Environment: milieu / climate zone / depth range / distribution range
Ecology
Benthic; depth range 0 - 580 m (Ref. 3113). Polar
Northeast Atlantic and the Antarctic.
Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm Max length : 9.0 cm TL male/unsexed; (Ref. 8360)
Depth range based on a locality (Ref. 3113); to be replaced with a better reference. High motile and eurybathic. Common in intertidal and subtidal areas. Associated with epizoic bryozoans; larger isopods had significantly more and diverse bryozoan colonies. Epibiosis, in this relationship, appears to be advantageous (Ref. 117942).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Members of the order Isopoda are mostly gonochoric. Mating behavior: Mating usually occurs before and sometimes during the parturial molt. Sperm transfer is indirect. Life cycle: Eggs are brooded in the marsupium, which later hatch into manca postlarva before developing into adults.
