Flower Hat Jellyハナガサクラゲ
Olindias formosusNE— Not Evaluated
The flower hat jelly is a striking jellyfish from the northwestern Pacific, named for its coiled, fluorescent-tipped tentacles that resemble a flower-shaped hat. It rests on the seafloor by day and rises to hunt small fish at night, delivering a sting that is painful but not considered life-threatening under normal circumstances.
