Box jellyfish
In Australia (mainly northern; however, box jellyfish can live in subtropical waters as far south as Sydney, with "Carybdea marsupialis" being recorded as far south as Bermagui, Sapphire Coast) the highest risk period for the box jellyfish is between October and May, but stings and specimens have been reported all months of the year. Similarly, the highest risk conditions are those with calm water and a light, onshore breeze; however, stings and specimens have been reported in all conditions.

The Jellyfish (vocal effects by Tom Kenny) are wild animals who reside in Jellyfish Fields, a meadow in Bikini Bottom, and have a strong affinity for music. Within the series, jellyfish behave like sentient insects, squirt jelly, buzz and swarm like bees, and can sting their enemies with electric shocks that leave painful welts.
