Herpetofauna: One Life's List

Aspidoscelis laredoensis
Laredo Striped Whiptail

Santa Ana NWF, Hidalgo Co., Texas
February 24, 1996

I observed several of these whiptails on the sandy banks high above the Rio Grande, but did not have my camera with me that day.  This species is unique in being unisexual - no males, only females, reproducing parthenogenically.
