seen? This large crab with typical spoon-tipped pincers
is sometimes seen in rocky or rubbly areas on our Southern shores.
Features: Body width 8-10cm. Body
oval, rather flat, with 4-5 blunt teeth on the edges of the shell.
Colours and patterns in a wide variety; basically brown or grey, sometimes
with dark patches or mottled. Pincers not very long, somewhat squat
with bumps on the 'elbows' and black spoon-shaped tips. These are
probably used to scrape off algae. The walking legs are fringed with
long hairs and end in pointed tips.
Sometimes confused with Smooth
spooner crab (Etisus laevimanus) which have pincers that
are longer, more slender and smooth (without bumps).
with bumpy elbows.
