Plestiodon gilberti
Plestiodon gilberti, commonly known as Gilbert's skink, is a heavy-bodied, medium-sized lizard found in the southwestern United States and northwestern Mexico. Adults typically reach a total length of 7 to 12 cm and are uniformly colored in shades of green, grey, olive, or brown, while juveniles display distinct stripes. This species is known for its secretive nature, foraging within leaf litter and dense vegetation, and its unique feeding behavior of ingesting prey headfirst.

About Plestiodon gilberti
Gilbert's Skink
Plestiodon gilberti, commonly known as Gilbert's skink, is a species of heavy-bodied, medium-sized lizard belonging to the family Scincidae. This species is endemic to the southwestern United States and northwestern Mexico, with its primary range encompassing California and extending into parts of Arizona and Nevada, as well as northern Baja California.
Physical Characteristics and Habitat
Adult Gilbert's skinks typically grow to a total length of 7 to 12 cm (3 to 4.5 inches). They are characterized by their robust build and small legs. Adult coloration is generally uniform, appearing in shades of green, grey, olive, or brown. Juveniles, however, exhibit distinct striping on their sides and back, which fades as they mature, particularly in males. The species inhabits a diverse range of environments, from sea level up to approximately 2,200 meters (7,200 ft). They are most frequently found in open areas within grasslands, chaparral, or pine forests, actively avoiding dense vegetation and heavily forested locales. Gilbert's skinks are skilled burrowers, often creating their own shelters beneath rocks or decaying logs.
Behavior and Diet
Gilbert's skinks are generally secretive and are seldom observed in the open. Their foraging behavior involves searching through leaf litter and dense vegetation, and they are known to dig through loose soil. A notable dietary habit is their insistence on ingesting prey, such as insects and spiders, headfirst, which is believed to minimize struggle with potentially difficult prey.
Reproduction
The reproductive season for Plestiodon gilberti is influenced by geographical location and yearly environmental conditions. While specific timing is not precisely documented, it is thought to be similar to that of the Western Skink, with egg-laying occurring in June and July. Adult females create nest chambers in moist, loose soil, typically at a shallow depth. Each clutch usually contains between 3 to 9 eggs.

What kind of habitat does Gilbert's skink prefer?
Gilbert's skink inhabits a variety of environments from sea level to elevations of about 2,200 meters. It is most common in open areas within grasslands, open chaparral, or open pine forests, generally avoiding heavy brush and dense forests.
What does Plestiodon gilberti eat?
This species typically feeds on small invertebrates, such as insects and spiders. A distinctive feeding behavior is its insistence on ingesting prey headfirst, regardless of the prey's orientation.
How do Gilbert's skinks reproduce?
The reproductive season varies geographically and with local conditions. Females construct nest chambers in loose, moist soil, typically laying between 3 to 9 eggs. The timing of reproduction is likely similar to the Western Skink, which lays eggs in June and July.
What are the physical characteristics of Gilbert's skink?
Gilbert's skink is a heavy-bodied lizard with small legs. Adults are uniformly colored in green, grey, olive, or brown. Juveniles have light stripes on their sides and back, enclosing a broad black or brown stripe that stops near the tail base; these stripes fade with age.
Is Plestiodon gilberti territorial?
Unlike some other Plestiodon species, male Gilbert's skinks are not observed to be territorial. When confronted or threatened, they typically flee into leaf litter or dense vegetation to escape sight.

Anolis auratus
The grass anole, Anolis auratus, is a lizard species found across Central and South America, known for its tan coloration with distinctive stripes and spots. Unlike many of its relatives, it inhabits open grasslands rather than forests, adapting to transient environments and engaging in a unique "tyrant-subordinate" social system among males. This species is an opportunistic insectivore, relying on a sit-and-wait hunting strategy.
Diplodactylus intermedius
The Diplodactylus intermedius, commonly known as the eastern or southern spiny-tailed gecko, is a medium-sized lizard endemic to semi-arid regions of Australia. It is characterized by distinctive orange-brown spines along its back and tail, which can exude a foul-smelling fluid as a defense mechanism. This nocturnal and terrestrial gecko inhabits mallee shrubland, woodland, and grassland environments.
Lialis burtonis
Burton's legless lizard (Lialis burtonis) is a unique reptile native to Australia and Papua New Guinea, characterized by its complete lack of forelimbs and greatly reduced hind limbs, resembling a snake but distinct in its evolutionary lineage. This species is a visual predator with specialized adaptations for capturing and consuming other lizards, often found in diverse habitats from deserts to rainforest margins.
