4 New Legless Lizards Discovered In California
They're not snakes. One species lives right by LAX.
You always knew there was something creepy about LAX. Now, a pair of researchers has discovered four new species of legless lizards—technically not snakes—one of which lives underneath the dunes at the end of a runway at Los Angeles’s major airport. The others live in other sandy areas in California.

Although they look alike, legless lizards and snakes are only distantly related. If you trace their evolutionary history back far enough, snakes and other legless lizard species all descended from lizards, but after they split into different groups, the different groups each lost their legs independently. This means that while snakes are legless lizards, not all legless lizards are snakes.
Until now, only one non-snake legless lizard species was known to live in California, so the new discoveries make family reunions suddenly much more crowded. The two researchers who found the new lizards had searched for other species over the past 15 years, certain that there must be more than the Anniella pulchra.
The Los Angeles Times interviewed one of the discoverers, geologist James Parham of California State University in Fullerton, who described some of the differences between these new guys, which all belong to the genus Anniella, and true snakes:
‘Anniella can blink at you, but snakes can’t because they don’t have eyelids,’ said Parham, one of the authors of the paper.
They also don’t shed their skin in one piece like snakes do, and they move differently.
Snakes can coil up a lot more, and they are more slithery,’ Parham said. ‘Anniella tend to be more rigid.’
Fun. You can learn more about where to find the new Anniella—or how to avoid their preferred habitat, depending on your inclination—from Reuters and the Los Angeles Times. Both also have slideshows showing the new species, so you may judge whether they are cuter than snakes, as Parham told the Times.
