fiddler crab Uca annulipes Family Ocypodidae updated Mar 09 Where seen? This small crab with an enlarged pincer that is smooth is sometimes seen on some of our shores. Sandy, silty shores near the low water mark, often near mangroves. Features: Body width 1.5-2cm. The male fiddler crab's enlarged pincer has a ridge of bumps on inside or the 'palm' of the pincer. The outer side is smooth and does not have a triangular depression. The movable upper finger extends past the immobile lower finger. The enlarged pincer is usually pink, sometimes nearly white. The body is often black with blue or white stripes. |
