Davusia glabra, commonly called the shiny bait crab,[1]Sowrie crab[2] or Sourie crab is the sole species of crab in the genus Davusia.[3] It lives around the low tide area on rocky ocean shores on the eastern coast of Australia (southern Queensland to Victoria), in crevices and rock pools and on rock platforms.[1] Its distribution is stated differently in different sources; some have described the crab's habitat as from Queensland to as far south as the NSW-Victorian border,[2] while others have stated it can be found as far south as Wilson's Promontory (Southern Victoria).[4] Its carapace is grey to fawn-colored with very small green spots, resulting in Davusia glabra having a greenish appearance.[2] The width of the carapace is around 30-40 mm across[1] and is smooth without hair, slightly wider than long, with 3 distinct spines at each edge.[2]
Plagusia glabra is a synonym of Davusia glabra,.[3] The species was placed in the new Davusia genus in 2007[5] due to differences in morphology from other species in Plagusia.
