Learn how some animals use defensive vomiting to scare off predators, in this video from NOVA’s Gross Science series. European Roller chicks spew a smelly orange vomit when touched, deterring predators and alerting parents approaching their nest that a predator might be nearby. Fulmars—a type of seabird—can shoot a stream of yellow stomach oil to a distance of six feet. The oil can lead to the death of the predator by hindering it from flying or swimming. Camels are also famous for spitting saliva and regurgitated stomach contents. This resource is part of the NOVA: Gross Science Collection.
