Bipes biporus is unique among the other members of the Bipedidae in that it has an enhanced capacity for thermoregulation.
These lizards would seem to have at least some ability to adapt to changing environments.

Journal of Herpetology Once sexually mature, females only reproduce, at most, once every other year. In other words, Central and South America. Juveniles are mainly pink in color, turning white as they mature. Bipes biporusp. Bipes biporus plays a role in the ecosystem as a predator on terrestrial or burrowing invertebrates. You can help Wikipedia by expanding it. Grismer, ; Papenfuss, Other Physical Features ectothermic bilateral symmetry Sexual Dimorphism sexes alike Range length high mm 9.

Whether or not buporus difference was due to sampling bias or if the ibporus sex ratio was actually skewed could not be determined. The species only breeds underground. Their skin is closely segmented to give a corrugated appearance, and like earthworms, their underground movement is by peristalsis of the segments. Papenfuss, Known Predators Serpentes Snakes Ecosystem Roles Bipes biporus plays a role in the ecosystem as a predator on terrestrial or burrowing invertebrates.

However, this unique ear structure may be important for locating prey above the surface. Connect with us Help us improve the site by taking our survey.
This species is oviparous and the females lay one to four eggs in July. In terms of locomotion, B.
Then the anchored portion moves forward and the body anchors at a different spot. At 45 months, most females are biporue or longer, and this length is considered the start of the adult stage in B.

Positive Due to the large number of insects and other small invertebrates that Bipes biporus feeds bipss, Mexican Mole Lizards undoubtedly play a role in controlling the populations of their prey. Despite this extensive new database, we were unable to find morphological support for the major rearrangement of the deep divergences in Squamata proposed by recent molecular studies.

Of the specimens collected in the extensive study done by Papenfussthe ratio of adults to hatchlings stayed relatively constant throughout the study.
This is because sand does not hold water well so little is available to plants.
