One of only two Omanosaura species, Jayakar’s Oman lizard (Omanosaura jayakari) is a large, slender lizard which is endemic to the Hajar Mountains of Oman and the United Arab Emirates.
Jayakar’s Oman lizard is variable in colour and patterning, but is usually brownish to greyish-green or bluish-grey above , often with pale blue or grey spots and irregular light and dark markings . The belly is usually white or creamy-white. In the male Jayakar’s Oman lizard there may be pale grey-blue, criss-cross patterning on the throat, and the male also has a longer and more robust head than the female .
Like other lizards in the Lacertidae family, Jayakar’s Oman lizard has a somewhat flattened body with long limbs, long toes and a very long tail , which in this species is twice the length of the head and body . The body of Lacertidae species is covered in small, granular scales, with larger and more conspicuous scales on the top of the head .
Jayakar’s Oman lizard can be distinguished from the closely related blue-tailed Oman lizard (Omanosaura cyanura) by its larger size and by the absence of a bright blue tail.
