Four new species of legless lizards have been added to the one previously known member of the group Anniella, reports the journal Breviora.
From the LA Times:
Anniella are pretty small animals, about as thick as a pencil and rarely more than 8 inches long. They spend their lives wiggling beneath loose, sandy soil, snacking on bugs and larvae.
They don’t move fast or far, and the researchers say they may spend their whole lives in an area about the size of your dining room table.
Aside from that, scientists still don’t know much about them.
“They are one of the most poorly studied reptiles in California,” [Cal State Fullerton researcher James] Parham said. “Because they live under the sand, you can’t see what they are doing, and you can’t even do a mark-and-recapture because you can’t reliably capture these things.”
Parham and his coauthor Theodore Papenfuss, a herpetologist with the UC Berkeley Museum of Vertebrate Zoology, have been scouring the state for legless lizards for 15 years. When they began their research, only one type of legless lizard was known to live in California.
One of the four newly identified species of Anniella, the Southern California legless lizard, was found under some dead leaves in dunes at the west end of Los Angeles International Airport.
The Bakersfield legless lizard was found in three vacant lots in downtown Bakersfield.
The southern Sierra legless lizard was spotted in three dry canyons on the edge of the Mojave Desert, and the Temblor legless lizard was found in the oil fields around the city of Taft, on the southwestern edge of the San Joaquin Valley.
To find these lizards, the scientists scattered 2,000 pieces of cardboard and plywood throughout the state to create moist, cool areas, which appeal to the lizards. Then they returned months later to see if any of the lizards had shown up.
