Broad-headed Skink

Plestiodon laticeps

Not stated

Venom
No official source we use states whether this animal is venomous. That does not mean it is harmless: do not handle it.
Size
About 6.5 to 12.75 inches in total length. Oklahoma gives about 12 inches for large adults and SREL up to 13 inches. Males are larger than females.
How to recognize it
  • Large, wide head; breeding males have swollen orange-red jowls.
  • Smooth, glass-like scales, short legs and a stocky body.
  • Upper-lip scales separate it from five-lined skinks: Maryland, Tennessee and North Carolina count five labial scales between the nostril and the eye rather than four. Oklahoma and Missouri count differently, around 8 or 9 in the full lip row.
Where in Maryland
This species is fairly common. They are found on the Coastal Plain of the Eastern Shore and Southern Maryland … DNR
93 records by month.
What the sources say

Range: This species is fairly common. They are found on the Coastal Plain of the Eastern Shore and Southern Maryland. Also rarely found along the Potomac Valley in Montgomery and Frederick Counties.

Habitat: A forest species. Extremely arboreal. It is generally restricted to the drier areas of low hills and knolls within woodlands, including the dry sandy ridges typically found along the eastern side of lower Eastern Shore rivers. (DNR)
