The Colossal Nomura Jellyfish

Nomura jellyfish are colossal in size, weighing up to 450 lbs. and measuring 12’ in circumference. Nomura jellyfish directly follow and stalk their prey just as box jellyfish do, with a single Nomura jellyfish able to consume an entire Olympic swimming pool sized body of water filled with zooplankton within 24 hours.

Currently, it is unclear to scientists where Nomura jellyfish originate from
