Sponge Facts For Kids. Fun Information About Sponges

Sponges are the simplest animals and look more like plants than creatures. These fascinating invertebrates are found attached to rocks and coral in oceans all around the world. Sponges are designed with porous bodies full of tiny holes that let water flow through, bringing food and oxygen while removing waste.

There are over 5,000 species of sponges in many shapes, sizes, and colors. These animals have no organs, muscles, or nervous system, yet they filter thousands of gallons of water each day to catch tiny food particles. Sponges can regenerate from broken pieces and some species can live for thousands of years, making them among the longest-living animals on Earth!
