Broad-Headed Skink

Plestiodon laticeps

Non-venomous per MDC

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 Missouri
Southern two-thirds part of the state. MDC
What the sources say

Venom: “All of Missouri’s lizards are harmless to humans, although some will attempt to bite if handled, usually causing a mild pain similar to being pinched. Some Missourians call broad-headed skinks ‘scorpions,’ but they are not venomous.” (MDC)

Habitat: As with all Missouri lizards, the broad-headed skink is active during the daytime, mainly between April and October. (MDC)

74 records by month.
What the sources say

Venom: “All of Missouri’s lizards are harmless to humans, although some will attempt to bite if handled, usually causing a mild pain similar to being pinched. Lizard myths: "MYTH: The tail of a skink is ‘poisonous’ and can sting you." The bright blue is not an indication of the tail being poisonous or venomous” (MDC)

Habitat: These skinks live in open woods, along wooded bluffs and on rocky, south-facing hillsides. (MDC)
