Why is the yellow spotted lizard in holes name odd?

From the text:

Actually, it is kind of odd that scientists named the lizard after its yellow spots. Each lizard has exactly eleven yellow spots, but the spots are hard to see on its yellow-green body. The lizard is from six to ten inches long and has big red eyes. In truth, its eyes are yellow, and it is the skin around the eyes which is red, but everyone always speaks of its red eyes. It also has black teeth and a milky white tongue. Looking at one, you would have thought that it should have been named a "red-eyed" lizard, or a "black-toothed" lizard, or perhaps a "white-tongued" lizard.
