Grey Slender Loris (Loris lydekkerianus) lives in tropical dry forests across South Asia, India, Sri Lanka. Its conservation status is Near Threatened.
Fascinating facts about the Grey Slender Loris
- A gray slender loris can stretch its body to just 18-26 centimetres, yet it claims a home range as large as 2.36 to 3.6 hectares, and a core area of 0.37 hectares where it sleeps. Males roam farther than females, with adult male ranges reaching up to 3.6 ha while females stay within 1.12 to 1.59 ha. This expansive territory, despite the loris's tiny size, shows how much space each individual needs to find enough insects and safe sleeping spots, underscoring the importance of preserving large, contiguous forest patches.
- Gray slender lorises weigh between 180 and 290 grams, with males averaging 24.1 cm in length and females 23.4 cm. Their tiny bodies are built for a specialized grip: a reduced second digit and adaptations in the first metatarsal let them cling to thin branches for hours. These physical tricks let them hunt insects on delicate twigs.
- Insectivory dominates the gray slender loris diet: more than half of what they eat are ants and termites, and they also swallow beetles, spiders, and occasional small vertebrates. When tackling toxic prey, they perform a ritual of sneezing, head-shaking, and even washing their hands with urine. This elaborate detox routine lets them exploit food sources many other animals avoid, keeping insect populations in check.
- Photographers chasing glowing eyes have become a new threat: locals use bright torches, scare tactics, and even cut trees to capture lorises for paid shoots, then release them far from their home range. It illustrates how modern tourism can unintentionally harm a species already pressured by habitat loss and illegal pet trade.
- During the day, up to seven gray slender lorises huddle together in a "sleeping ball" of tangled limbs, often centered around an adult female and her offspring. At dusk they wake, groom each other, and then split to forage alone.

About the Grey Slender Loris
In the moonlit forests of southern India, the grey slender loris emerges as a phantom, its large eyes glowing like lanterns as it navigates the tangled underbrush with an uncanny silence. With each delicate step, its long, spindly limbs unfold and refold, propelling it through the shadows with a slow, hypnotic grace that belies a keen intelligence and sharp, predatory intent. As it moves, the loris's soft, woolly fur blends seamlessly into the dappled darkness, rendering it all but invisible, a fleeting whisper of presence in the night.
