This is the upside down jellyfish—but this one is actually upside up! 😅
They are most often found with the flat body (called the bell) facing down and tentacles up.
This exposes algae, living within the jelly, to sunlight so they can photosynthesize— producing nutrients for the jelly!
Counter to most jellies, upside-downers don’t sting with tentacles but release mucus grenades with stinging cells that can inject venom into their prey.
Upside-downers are mainly found in coastal mangroves, one of the most threatened habitats on earth! 🌎
