New Mexico Whiptail vs Marbled Whiptail
The New Mexico whiptail and the marbled whiptail share the same slender body and desert habitat, but one reproduces without any males at all while the other represents the ordinary, sexually reproducing whiptail lifestyle found across most of the genus.

New Mexico Whiptail vs Marbled Whiptail: common questions
Why does the New Mexico whiptail have no males?
This species arose from a single ancient hybridisation event between two related, sexually reproducing whiptail species, and the resulting hybrid female was able to reproduce by parthenogenesis, passing her exact genome to every descendant since, meaning the entire species today is an all-female clone lineage that has never needed males to persist.
Is the marbled whiptail related to the New Mexico whiptail?
They belong to the same genus and share a similar desert lifestyle, but the marbled whiptail is a normal, sexually reproducing species rather than one of the parent species directly involved in the New Mexico whiptail's specific founding hybridisation event, though it illustrates the ordinary bisexual whiptail lifestyle that species like the New Mexico whiptail diverged from.
Which whiptail handles extreme heat better?
The marbled whiptail is especially notable for tolerating some of the hottest, most sparsely vegetated desert flats in North America, remaining active during the hottest parts of the day in the Chihuahuan Desert when many other lizards, potentially including the New Mexico whiptail, have already retreated underground.
