Description
They are usually seen covered with sponge which they apply themselves. The carapace of a fully grown male is roughly 30 millimetres (1.2 in) long and slightly narrower than it is long.[1][2]
Inachus dorsettensis resembles the closely related species Inachus phalangium, but has more prominent spines on the carapace.[1] They molt, with the intermolting period being shorter the warmer the water they reside in is.[3]
Distribution
Scorpion spider crab is found along the east coast of the Atlantic Ocean from Norway to South Africa, and also in the Mediterranean Sea.[1]
