21. Crown Jellyfish
This unusual jellyfish is likely part of a genus of jellyfish called Atolla, which can only survive at high depths in the ocean. It has long tentacles that it drags behind itself in order to catch small prey swimming around in the waters. They mostly feed on zooplankton, which are microscopic animals.
Crown jellyfish are capable of bioluminescence and are lit up when they’re touched. Left undisturbed, they’re quite transparent. If they’re attacked, they can use their light to startle and mislead predators as to what’s going on, causing confusion. Otherwise, the light is used to attract prey.
