Wonambi was a madtsoiid snake, a very old snake group unrelated to Australia’s living pythons.

Wonambi was probably non-venomous and killed prey by wrapping around it and squeezing.

Kid Decode: No venom drama. This hunter used muscle and patience.

Compared with some modern big snakes, Wonambi had a relatively small skull, which may have limited the size of prey it could swallow.

6. It Was an Ambush Predator

Scientists think Wonambi may have waited in cover and attacked animals that came close.

Wonambi shared Pleistocene Australia with animals such as Thylacoleo, Diprotodon, giant birds, and giant lizards.

Kid Decode: Ancient Australia had a creature roster with no chill whatsoever.

Baby snakes are often called hatchlings because they hatch from eggs, so baby Wonambis can be called hatchlings too.

Wonambi disappeared during the Late Pleistocene, around the time many Australian megafauna vanished.
