The Florida sand skink (Plestiodon reynoldsi) is a species of lizard in the family Scincidae, the skinks. It is endemic to Florida in the United States.
It was described as a new genus and new species by Leonhard Stejneger in 1910 and named in honor of a certain Mr. A.G. Reynolds of Gulfport, Florida, who had collected the holotype. [4]
A unique lizard adapted to an underground existence, the Florida sand skink measures 10 to 13 cm (4 to 5 in) in total length and is a gray to tan color. Its forelegs are tiny and bear only one toe each; its hindlegs are small and have two toes. The tail comprises about half of the animal's total length. The sand skink has a wedge-shaped head, a partially countersunk lower jaw, body grooves into which the forelegs can be folded, and small eyes which have transparent windows in the lower lids. These features enable the lizard to move through loose sand. [5]
The diet consists of surface-dwelling invertebrates, including termites, spiders, and the larvae of antlions and beetles.
Florida sand skinks are most active in spring, during their mating season. They reach sexual maturity after one to two years and remain reproductively active for two to three years. About 55 days after mating, the female lays about two eggs, which hatch in June or July. [5]
It only occurs in Central Florida—115 known sites were recorded in 1999. The species is difficult to detect and may be found elsewhere during more intensive searches. It is present on the Lake Wales Ridge, the Winter Haven Ridge in Polk County, and the Mount Dora Ridge.
The Florida sand skink lives in areas vegetated with sand pine – Florida rosemary scrub and the longleaf pine – American turkey oak association, including Florida scrub habitat. Food supply and moisture levels are important factors in the species' tolerance of habitat. Florida sand skinks are most frequently found in the ecotone between Florida rosemary scrub and palmetto-pine flatwoods where moisture is present beneath the surface litter and in the sand. [5]
It usually remains underground and burrows 5–10 cm (2.0–3.9 in) beneath the soil to find food. [5]
The Florida sand skink was classified as a threatened species by the United States Fish and Wildlife Service in 1987. As of 2016 it is classified as vulnerable by the IUCN due to ongoing habitat destruction for the purpose of building developments, citrus plantations, phosphate mining, and wildfires. [1]
Plestiodon egregius, the mole skink, is a species of small lizard endemic to the Southeastern United States.
The western skink is a species of small, smooth-scaled lizard with relatively small limbs. It measures about 100 to 210 mm in total length. It is one of seven species of lizards in Canada. They spend much of their day basking in the sun. Their diet ranges widely, including spiders and beetles. Western skinks will bite if grasped and will flee if they feel threatened. It is a common but secretive species whose range extends from southern British Columbia and throughout Washington, Oregon, Nevada, Utah, Idaho, and Wyoming and into western Montana and northern Arizona and Missouri. They can also live in some areas of Texas It is widespread in northern California but primarily restricted to the coast in central and southern California. Found in a variety of habitats, this lizard is most common in early successional stages or open areas of late successional stages. Heavy brush and densely forested areas are generally avoided. Western skinks are found from sea level to at least 2,130 m (7,000 ft). This diurnal reptile is active during the warm seasons.
Plestiodon anthracinus, the coal skink, is a species of lizard which is endemic to North America.
The broad-headed skink or broadhead skink is species of lizard, endemic to the southeastern United States. The broadhead skink occurs in sympatry with the five-lined skink and Southeastern five-lined skink in forest of the Southeastern United States. All three species are phenotypically similar throughout much of their development and were considered a single species prior to the mid-1930s.
Plestiodon gilberti, commonly known as Gilbert's skink, is a species of heavy-bodied medium-sized lizard in the family Scincidae. The species is endemic to the southwestern United States, and grows to about 7 to 12 cm in total length.
The Great Plains skink is a species of lizard endemic to North America.
The prairie skink is a species of skink endemic to the prairies east of the Rocky Mountains in North America. It is one of only seven species of lizards that occur in Canada.
The (American) five-lined skink is a species of lizard in the family Scincidae. The species is endemic to North America. It is one of the most common lizards in the eastern U.S. and one of the seven native species of lizards in Canada.
Ceratiola is a genus of flowering plants with a single species, Ceratiola ericoides, the sand heath, sandhill-rosemary or Florida-rosemary, is a species of shrub endemic to the Southeastern United States.
Plestiodon inexpectatus, the southeastern five-lined skink is a common skink in the southeastern United States.
The four-lined skink is a species of lizard, which is endemic to North America. It is a medium-sized member of the Plestiodon skinks.
Plestiodon callicephalus, commonly known as the mountain skink, is a species of lizard, a medium-sized member of the Plestiodon skinks, endemic to North America.
Plestiodon multivirgatus, commonly known as the many-lined skink, the northern many-lined skink, or the variable skink, is a medium-sized species of lizard, a member of the North American skink genus Plestiodon in the family Scincidae. The species is native to the western United States.
Rhineura floridana, known commonly as the Florida worm lizard, graveyard snake, or thunderworm, is a species of amphisbaenian in the family Rhineuridae. The species is the only extant member of the genus Rhineura, and is found primarily in Florida but has been recorded in Lanier County, Georgia. There are no subspecies that are recognized as being valid.
Florida sand pine scrub is an endangered subtropical forest ecoregion found throughout Florida in the United States. It is found on coastal and inland sand ridges and is characterized by an evergreen xeromorphic plant community dominated by shrubs and dwarf oaks. Because the low-nutrient sandy soils do not retain moisture, the ecosystem is effectively an arid one. Wildfires infrequently occur in the Florida scrub. Most of the annual rainfall falls in summer. It is endangered by residential, commercial and agricultural development, with the largest remaining block in and around the Ocala National Forest. Lake Wales Ridge National Wildlife Refuge also holds a high proportion of remaining scrub habitat, while the Archbold Biological Station near Lake Placid contains about 20 km2 (7.7 sq mi) of scrub habitat and sponsors biological research on it.
The Florida scrub lizard is a species of lizard in the family Phrynosomatidae. The species is endemic to Florida, the United States.
The Florida peninsula inland scrub is a shrubland community found on the Florida peninsula. The largest remaining blocks of inland scrub are in and around the Ocala National Forest and in the Lake Wales Ridge National Wildlife Refuge. The Archbold Biological Station near Lake Placid contains about 20 km2 (7.7 sq mi) of scrub habitat and sponsors biological research on it. The scrub occurs on a series of north-south running ridges composed of sand derived from ancient dune fields. The soil, a type of entisol, is derived from quartz and is low in organic matter, silt, and clay. Because the low-nutrient sandy soils do not retain moisture, the ecosystem is effectively an arid one.
Plestiodon lynxe, also known commonly as the oak forest skink, is a species of lizard in the family Scincidae. The species is endemic to Mexico. There are three recognized subspecies.
