BiologyArmadillos have not been extensively studied in the wild and therefore little is known about their natural ecology and behaviour. Giant armadillos are fairly solitary and nocturnal, spending the day in burrows (5). They also burrow to escape predators, being unable to completely roll into a protective ball (2). These mammals are not territorial and feed in one area for a couple of weeks before moving on (5). Females give birth to a single young each year and these are weaned around a month later (6). Giant armadillos use their large front claws to dig for prey and rip open termite mounds. The diet is mainly composed of termites, although ants, worms, spiders and other invertebrates are also eaten (5).
