🦎🐊Happy ! 🌎 This global holiday is a good time to appreciate the amazing adaptations of New Mexico’s lizards and the specialized care our hospital has provided lizard patients over the years. The reasons that lizards are brought to us are as diverse as the nearly 50 species found in New Mexico. The most common injuries to lizards are caused by cats or dogs.
Caudal autotomy, or tail loss, is one adaptation that some lizards have to escape predators. This is a last resort, though, and costs a great deal of energy to regrow, can weaken their immune system, and cause them to lose social status among their companions.
Like all reptiles, lizards are ectotherms, meaning their body temperature is reliant on their surrounding environment. In the winter, we sometimes receive lizards who are hypothermic or their brumation has been interrupted. However, rehabilitating lizards requires more time than mammals or birds because they have a slower metabolism, which means a longer recovery period.
Two resident lizards at NMWC on the Education side are Canyon the Collared Lizard and Mojave the Common Chuckwalla. Both were hatched and raised in human care to serve as educational ambassadors. In the wild, Collared Lizards can run extremely fast to avoid predators, while the Chuckwalla does the opposite and impersonates a rock. They can inflate their bodies with extra air to puff up and wedge themselves in a crevice just out of the reach of a predator.
Ten lizards are listed as Species of Greatest Conservation Need in New Mexico. They are vulnerable to climate change and habitat loss, plus the aforementioned domesticated animals that are not their natural predators. Simple steps you can take to help our local lizards include keeping your pets indoors or leashed. Also, keep us in mind if you see a lizard that needs help. Give us a call at 505-753-9505.
