Alternate Animals If Sequels Were Expanded to Other Continents

Easterns, yes. I think they're the most venomous, closely followed by the eastern "King" brown. The browns are bigger (at least a metre long, I've seen ones that get up to 1.5m) and have a stronger bite, but they're not quite as venomous. Not that it matters, they'll both kill you dead.
Number 1 is some kind of sea snake.

This topic is actually really interesting
~BTW, snow leopards aren't THAT much smaller than a tiger. A flying squirrel or gerbil stands little chance defeating one.

Indeed. It really would come down to how much of reality one is willing to bend in order to make such a scenario more plausible.

Also, welcome to the forum, Niki Redwood! If you post in the Introduction Topic in the Front Lawns, you can be more properly greeted.
