Lebbeus grandimanus (Brazhnikov, 1907)
Common name(s): Candy stripe shrimp, Clown shrimp
|Synonyms: Lebbeus grandimana|
Family Hippolytidae (broken-back shrimp) (now in family Thoridae)
|Lebbeus grandimanus, about 2 cm long, found on an anemone at about 10 m depth near Northwest Island|

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. Sometimes parasitized by the isopod gill chamber parasite Bopyroides hippolytes (photos).

This closeup of the anterior end shows the chelae.
This individual, found on the column of a Cribrinopsis fernaldi anemone in 2014, has a parasitic isopod Bopyroides hippolytes in the gill chamber. Animal total length = 3 to 3.5 cm.

|Dorsal view.||Lateral view. The main thing that can be seen is the large mass of eggs the female is carrying.|
In this view of the head, the long rostrum (extending well beyond eye) and the single supraorbital spine just above the eye can be seen.
This view shows the posterolateral border of the carapace (top left) and the ventral margin of the pleuron of each of the five abdominal segments (counting around clockwise to the center bottom). Note that the ventral margins of pleura 2 and 3 (and also of 1 and 4) are rounded, as is characteristic of this species.
