Dendrogaster antarctica is an endoparasitic ascothoracid barnacle of Dendrogastridae that parasitizes on the common Antarctica cushion star, Odontaster validus.[2] It has been found in several sites in Antarctica and was originally discovered by Mark J. Grygier in 1980.[3] He then released an article in 1987 explaining the characteristics of a female member of the species.[4] It was confirmed as an official species in 2003.[5]

It has extremely small sperm. Their heads are 6–7 μm, long, The midpiece is as long as the head, and tapers to a flagellum 45–50 μm long. This sperm is the most primitive yet found in crustacea.[6]
