Rostanga crawfordi is a species of sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Discodorididae. Originally described as Discodoris crawfordi, it was redescribed by Rudman & Avern as Rostanga australis. The two names were synonymised by Dayrat.[3] It was named after Tom Crawford, an Australian malacologist who compiled an extensive collection of Opisthobranchia prior to his death in 1966 at the age of 22.[4]
