Fact Friday
Some cnidarians switch between a polyp and a medusa body form. Corals and anemones only have the polyp stage. Jellyfish, as we think of them, are in the medusa stage, but they have a polyp stage when they are juveniles. Hydrozoans have the opposite: their adult form is a polyp, but they have a juvenile medusa stage.

Longfin Spadefish
Nothing to see here! The longfin spadefish has a unique tactic to avoid predators. When they are young, divers have observed them mimicking floating leaves. They lie on their side and drift back and forth in the waves to avoid being eaten. That’s “batty” behavior!
