We see Vase Sponges all the time when we dive.

Most of the time they are just that, a vase sponge doing the things that a vase sponge does.... which is not much other than look pretty and pink.

But we have gotten into the habit a having a look inside.... because sometimes there is a party going on.

This party was attended by an Arrowcrab and a Gobe.
