Northern Fulmar
The Northern fulmar is an abundant bird species found primarily in the North Atlantic and North Pacific oceans. They come in one of two types of color morphs: a light one and a dark one.
Similar to other kinds of birds, the Northern fulmar chick will projectile vomit as a way to deter its attacker. If a stream of bright orange puke that smells like rotten fish does not stop an enemy in its tracks, it is not clear what will.
When this caterpillar senses the presence of a predator, it changes the way it looks to resemble a snake by puffing itself up and using its patches to form false eyes. Few predators want to mess with a snake.
