Box jellyfish are most abundant off the northern coast of Australia between November and April. Some beaches remain closed during these times for the safety of the public, according to Oceana.org.
The sting of an Australian box jellyfish can be lethal to humans. It is considered to be the most venomous marine animal, according to the National Oceanic and Atmospheric Association. Symptoms of a box jellyfish sting include paralysis, heart attacks and loss of consciousness.
