Nameless Sponge (Haliclona innominata)

This species was described and – yes – also named thereby, in 1900; it is only known from the sea surrounding Christmas Island, Australia.

“Sponge incrusting; colour pale brown with a faint reddish tinge; texture soft and elastic.“

The species has never been found since its description and is now believed to be possibly extinct. [1]
