Description

Aaptos papillata is a massive sponge growing in a domed shape, the smooth velvety surface being densely covered in small, low nipples. The oscula through which water exits are small and few in number. The colour of this sponge is pink flushed with purple, the nipples being paler. The interior is creamy-pink in the middle and yellowish-ochre near the surface, which is often obscured by sand and shell fragments. The consistency is firm but elastic.[2]

Biology

Like most species of sponge, Aaptos papillata is a filter feeder. Water passes in through pores, food particles are filtered out and the water passes out through the oscula. It feeds on bacteria and small planktonic particles not exceeding three microns in diameter. Its means of reproduction have not been studied but it is likely to be similar to other members of its family. Sponges are generally hermaphrodite; sexual reproduction is by the release of gametes into the water column; asexual reproduction may be by budding, or by detachment of fragments of sponge.[2]

gollark: I cannot confirm this.
gollark: It's a good command. I even improved it to use a multinomial distribution.
gollark: Epicbot was of course prepared for your pathetic countermeasures.
