Polymastia crocea

Polymastia crocea is a species of sea sponge belonging to the family Polymastiidae. It is found in subtidal habitats below 6 m depth in the far north of the North Island of New Zealand.

This is a globular sponge up to 4 cm across or an encrusting sponge up to 7 cm across. This soft-textured sponge is very bright yellow outside and in with the surface covered in small papillae, some with pores, some without.
