Upside-down jellyfish are found in warm coastal waters—such as mangroves, bays and lagoons—around the world.

The venom of some box jellyfish species is considered to be among the most powerful in the world.

While jellyfish are fairly common in the area, such large congregations are quite unusual at this time of year.

Some species of jellyfish are able to grow back tissue that has been lost.

Jellyfish larvae can get trapped in bathing suits and sting the skin.

Surf Life Saving Queensland described the stings as an "epidemic."

Sea lice are not actually lice; they are the larvae of jellyfish and sea anemones. 

Officials cleared up the gelatinous creatures with cleaning boats and even tractors.
