The Sinai Agama (Pseudotrapelus sinaitus) is an agamid lizard native to northern and eastern Africa and the Middle East. It grows to about 25 cm (10 in) long, with the tail accounting for up to two thirds of the total length. It is active during daytime and feeds on insects and other arthropods and plants. During the breeding season, males become a striking blue colour to attract females.Photo: Ester Inbar
