Common Clownfish

Clownfish are famous for their symbiotic relationship with anemones. Anemones, which are related to jellyfish, can sting animals that touch their tentacles. However, did you know that clownfish have a special protective layer of slime that protects them from being stung by anemones? The anemone, therefore, inadvertently protects the clownfish from other species that would otherwise try to prey on them.
