Chorilia longipes

Longhorn decorator crab:

Longhorn decorator crab (Chorilia longipes): The longhorn decorator crab resembles the common decorator crab (Oregonia gracilis) in general shape. The longhorn decorator crab is only seen in deeper water, usually below 50 meters, while O. gracilis may be common in the intertidal and shallow subtidal. C. longipes, despite its common name, does not decorate (although sponges, bryozoans, etc. may settle on the carapace). One key feature to separate these is that O. gracilis has a long, narrow tooth behind each eye which is lacking in C. longipes. The legs and claws of C. longipes are often red-orange with white banding (especially towards the fingers of the claws). These are fairly commonly brought up in shrimp pots.
