Shiny Bait Crab

Davusia glabra

The Shiny Bait Crab, also known as the Sowrie or Sourie crab, is the only species in the genus Davusia. It inhabits the rocky ocean shores along the eastern coast of Australia, from southern Queensland to Victoria. The crab is typically found around the low tide zone, residing in crevices, rock pools, and on rock platforms. Its carapace is distinctively smooth and hairless, measuring approximately 30-40 mm across. The crab's grey to fawn coloration is interspersed with tiny green spots, giving it a subtle greenish hue. The carapace is slightly wider than it is long, featuring three distinct spines on each edge, which can help divers identify it from similar species. The Shiny Bait Crab's habitat is primarily rocky shores, which provides it with ample crevices and rock pools to hide in. This environment supports its crevice-dwelling behavior, allowing it to remain concealed from predators and the elements. Divers encountering the Shiny Bait Crab will likely find it in shallow, rocky areas during low tide. Observing this crab can be a unique experience, as its cryptic coloration allows it to blend seamlessly with its surroundings.
