Researchers in Hong Kong recently discovered a new species of box jellyfish living in a brackish shrimp pond - the first-ever box jellyfish to be found in Chinese waters. Named Tripedalia maipoensis after the Mai Po Nature Reserve in Hong Kong where the jellies were found, these small, cube-shaped jellyfish are completely transparent and colorless. Stemming from their bells, they have 12 tentacles that end in tiny, paddle-like structures, allowing them to travel more quickly through water than most other jellyfish.
