REPTILIA: SQUAMATA: DIPLOGLOSSA: ANNIELLIDAE
The Anniellidae is a family of three described taxa
known only from coastal California, from near San Francisco south to central
Baja. They are all diminutive, thin, limbless burrowers found in loose dry
soils. They are similar enough to the Anguidae that some authors place them in
that larger family. However, anniellids lack an external ear opening or the
lateral fold that characterize many limbless anguids. The name "Anniella"
is derived from Latin and means "little worm."
These legless lizards have smooth, shiny scales and a
pointed snout, which gives them streamlining for ease in sub-soil locomotion.
The tail is much longer than the head and body length, and is easily lost. A
replacement can be regrown.
Legless lizards have a yellow belly, but differ greatly
in dorsal coloration. Females give birth to 1-6 live young in late summer.
