Sponges are an important animal for marine and freshwater ecology and represent a rich animal diversity found throughout the world, from tropical climates to the arctic poles. For evolutionary biologists, they also present an interesting animal for comparative study because they are simple filter feeders, and lack nervous, digestive or circulatory systems, suggesting that they diverged early from other animals.
