Description
Also known as Ball Sponge, Cake Garlic Sponge, Cake Sponge, Marine Sponge, Siliceous Sponge.
Found over hard bottoms, in seagrass beds, around mangroves, and shallow reefs. Varies in colour, grey or white with black inside.
They feed on plankton.
Length - 46cm
Depth - 5-25m
Widespread Western Atlantic, Caribbean
Sponges come in a range of sizes from minuscule encrusting species under rocks to massive sponges which can be up to one and half metres high.
They are able to filter many litres of sea water every few seconds.
Sponges can exude highly toxic chemicals and so have very few predators apart from nudibranchs, sea stars, sea urchins and umbrella shell.
Their colour can vary if growing in the light or when growing in the shade. (edit)
