1.4 Prairies of Amazonia
Rattlebacks are relatively large rodents. They are distinguished for their thick armour plates covering its body. The material the plates are made from keratin, a material made of finely compressed hairs. Rattleback armour is primarily used for protection against predators like Carakillers but they can also be used for mating. Two males would rattle their armour and who ever makes the loudest noise win the right to mate. On each side of its body, a Rattleback possesses several sharp spines. These spines are used to lock the Rattleback into the ground. It is nearly impossible to dislodge it.Rattlebacks are omnivorous creatures. They mainly feed on roots and tubers but they can also feed on Carakiller eggs if they got the opportunity. Even if a Carakiller did catch the Rattleback its armour would prevent any harm to it.
Rattleback armour is also fireproof. As fires are common on the prairies, Rattlebacks has evolved to cope with the conditions. Having fireproof armour is important as Rattlebacks cannot outrun the fires due to the sheer weight it has to carry.
A Rattleback was seen unintentionally scaring off a troop of Babookaris. He was actually trying to scare off another male who invaded his territory. The two Rattlebacks rattled their armour at each other and the owner of the territory emerged victorious.Later, a Rattleback found a large nest of Carakiller eggs. It attempted to roll one away to eat but was caught by a male Carakiller. The bird tried to kill the Rattleback but the rodent's thick armour plating did its job. As the Carakiller was distracted by a lightning bolt, the Rattleback escaped.
During a fire, a Rattleback crouched on the ground, waiting for the wall of fire to pass. The Rattleback's fireproof armour saved it from the fire and when the storm passed, the Rattleback wandered off.
- The Rattleback is the largest and heaviest of the two Rattleback species.
