True or false: Male northern coal skinks have a bluish head.

The statement that male northern coal skinks have a bluish head is false. In fact, male northern coal skinks typically exhibit a more muted coloration without the prominent bluish hue commonly associated with some other skink species or even some male lizards during breeding season. Their coloration typically consists of a more subdued pattern with shades of brown or gray, which helps them blend into their natural habitat. Young individuals or females may have different coloration characteristics, but the specific identification of males having a bluish head is misleading. Understanding the accurate coloration and physical characteristics of reptiles like the northern coal skink is crucial for proper identification and appreciating their adaptations in the wild.
