Reproduction

Mating for the armadillo lizard occurs during early spring with the young being born six to seven months later.

Unusually for a lizard the armadillo girdled lizard will give birth to between one and two live juveniles. One is most common. These are quite large compared to other juvenile lizards.

They will provide some level of maternal care to their young and these young often remain in their parents family group for a period of time.

Behavior

Armadillo girdled lizards form family groups which typically include 3 or 4 members but have been recorded with as many as 50. These are made up of both genders. Smaller groups tend to only include a single male but larger groups may have many.

These lizards will spend part of their day basking in the sun. They are diurnal spending the day searching for food.

They will seek shelter in a burrow, rock crevice or among tree roots. Armadillo lizards are considered shy and dive for cover if disturbed.

Armadillo girdled lizards will communicate through head bobbing, tail wagging or tongue flicking.

Predators and Threats

Natural predators of the armadillo girdled lizard include birds of prey.

When threatened the armadillo girdled lizard will curl up in to a ball and hold its tail in its mouth. This will present the spines outward to help protect them against attack. When threatened they may hold this position for up to an hour.

Where they are close to cover they will wedge themselves between rocks rather than roll up. Their flattened body means they can enter spaces smaller than most of their predators.

Armadillo girdled lizards are able to perform tail autonomy. This allows them to lose their tail and grow it back to escape a threat.

Humans have affected the population of the armadillo girdled lizard though over collection to fuel the pet trade. Their habit of living in groups makes it easy for poachers to collect large numbers and this could wipe our entire populations.

Quick facts

The name of the armadillo lizard comes from the South American mammals famous for rolling up in to a ball when threatened.

Their scientific name Ouroborus cataphractus comes from the mythical Ouroboros which is found in many ancient cultures. This Ouroboros is said to eat its on tail to sustain life in an eternal cycle of renewal.
