine biology. Imported estimates may describe particular regions or reporting periods.
