Velvet Swimming Crab

Necora puber

Sighting evidence at Carnota Wreck, Galicia

The most pugnacious crab in Galician waters, velvet swimming crabs raise their claws at approaching divers and hold their ground on the wreck surface rather than retreating. They are highly valued commercially and their presence in numbers on this relatively undisturbed wreck is a sign of healthy local populations away from heavily fished ground.
