Description
The Five-lined Skink is a smooth, slender lizard that can reach 81
cm snout-vent length. Colouration varies depending on the age.
Juveniles and young adult females are glossy black with five cream
stripes on the back and bright blue to grey tail. The belly is
creamy white. Males and older females gradually fade in colour to
a uniform bronze. Males in breeding condition have a bright orange
chin and jaw.
Confusing Species
No other lizards are found in Ontario. However, the Prairie Skink and Western Skink
are similar. Both of these species have only four cream or white stripes although they may have
a tan or light brown stripe down the centre of the back where the fifth stripe would be on a
Five-lined Skink.
Distribution
In Canada this species is found only in southern Ontario from the
southern edge of the Canadian Shield south to Point Pelee National
Park. It is widely distributed in the eastern US as far south as
Texas and Florida.
Habitat
Along the Lake Erie shoreline, skinks are found in open forests and
small meadows on stabilized sand dunes. Along the southern edge of the Canadian Shield they
are found in open forests on rock outcrops.
Reproduction
Breeding occurs in May and early June. In 4-8 weeks, females lay
2-15 eggs in a nest excavated under cover or within a rotting log.
Several females may nest together and they attend the eggs until
they hatch in late July or early August. The hatchlings are
approximately 3 cm in body length at this time.
Natural history
Five-lined Skinks eat a wide variety of invertebrates such as
insects, spiders and worms. They hunt in leaf litter and woody
debris, tracking prey with their keen sense of smell. On cool
sunny mornings they can be seen basking in the sun but most often
they are found hiding under cover. They will also climb trees to
hunt, bask or escape predators. If a Five-lined Skink is caught by
the tail, the tail will break off and begin to thrash about. The
moving tail should occupy the would-be predator while the lizard
escapes. Over time, it will grow a new tail.
Conservation Concerns
Because of their striking colours, Five-lined Skinks are prized as
pets. Over-collecting has reduced populations in some parts of
their range. Numbers are also reduced in parks where patrons
remove or burn woody debris -- important habitat for skinks. This
species was recently designated as Vulnerable in Canada by COSEWIC.
