Curly-tails are alert and very fast.
The curly-tailed lizard, Leiocephalus carinatus, looks superficially like a heavy bodied swift (fence lizard) with an unruly, upcurled, tail. Present in Florida since the mid-1930s when it was deliberately introduced in the hope that it would consume unwanted insects in the sugarcane crops, this active diurnal Bahamian native is now seldom seen in the cane growing regions but has become common to abundant along the east coast of Florida from Martin to Miami-Dade counties and in lesser numbers in Monroe County. There it may be seen displaying on curbstones, parking barriers, and garden ornaments in locales as varied as sea-dunes to inland parks and urban neighborhoods.

The genus Leiocephalus is large and diverse. Alone, the species L. carinatus¸ the taxon present in Florida, contains 13 Bahamian and Cuban subspecies. Most are of quite similar appearance and the subspecies are best differentiated by range. Although over the years at least 3 subspecies (L. c. armouri, L. c. coryi, and L. c. virescens) have been introduced to Florida, only the first of the 3, the northern curly-tailed lizard, has become firmly established.

Although not particularly inclined to do so, this lizard would much prefer to bask or dart actively about at ground level as it forages for insects in piles of building rubble or oolitic limestone.
