Aaptos papillata is a species of sea sponge belonging to the family Suberitidae.

It is native to the northeastern Atlantic Ocean, the English Channel and the Mediterranean Sea.

Aaptos papillata is a massive sponge growing in a domed shape, the smooth velvety surface being densely covered in small, low nipples.

The interior is creamy-pink in the middle and yellowish-ochre near the surface, which is often obscured by sand and shell fragments.

It feeds on bacteria and small planktonic particles not exceeding three microns in diameter.
