s. The blue-throated keeled lizard likes to climb. It is easily frightened and is not often kept in captivity due to its protected status. Only two or four eggs are laid, and it has been assumed that females can produce eggs both in early spring and early autumn. The males bite the females in the neck during mating and don't let go for quite some time, which is common for ''Algyroides'' lizards.
