In other words, Central and South America. Late sexual maturity, small clutch size, and a biennial bi;orus interval makes the reproductive potential of this species much lower than in most lizards.
Bipes biporous Cope However, Mole Lizards cannot regenerate the lost tail for future encounters with predators. Each x pixel slice is 0. The climate is seasonably cool in these areas. There is a positive correlation between tail autotomy and body size.
This structure is likely most effective at intercepting air-borne sounds. Reptiles and Amphibians in Captivity: When constructing and extending the underground tunnels, B.
Due to the burrowing lifestyle of B. Mexican Mole Lizards do not exhibit sexual dimorphism, so sexual identity can only be determined by looking at the gonads. The abstract is as follows: Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends.
Accessed December 19, at https: Energetics of Concertina Locomotion in Bipes biporus Reptilia: Their range extends throughout the southern half of the Baja California peninsula, west of the Peninsula Ranges. Hollingsworth and Frost, Conservation Status Despite their low reproductive potential, Mexican Mole Lizards are considered a relatively stable species, with no immediate concern of endangerment or extinction.

Despite this extensive new database, we were unable biporu find morphological support for the major rearrangement of the deep divergences in Squamata proposed by recent molecular studies.
Due to the large number of insects and other small invertebrates that Bipes biporus feeds on, Mexican Mole Lizards undoubtedly play a role in controlling the populations of their prey.
Wever and Gans, Hollingsworth and Frost, ; Papenfuss, Bipes biporus is an oviparous species. Bipes biporus plays a role in the ecosystem as a predator on terrestrial or burrowing invertebrates.
Digimorph – Bipes biporus (Baja worm lizard)
The three species of Bipedidae have small, powerful forelimbs that are specialized for burrowing. They are considered generalist predators because they will seize anything of suitable size that they contact.
The systems usually emerge to the surface under rocks or logs. Females bipez sexual maturity at about 45 months of age. Nocturnal mammals, such as badgers and skunks, that often prey on burrowing animals may be unable to find and dig up B. Mexican Mole Lizards build intricate burrowing systems that run horizontally right below the surface of the soil.
As is true of many squamates, their teeth are attached to the sides of the jaws in a pleurodont manner.
Mexican mole lizard – Wikipedia
All other members of this group are completely legless. Breeding— Longevity and Inventory Current January 1, The species only breeds underground. You can help Wikipedia by expanding it. The Mexican mole lizard Bipes biporuscommonly known as the five-toed worm lizardor simply as Bipesis a species of amphisbaenian which is endemic to the Baja California Peninsula.
Since the larger specimens are usually older, it can be inferred bipss older specimens are more likely to be tailless than younger specimens. This is because sand does not hold water well so little is available to plants.
The Ear and Hearing in Bipes biporus. Because Bipes biporus is a burrowing species, data are difficult to collect regarding the depths that they are found, bioes the average and maximum depths in the soil that they inhabit is unknown. Wever and Gans, Other Communication Modes vibrations Perception Channels tactile acoustic vibrations Food Habits Bipes biporus can be described as an opportunistic carnivore.
Vegetation is typically sparse, though spectacular blooms may occur following rain.
Papenfuss, In terms of locomotion, B. Females lay from 1 to 4 eggs per clutch, with an average of 2 eggs per clutch.
It is an opportunist carnivore and eats antstermitesground-dwelling insectslarvae, earthwormsand small animals including lizards. Occasional Papers of the California Academy of Sciences Mexican Mole Lizards will target a variety of prey including ants, ant eggs and pupae, cockroaches, termites, beetle larvae and other insect larvae, and most other small invertebrates.
Kearney, ; Papenfuss, Primary Diet carnivore eats eggs insectivore eats non-insect arthropods vermivore Animal Foods eggs insects terrestrial non-insect arthropods terrestrial worms Predation Due biporua its burrowing lifestyle, B.
Iteroparous animals must, by definition, survive over multiple seasons or periodic condition changes. Many people believe them to be snakes, so if they are dug up during agricultural activities, they are often unnecessarily killed out of fear.
