Grey Slender Loris

Recently, the states of Kerala and Tamil Nadu have initiated efforts to restore habitats and strengthen monitoring mechanisms for the conservation of the grey slender loris, a rare and threatened primate species found in southern India.

About Grey Slender Loris

The grey slender loris (Loris lydekkerianus) is a species of primate belonging to the family Loridae. It is classified as a prosimian, which means it belongs to one of the oldest and most primitive groups of primates.

Habitat

The grey slender loris inhabits a wide range of forest ecosystems, including:

• Tropical primary and secondary rainforests,

• Dry semi-deciduous forests,

• Scrub forests,

• Swamps,

• Acacia and bamboo forests,

• Forest edges, and

• Montane cloud forests.

Geographical Distribution

The species is mainly found in southern India, particularly in the states of Karnataka, Kerala, and Tamil Nadu, and also occurs in Sri Lanka.

Physical and Behavioural Characteristics

The grey slender loris is a nocturnal hunter, active primarily during the night. It has no tail, and its flexible spine and long limbs enable it to move swiftly and silently across the forest canopy.

The species possesses opposable thumbs, which allow it to cling motionless to branches for extended periods. It has large, forward-facing eyes that provide exceptional night vision, aiding in nocturnal foraging.

Communication

Grey slender lorises communicate through a combination of vocalisations and scent marking, which play an important role in territorial behaviour and social interaction.

Diet

The grey slender loris is almost entirely insectivorous. More than half of its diet consists of ants and termites, making it an important species for natural pest control within forest ecosystems.

Threats

The species faces several threats, including:

• Illegal pet trade,

• Hunting for body parts, and

• Roadside captures, often resulting from habitat fragmentation and increased human–wildlife interaction.

Conservation Status

• IUCN Red List: Near Threatened

• CITES: Appendix II

• Wildlife (Protection) Act, 1972: Schedule I

These listings provide the species with varying levels of international and national legal protection.

Significance of Conservation Efforts

Protecting the grey slender loris is crucial for maintaining forest biodiversity and ecological balance, as the species plays a key role in controlling insect populations and indicates forest health.
