Blue-Pincher Crab

Description:

Brownish carapace and blue claws with red tips.

Habitat:

Common in muddy bays and harbors. Picture taken at Ala Wai Canal near McCully bridge. Noticed a large amount of these crabs appeared that I had not seen here before.

Notes:

I'm guessing at the exact species, and guessing the more brownish carapace is die to algae and pollution that is rampant in the canal. So if someone knows that I have misidentified please let me know.
