Fact Friday
Some species of parrotfish secrete a cocoon of mucus to sleep in at night. They tuck themselves into the branches of a coral and snooze, worry free. The mucus keeps predators and parasites from being able to sense their location. Check out this video!

Golden Jellyfish
These are no ordinary jellyfish. The golden jellyfish in Palau’s Jellyfish Lake move together in a daily migration that follows the sun from one side of this marine lake to the other. Just like coral, these jellyfish have symbiotic algae, called zooxanthellae, living in their tissues. The zooxanthellae photosynthesize and then share nutrients with the jellyfish, which it needs to survive. Once the sun goes down, the jellyfish migrate back to the other side of the lake where they begin the cycle all over again the next morning.
