Ceratophora tennentii

Common Name: Ceratophora tennentii
Scientific Name: Ceratophora tennentii

Habitat

Ceratophora tennentii, commonly known as Tennent’s horned lizard, is primarily found in the lush forests of Sri Lanka, specifically in the central highlands. This species thrives in montane forests, characterized by moist, temperate climates and diverse flora. It primarily inhabits elevations ranging from 1,200 to 2,000 meters, where the cool temperatures and abundant vegetation provide an ideal environment for their survival.

Physical Characteristics

This species exhibits remarkable physical features, including a distinctive elongated body that typically measures between 15-25 cm in length. Ceratophora tennentii displays a vibrant range of colors, including bright green and brown, which helps it blend seamlessly into its leafy surroundings. Notable features include its horn-like projections on the head, which not only serve as a mating display but also as a defense mechanism against predators.

Behavior

Ceratophora tennentii is primarily arboreal, often found basking on branches or leaf litter. It displays a fascinating behavior of mimicking leaf movement to evade detection by both predators and prey. This species is diurnal, being most active during the day when it hunts for food or engages in territorial displays. They are known for their slow movements, which further aids in camouflage.

Diet

The diet of Ceratophora tennentii consists mainly of insects, including ants and beetles, making it an insectivore. They utilize their excellent camouflage to ambush unsuspecting prey, showcasing a typical feeding behavior that maximizes their chances of successful hunting. Their diet reflects their arboreal habitat, where they can also supplement their intake with occasional plant material.

Reproduction

Ceratophora tennentii exhibits ovoviviparous reproduction, meaning females give birth to live young rather than laying eggs. Breeding usually occurs during the monsoon season, between May and July, when food is abundant. Female Tennent’s horned lizards typically give birth to 2-5 offspring, which are independent immediately after birth, showcasing a unique reproductive strategy that enhances juvenile survival in the jungle.

Conservation Status

The current conservation status of Ceratophora tennentii is classified as vulnerable according to the IUCN Red List. Habitat loss due to deforestation and agricultural expansion poses significant threats to this species, resulting in a declining population. Conservation efforts are essential to protect their natural habitats and ensure their long-term survival.

Interesting Facts

One fascinating aspect of Ceratophora tennentii is its exceptional ability to change color in response to environmental changes, which aids in both camouflage and thermoregulation. This chameleon-like trait makes it an exemplar of adaptation in arboreal lizards.

Role in Ecosystem

Ceratophora tennentii plays a vital role in its ecosystem as both a predator and prey. By controlling insect populations, it contributes to the ecological balance within its forest habitat. Additionally, as a food source for larger predators, it is an integral part of the food web, showcasing its importance in maintaining biodiversity in Sri Lanka’s highland ecosystems.
