Sponge

Design

God designed the sponge with the ability to draw water into its body through tiny holes. It then filters the water for food and oxygen before pushing the water out again. Sponges pump remarkable amounts of water. Many sponges produce toxic chemicals that keep predators from eating them.

Features

• The sponge’s shape comes from a skeleton that is made up of tiny spicules of hard minerals located throughout its body.
• Sponges come in a variety of shapes such as tubes, spheres, and threads.
