A pair of polyceridae nudibranch Nembrotha kubaryana moving across the base of the sea mound at the famous Steve's Bommie dive site in the Great Barrier Reef in Queensland, Australia.
(Nembrotha kubaryana) has many color variations including spots, thin lines and even alternate color spots. The red margin on the slug's foot is always present and is the best visual identifier.
Like most Nembrotha species, these nudibranchs are carnivorous and our known to be voracious predators primarily of small flatworms and other nudibranchs.
