Primates:

Toque Macaque (Macaca sinica): Endemic subspecies. Found near water, highly vocal — alarm calls are key to the acoustic ecosystem.

Tufted Grey Langur (Semnopithecus priam): Large, silver-grey monkeys. Deep guttural alarm calls indicate ground predators.

Small Carnivores:

Rusty-spotted Cat (Prionailurus rubiginosus): One of the world's smallest wild cats (1–1.6 kg). Extremely rare. Wilpattu is one of the few reliable locations.

Fishing Cat (Prionailurus viverrinus): Medium-sized wild cat specialised for wetland hunting. Occasionally seen at dawn near remote villus.

Indian Pangolin (Manis crassicaudata): Nocturnal, covered in keratin scales. Critically endangered due to poaching. Night walks near bungalows occasionally produce sightings.

Water Buffalo (Bubalus arnee): Wild buffalo, found near permanent water. Herds of 10–30. Maintain 50m distance.

Wild Boar (Sus scrofa cristatus): Common across all sectors. Often seen with juveniles in single-file family groups.

Indian Muntjac (Barking Deer) (Muntiacus vaginalis): Small deer, 50–60 cm at shoulder. Named for dog-like bark alarm. More often heard than seen.

Mouse Deer (Chevrotain) (Moschiola memmina): Tiny deer, 25–30 cm. Nocturnal, rarely seen. A lucky sighting.

Grizzled Giant Squirrel (Ratufa macroura): Largest squirrel (up to 1 kg). Striking colouration, seen leaping between canopy trees. One of four endemic squirrel species.
