  • Poaching

The Miyako Grass Lizard or Long-Tailed Emerald Grass Lizard, a species from the Lacertidae family, can be found in the Indo-Malayan Realm and was first described by French zoologist Francois Marie Daudin in 1802. Its name is a tribute to Japanese herpetologist Masanao Toyama. It is also called Takydromus (Greek for ‘speed runner’) Toyamai.

This lizard type from Squamata (scaled reptiles) has a body mass of 3.86 g and a total length of 10 in. Adults are green while juveniles are brown. Its long tail is used for grabbing onto something especially while balancing between high grasses. It feeds on insects, termites, spiders, snails, and small mammals. It prefers to forage in sunny grassland or bushland and becomes inactive during winter season.

Rapid deforestation within its various native habitats makes it in danger of extinction. It becomes more vulnerable to attacks by predators and larger animals while poachers sell it to the black market at 600 USD for a pair.
