How to Distinguish from Similar Species: We often catch this species in the same deep San Juan Channel otter trawls as Paracrangon echinata. The two species look superficially similar but Paracrangon has only 4 walking legs, is not as strongly red, has a longer rostrum, and typically assumes a defensive cataleptic posture when threatened. Several other Lebbeus species have rounded ends on the pleura of abdominal segments 2 and 3.
Geographical Range: Circumboreal. Bering Sea to Puget Sound in our area.
Depth Range: Very low intertidal (juveniles) to 518 m
Habitat: Soft bottoms with sand, gravel, and shells

Lebbeus groenlandicus sometimes assumes this cataleptic posture when disturbed, but seems less prone to do so than is Paracrangon echinata.
