WhyReef - Lifestyle
Many people think lemon sponges are plants, but they’re actually simple animals, lacking heads or guts! They live in large groups and use tiny tails to create water currents. By making water flow in and out of their cells, they trap any particles from the water and eat them. That’s why they’re called filter feeders.
You can find them growing on rocks or dead coral on the reef. Because they have toxic chemicals in their bodies, not many animals can eat them.
