Fugitive animals were a large component of the city-planet Coruscant's "wild" fauna. Many exotic trophy species were smuggled in from other planets for the pleasure of Coruscanti citizens. Often, these creatures remained too wild or dangerous to be domesticated, and were either surreptitiously released into Coruscant's artificial environment or escaped on their own from animal traders. One such species were the narglatch, a species which made cute pets when young, though they invariably caused problems once they began to grow to maturity. Some of the more dangerous predatory animals even killed and ate their masters before escaping.
Though they were far from their homeworlds, many of these escaped species were able to eke out an existence on Coruscant. Some animals migrated to certain areas, like the wampas who adapted to Coruscant's cooler polar regions. The lower levels of Coruscant were infested by dangerous creatures like anoobas, saw-toothed granks, and veermoks, who feasted on garbage or on other creatures. Sometimes, these creatures made it too dangerous for the inhabitants of the lower levels to go out at night.
