Stingrays
There are many different kinds of stingrays in Australian waters. They usually swim and feed on the bottom of the sea. Accidents can happen if people stand on them or try to pick them up.
Stingrays have a sting on their tail. These stings have poison on them. If someone is stung the wound can easily become infected.
Treatment:
Put a plastic bag filled with ice and water on the sting and see a doctor.
