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.
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)
Enlarged middle row of scales under the tail (separates it from the southeastern five-lined skink)
Tail breaks off easily and twitches to distract predators; it grows back shorter
Where in Missouri
Nearly statewide, except for the extreme northern part of the state. MDC
