I am no zoologist but aside from the bipedal sort I think it is 0 species.

Carl didn’t say “animal species” though. It’s our plants that will really get you! So the answer is probably 2? Tutu (Coriaria arborea) and Ongaonga (Urtica ferox).

I suspect the "on" is somewhat load bearing here, given some of the venomous and/or highly toothed sea creatures.
