About Ptyas fusca (Günther, 1858)
Ptyas fusca, commonly called the white-bellied rat snake or brown rat snake, is a species of colubrid snake. It is distributed across Indonesia, Brunei, Malaysia, Thailand, and Singapore. This species favors forested habitats. Its known prey includes frogs, lizards, and fish. When disturbed, Ptyas fusca typically stays still and holds its neck erect, which acts as a threatening posture. Adult individuals have upper body coloration that ranges from brown to brick-red, and their ventral scales are white to pale yellowish. A defining characteristic of this snake is thick black stripes running along both sides of the posterior part of its body and its tail. Juveniles are most often greenish in color. The snake’s pupil is large and rounded.
