The flower hat jelly (Olindias formosa) is a rare species of jellyfish occurring primarily in waters off Brazil, Argentina, and southern Japan. Characterized by lustrous tentacles that coil and adhere to its rim when not in use, the flower hat jelly’s bell is translucent and pinstriped with opaque bands, making it easily recognizable.

The flower hat jelly can grow to be about 15cm (6 inches) in diameter. Its sting is painful but non-lethal to humans. Its diet consists mostly of small fish.
