Northern Australia: Box Jellyfish

6 of 12

There have been 70 fatal box jellyfish stings in Australia over the last century or so. And while most of the 19 species of box jellyfish
worldwide are venomous, the most lethal is Australia’s notorious Chironex
fleckeri
. Commonly found off the northern coast from November to May, they
have enough venom to kill 60 humans in three minutes flat. Tentacles can grow
up to 10 feet long, and just grazing one can cause near instant death.

Survival Tip: Swim with a full-body Lycra suit to protect
yourself against a sting. If stung elsewhere on your skin, immediately remove
tentacles with tweezers and douse the stung area in vinegar.

Safe Spotting: Dying box jellyfish will wash up on shore 9–10
days after the full moon. Their venom stays active, however, so wear shoes when
walking on the beach to glimpse these toxic creatures.
