A group of biologists working in Saskatchewan's Grasslands National Park are trying to save one of Canada's rarest and perhaps strangest creatures — the greater short-horned lizard.

This lizard, which can be found anywhere between New Mexico and southwestern Alberta, has a rather unique and strange defense mechanism. It shoots its own blood from its eyes to ward off an attacker.
The lizard has been considered endangered on Canada's Species At Risk list since 2007, mainly due to habitat loss from "ongoing oil and gas development, proliferation of roads, proposed mineral development, and an increased human presence."
