General Notes and Observations: Locations, abundances, unusual behaviors:
Though there are many bumps and small spines on this species' carapace, it does not have the prominent, laterally-directed spines behind the eyes that Oregonia gracilis has.
The long spines which make up the rostrum can be clearly seen from below
|Chorilia longipes has long, thin legs and chelae. Both of its chelae are striped orange-red and white on both the inside and outside.|
