Amaral's Brazilian gecko explained

Amaral's Brazilian gecko (Hemidactylus brasilianus) is a species of nocturnal geckos from the arid Jalapão Region, Minas Gerais/Bahia (Brazil).^[1] It is a bluish-gray, oviparous tree-dwelling species, feeding on herbivorous insects and other invertebrates. It has immovable, or fixed eyelids. Being nocturnal, it has vertically oriented pupils. They have a life span of about 6–13 years and are sexually mature at 6–9 months old. They are about 13 cm long and 2 cm wide. They cannot change their colour. When attacked by a bird, they run in circles, confusing the enemy. When attacked by a ground animal, they climb a high tree, run in tall grass, or try to hide under leaves, rocks, and other things they can find. They are one of the smartest geckos on the earth, and are not endangered.
