Ophiclinus antarcticus, the Adelaide snake blenny (or Dusky snake blenny[1]), is a species of clinid found in the coastal waters of southern Australia.

It can reach a maximum length of 14 centimetres (5.5 in) TL.

[2] It often has dark blotches and speckles on its body and fins, with a series of large white blotches along the midside, dorsal-fin base and just above the anal-fin base.

It also has several dark stripes that often radiate from its eyes and dark brown markings on the lips and lower side of the head.
