Maroon stone crab
Menippe rumphii
Family Menippidae
updated Dec 2016

Where seen? This sturdy crab is seen in rocky and rubbly areas on our Northern shores. Elsewhere, it is found in sandy-muddy areas usually under rocks.

Features: Body width to about 9cm. Large oval body, edge smooth with four blunt points or 'teeth'. Between the eyes are four tiny bumps arranged in a square. Reddish to pinkish brown and maroon in adults; young crabs maroon to reddish brown, with longitudinal white stripes. Large pincers smooth (no pimples) with black tips. One pincer slightly larger with a large molar-like tooth at the base of the finger. Walking legs not very hairy. Its eyes are all red without any green, unlike
the very similar looking Stone crab (Myomenippe hardwickii).

Sometimes mistaken for the Stone crab (Myomenippe hardwickii) and Red egg crab (Atergatis integerrimus).
Here's more on how to tell apart big crabs with big pincers seen on our rocky shores and coral rubble.
