It is "the most unusual" of the genera in the subfamily Eumedoninae, with long spines projecting from the body, and a distinctive pattern of stripes across the exoskeleton. Taxonomy and distribution The genus was thought to be monotypic for a long time, but in 1999, Peter Ng & Diana Chia recognised two additional species, bringing the total number to three. * ''Zebrida adamsii'' is widespread in the Indian Ocean and western Pacific Ocean, from Japan to Australia. * ''Zebrida brevicarinata'' is only known from Western Australia. * ''Zebrida longispina'' is only known from Western Australia.

The carapace and limbs are smooth and hairless and are adorned with long spines. The colour is pink with dark, reddish-brown vertical stripes.
