Two endangered Mexican beaded lizards have hatched at Wroclaw Zoo in Poland, boosting the population of the venomous lizards.

The zoo said the lizards, which are difficult to breed in captivity, hatched in late February at its terrarium, where the eggs had been kept in an incubator since an adult female laid them in August.
