Hive rat

This giant (up to three meters, 300 kilograms), nearly skinless, rapacious rodent inhabited the lower reaches and sewers of Coruscant. Origin unknown.

Its powerful teeth and jaws could wreak havoc on water and utility lines.

Mutant rats travelled in packs and constructed nests with litters of 10 pups or more.

These "rats" happily fed on duracrete worms -- their only benefit to residents of Coruscant. They were otherwise feared and despised. Homeless and fugitive residents who wandered the lower levels of Coruscant often fell victim to roving packs of mutant rats or hungry dianogas.
