Scientists discover new legless lizard species in California
California
scientists have discovered four species of legless lizards hidden in
unlikely habitats among central valley oil derricks, sand dunes at the
end of a Los Angeles airport runway and other arid and desolate spaces.
The findings, announced in a
publication of the Museum of Comparative Zoology at Harvard University
this week, brings the number of known snake-like lizard species living
in California up from one to five.
"The
main thing this is showing is that right here in California ... there
is actual natural animal diversity that we don't know about yet," said
Theodore Papenfuss, a reptile and amphibian expert with the University
of California at Berkeley's Museum of Vertebrate Zoology.
Papenfuss
and geologist James Parham from the California State University
Fullerton led the research, spending 15 years searching the state for
the slithering creatures, their quest fueled by a hunch that at least
one relative of California's legless lizard species, the Anniella
pulchra, existed nearby.
One of the
research team's discoveries was in the protected El Segundo Dunes that
butt up against the end of a Los Angeles International Airport runway.
The yellow-bellied creature was named A. stebbinsi, after herpetologist
Robert C. Stebbins, who studied natural life in a local mountain range.
The
three other newly identified species were found in the San Joaquin
Valley, over 200 miles to the north, where they likely lived for
millions of years, Papenfuss and Parham's research showed.
The
silver-bellied A. alexanderae was found in the oilfields near the city
of Taft, the A. campi, with a yellow underside, was found in three
canyons at the outskirts of the Mojave Desert, and the purple-stomached
A. grinnelli, was discovered in a handful of vacant lots in downtown
Bakersfield, a city of 352,000.
The
animals, named after notable UC Berkeley scientists, were distinguished
from other similar identified species using color patterns, number and
arrangement of scales and vertebrae, and genetic testing.
All
had been collected before and preserved in museums and laboratories,
but their distinctive markings and genetic makeup was never examined,
and they were thought to have all belonged to the same group as Anniella
pulchra, Papenfuss said.
The
research team is in discussions the California Department of Fish and
Wildlife to determine if the newfound lizards require special
protections, Papenfuss said.
