Puffball Sponge

Oceanapia sagittaria


Also known as Pink Puffball Sponge, Burrowing Sponge, Red Burrowing Sponge, Maiden's Fan and Red Maiden Fan Sponge. They feed on plankton and can grow to a length of about 10cm.


Found on shallow coral and rocky reefs with the stalk buried in the substrate and the cap about the size of a golf ball above is used for filtering food. This ball can also fall off, roll around the seabed, reattach or reform into another sponge. Widespread in the Western Central Pacific.


A violet-hued globe that looks like it's made of gossamer, attached to a slender tube. The base seems to be rooted in the sand. Spotted this curious-looking marine life at a depth of about 30 feet, at a dive site called Limao Reef, off the coast of Samal Island, Philippines.

@Gerardo - I don't know. I showed it to some of my friends and they couldn't identify it either.

@Leuba - I'd say it was about 2-3cm in diameter. Partially visible creature? Do you mean the one above it? That's a type of corallimorph, if I'm not mistaken.

@Nopayahnah - Thanks very much!
