Despite their name, night lizards are active during the day.

Like other night lizards, it bears live young rather than laying eggs.

Like all night lizards, it is viviparous, giving live birth to its young.

However, the very limited lifestyle of night lizards has contributed to a high life expectancy.

They took no note of him; they were still taking turns listing night lizards.

Physically, night lizards are characterized by relatively flat bodies and heads.

Xantusia is one of three genera of night lizards (family Xantusiidae).

Night lizards were originally thought to be nocturnal because of their secretive lifestyle, but they are in fact strictly diurnal animal.

Yellow-spotted tropical night lizards live in decaying logs in wet climates.

Uncommon in the exotic pet trade, yellow spotted night lizards are aggressive and can deliver a painful bite to anyone who may handle them.

Snakes, flap-footed lizards, night lizards, and some skinks have brilles.

Family Xantusiidae (night lizards)

Tropical night lizards, particularly the yellow-spotted variety, are sometimes called Central American bark lizards by pet dealers and owners.

Like all night lizards, the desert night lizard is viviparous, giving birth to live young and producing 1 to 3 young from August to December.

The island lizards are much larger than their cousins in the genus, the desert night lizards (Xantusia vigilis) of southern California.

Yellow-spotted tropical night lizards also include all-female parthenogenetic (asexually reproducing) populations, located towards the southern end of their range in Central America.

It differs from the other night lizards in possessing two frontonasal scales, one frontal scale, no parietal scale, and a fourth finger with four phalanges.

Night lizards (family name Xantusiidae) are a group of very small, viviparous (live-bearing) lizards, averaging from less than 4 cm to over 12 cm long.

Night lizards have evolution to live in very narrow environmental niches—"microhabitat specialization"—such as rock crevices or damp logs, and may spend their entire life under the same cover.

Nyctosauridae (meaning "night lizards" or "bat lizards") is a family of specialized soaring pterosaurs of the late Cretaceous Period of North America and, possibly, Europe.

Granite night lizards most often occurs on rocky slopes with large, exfoliating boulders and abundant crevices, but are occasionally found in coastal sage scrub and chaparral without boulders.

Contrary to the reproductive strategies of most small lizards, night lizards tend to have very low reproductive rates, with several species giving birth to only one or two offspring, after a gestation period of about three months.

The chief attraction is Joshua Tree National Monument, a 467,000-acre preserve that is home for the tall, ungainly and prickly Joshua tree, not to mention coyotes, yucca night lizards, tarantulas, rattlesnakes and kangaroo rats.

Family Xantusiidae (night lizards)

His lizard work currently focuses on Scincomorpha, following on a career-long interest in the unusual clade Xantusiidae.

Gekkonidae, Pygopodidae, Xantusiidae.

Femoral pores are present in all genera in the families Cordylidae, Crotaphytidae, Hoplocercidae, Iguanidae, Phrynosomatidae, and Xantusiidae.

Recent molecular analyses confirm the clade made up of Cordylidae and Gerrhosauridae (Cordyloidea) and place it in a larger clade including Xantusiidae (Cordylomorpha Vidal & Hedges, 2009).
