Additional common names include: cat-eyed night snake, come sapo, culebra de pantano, culebra destenida, machete savane, mapana de agua, mapana tigre, and ranera.[5]
Adults are about 750 mm (30 in) long and very slender. The head is distinct from the neck, and the large eyes have vertically elliptic pupils. The back is yellowish or brown with a series of dark brown or blackish spots often confluent into an undulous or zigzag stripe.[2]
Venom
It has a pair of enlarged, grooved teeth at the rear of each upper jaw (maxilla),[2] and produces a mild venom.[citation needed]. The venom affects the snake's natural prey (mainly small frogs and small lizards). The snake tends not to bite humans when handled, but when it does, the venom has relatively mild effects in most individuals; some describe it as a slight irritating/itching sensation with slight swelling. The snake is not considered a risk to human health.
Habitat
The snake inhabits moist areas.[5] It tends to be found in forest (moist and dry forest) as well as in areas near forest edge, including well vegetated urbanized areas near the forest edge. It is often associated with riparian zones, as well as the margins of swamps and marshes.
Behavior
Leptodeira annulata is nocturnal. It hunts and feeds in trees and on the ground.[5]
