Knowra Dibamidae Dibamidae Dibamidae is a family of small, limbless lizards native to Southeast Asia and parts of the southwestern Pacific. Its members have reduced eyes and live mainly underground or beneath leaf litter.
Squamata : The reptile order comprising lizards, snakes, and amphisbaenians. Dibamidae is a distinctive family within this diverse reptile order.
Fossoriality : An adaptation for living and moving underground. Dibamids spend much of their lives in soil, where their body shape aids movement.
Squamate phylogeny : The evolutionary relationships among lizards, snakes, and other squamates. Dibamids occupy an early-branching position in many reconstructions, though their exact affinities remain debated.
Dibamus : A genus of limbless lizards in the family Dibamidae, distributed from South and Southeast Asia into the Pacific region. This widespread genus contains most described dibamid species.
Lepidosauria : The reptile group containing tuatara and squamates, including lizards and snakes. This broader lineage places dibamids among living reptiles.
Eye reduction : The evolutionary reduction of eyes in organisms living with limited visual input. Dibamids have tiny eyes beneath the skin, matching their subterranean habits.
Cretaceous : The geologic period from about 145 to 66 million years ago. Molecular estimates place the origins of major living squamate lineages deep in this period.
Anelytropsis : A genus of limbless lizards represented by the Mexican species Anelytropsis papillosus. Its isolated American distribution contrasts with the predominantly Asian range of Dibamidae.
Amphisbaenia : A group of mostly burrowing, elongate squamates commonly called worm lizards. Amphisbaenians resemble dibamids in their burrowing forms but belong to a different squamate lineage.
Chemical senses : Sensory systems that detect chemical cues through smell or taste. Chemical cues can help underground lizards locate prey and interpret their surroundings.
