You said there were 11 species to catch, but I got twelve. Or possibly I'm missing one if the three kinds of bison are all one species. Just to check I tried the nurse but although you can sedate them you can't thereafter push them and the dialogue doesn't change. This is probably a good thing. For the record, I caught frog, octo, mosquito, clawfly, beetle, snake, raptor, sail lizard, butterfly, bison, bison bull, bison calf. If there's another one I don't have any idea what it might be. I tried pushing melons just in case, but I can't seem to do it even with them fully sedated and rocks just kill them like anything else.
It's neat how much of the ecosystem is present in the game. I saw that octos like to mirror your movement and can hide (poorly) in water, frogs can hide well in water and are nocturnal, raptors live in trees, Bison form family groups with one bull and protect their calves, Butterflies like flowers, Beetles eat melons, Sail lizards eat Beetles but are scared of pretty much everything else, Clawflies are friendly and non-aggressive and only mosquitoes eat them, Mosquitoes attack anything that moves, which usually gets them squashed, and snakes hide in grass and ambush prey but leave it alone if the initial attack fails.
