Hobson's Survival Choice

Why are some animals more endangered than others? Is it loss of habitat, over hunting, or perhaps it's a more intrinsic property like an animal's cuteness, scariness or tastiness?

In order to explore this last question, I spent $40 and submitted a survey to Amazon's Mechanical Turk. This survey consisted of 300 randomly selected animal pictures spanning over three different conservation statuses: Least Concerned, Threatened, and Endangered. After each image was rated multiple times, I compiled this following chart:

So, in order to assure your species survival, I would definitely recommend investing in big-round-eye plastic surgery or (at the very least) make sure you taste good next to a side of potatoes.
