Dendrilla cactos

An encrusting sponge common on jetty pylons, this species is usually bright pink in colour, but can range range from whitish or pale pink as well. It is spiky in appearnace, with large pointed papillae. It is similar in appearance to a number of sponge species, including Darwinella australienses, Dendrilla rosea, and the Dendrilla sponge previously known as Aplysilla rosea. However, it differs from these species by its more prominent papillae, and lack of obvious osculae.
