Description: As
with other hippolytid
shrimp, this species has no exopodites
on its pereopods,
the carpus
of pereopod
2 is divided into 3-7 subunits (articles, a "multiarticulated carpus"),
and a rostrum
is present but if it has dorsal spines they are not movable. Lebbeus
grandimanus has 7 articles
on the carpus
of its 2nd pereopod.
It has one supraorbital
spine. It has no exopodite
on maxilliped
3, the rostrum
is longer than the eye, the pleura
of abdominal segments 2 and 3 are rounded, and leg 3 has no epipodite.
The body is translucent and covered with bright yellow, blue, and red
bands.
Length to 4.5 cm.
How to Distinguish from
Similar Species:
The bright colored bands on this shrimp are distinctive.
Geographical
Range: Aleutian Islands,
Alaska to Puget Sound
Depth Range:
6-180 m
Habitat: Often
lives on rocks in association
with the anemone Cribrinopsis
fernaldi, Urticina
crassicornis, U.
piscivora, or U. columbiana.
Most commonly associated
with Cribrinopsis
(photo).
Biology/Natural History:
Often lives
on rocks in association with the above anemones, remaining on the base
of the column or foraging around on the oral disk picking up
scraps.
The shrimp seems immune to the anemone's nematocysts. They have been
found
in the guts of Pacific Halibut off Alaska.
