Other forms: cockroaches
A cockroach is a large insect that's a familiar urban pest. If you've got cockroaches in your apartment, you'll see them scatter when you flip on the light in your kitchen at night.
Cockroaches have been around for hundreds of millions of years, and experts guess they might outlive humans. These hardy insects have adapted to so many threats over time that they're nearly indestructible today. For example, radiation that would kill you won't harm a cockroach. It's almost impossible to drown them (they can live for hours without oxygen), and they're immune to most of the poisons people use on them. Cockroach comes from the Spanish cucaracha, "beetle."
