What?
Small invertebrates, most commonly termites, occasionally plants
How Often?
Adults eat three times a week
How?
They hunt through sit and wait tactics
Any Special Food?
No, nothing special
Armadillo Lizards live in groups of up to 60
Males protect the territory
Females take care of young
Male - led groups
Groups made up of individuals of all ages, both male and female.
Communicate through tail waving, head bobbing, and tongue flicking
Armadillo Lizards mate once a year
They are polygynandrous
Both genders have multiple mates in the mating season
They do not have mating rituals
They produce 1-2 offspring each time
Gestation lasts 6 - 8 months
Ovoviviparous
Eggs hatch inside mother
Reach sexual maturity at 3 - 4 years old
Armadillo Lizards stay in family groups for life
No difference in male and female development
Predation
Its primary predator is birds of prey
Most animals will not attack it because of its tough scales
No sexual competition deaths
No prominent diseases
Main cause of death is predation
Inter-species
They will sometimes compete with other species of reptiles for food
Not much competition is seen otherwise
Intra-species
Since they live in such large groups, and do not mate with only one partner, there is little to no competition between individuals.
Any competition seen is over food.
No known competition with invasive species
NT (Near Threatened)
No official population count, however, they have been trending upward, and are widespread.
Based on this we can assume that their population numbers in the thousands.
Main human impact is catching them for pets.
This hurt their population until it was banned
This is because capturing many individuals from a group left the rest of the group vulnerable
Global warming could be a threat to them, as it might affect their habitat.
Humans have been interacting with them since they were discovered in 1828, though much more frequently in recent decades
The biggest effort made to reduce our impact on the species was the ban on the trade of armadillo lizards.
