Behaviour

Queensnakes hunt crayfish under stream rocks, taking them just after they have moulted, while their shells are soft and their claws harmless.

Why they matter

They need clean water and healthy crayfish populations, so their presence says a lot about a stream's health.

Size at birth — About 18 to 23 cm

Living around people

  • It is harmless; keeping silt out of streams keeps its crayfish.

Misconceptions

  • Water snakes eat all the fish. Queensnakes eat crayfish, not fish.
