Unlike most caterpillars, which eventually metamorphosize into a winged moth or butterfly, crawlers spend the entirety of their lives in a larval state. While slow, crawlers possess a slew of defensive mechanisms which protect them from hungry predators as well as help them subdue their own prey. These include several sharp black horns, a sticky silken thread emitted from a gland within their mouths, and an odorless, yet deadly poison secreted from their skin.
