Description

The Mitotic stingaree is a stingaree (Urolophidae) from shallow sandy and seagrass water of the waters around Australia. The species grows to about 40 cm and has a round to oval, flat disc and a fairly short tail with a small fin fold at the end. Half-buried it searches for worms, crustaceans and molluscs. In its tail it carries one or more venomous, serrated spines that give a very painful wound; it stings only in defence when touched or stepped on.

Is the Mitotic stingaree dangerous to humans?

The Mitotic stingaree is venomous — handle spines with care and seek medical help after a sting if needed. A sting from the tail's venomous spine is very painful: rinse the wound, remove any visible spine fragments and immerse the part for 30-90 minutes in water as hot as can be tolerated (about 45 C). Because of the risk of a deep wound and retained tissue, medical assessment is advised; update tetanus protection and watch for signs of infection.
