Sponge

Project Description

Sponge

Phylum Porifera

Range/Geographical Distribution: Worldwide.

Habitat: Most brackish and marine habitats.

Description: Porous body with variable shapes and colors.

Size:  Variable, colonies are usually less than two feet.

Food: Suspension feeder; eats plankton.

Breeding: Reproduce asexually by budding.  Sexual reproduction occurs when sponges release male gametes into the water and they are captured by neighboring sponges, which use them to fertilize eggs.

Predators: Sea turtles, crabs, mollusks, fish, and worms.

Conservation Status: No legal status.

Interesting Facts: There are 5000 species of sponges worldwide and most are marine.  Sponges have skeletons made of collagen and either calcareous or siliceous spicules.  They can contain toxic substances and other animals take advantage of this by placing sponges on their bodies.

On the Coast: Sponges are common along Georgia’s coast and pieces frequently wash up on the beach.
