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.

How is this calculated?

Sighting evidence is compiled from iNaturalist observation records within a set proximity radius, filtered for quality-grade observations. “Last confirmed” is the date of the most recent research-grade record. Record count covers a rolling 24-month window. Confidence reflects record count, recency, and consistency of seasonal signal.
