The RSPCA has launched an appeal to trace the owner of the non-venomous snake.

That said, it's easy to confuse a non-venomous snake with a venomous species, or vice versa.

Despite the size of the snake, the African Rock Python is a non-venomous snake of sub-Saharan Africa.

She knew at a glance a venomous from a non-venomous snake, an edible from an inedible nut.

Experts say the non-venomous snake is not part of New Caledonia's fauna and must have been introduced either illegally or by accident.
