The broad-headed skink, P. laticeps, is similar, and may be difficult to distinguish from P. fasciatus. The former species usually lacks the two enlarged postlabial scales characteristic of P. fasciatus. [7] [8] Adult male broad-headed skinks, with their large size and swollen red head, are readily distinguished from P. fasciatus. [9]
Together with the Great Plains skink it is the largest of the "Plestiodon skinks", growing from a total length of 15 cm (5.9 in) to nearly 33 cm (13 in). A male broad-headed skink, illustration from Holbrook's North American Herpetology, 1842. The broad-headed skink gets its name from the wide jaws, giving the head a triangular appearance.
Male Solomon Islands skinks tend to have a broader head and a more slender body shape than female skinks. [15] Males have a V-shaped pattern of scales just aft of the cloacal opening, which is not present in female skinks. [15] The scales of Solomon Islands skinks are a dark green but are often speckled with light brown or black. [4]
It is a four-lined skink whose light stripes extend onto the tail. The broad dark lateral stripe is 4–4.5 scales wide and there are no light lines on top of the head. The dorsolateral light stripe is on the edges of the 3rd and 4th scale rows, counting from midline of back. One postmental scale is present.
The conspicuous coloring of species of Plestiodon is a survival trait: it attracts a predator's attention to the tail of the animal, which will break off when grabbed. A skink thus often manages to escape and hide under some rock, log, or fallen leaves while the predator still contemplates the wildly thrashing severed tail.

The basic ranks are species and genus. When an organism is given a species name it is assigned to a genus, and the genus name is part of the species name. The species name is also called a binomial, that is, a two-term name. For example, the zoological name for the human species is Homo sapiens. This is usually italicized in print or underlined ...
Range and density of non-human primates. Primates is a diverse order of placental mammals which includes monkeys, lemurs, galagos, lorisids, tarsiers, and apes (including humans). Members of this order are called primates. The order currently comprises 505 extant species, which are grouped into 81 genera. The majority of primates live in South ...
