A scientist at the University of Zurich observed that, when faced with aggressive males, female moorland hawker dragonflies freeze mid-air, fall to the ground, and lie there motionless. In the research, more than 60 percent of the females observed escaped after faking their deaths.

It's a practice called sexual death feigning, which is an attempt to avoid injury and sometimes even death that can result from female dragonflies being coerced into mating. In addition to the dragonfly, four other species, like the spider and praying mantis, are known to practice sexual death feigning.

Found only in Southeast Asia, the slow loris is a small, monkey-like creature that you might recognize for its big round eyes.

They also have the distinction of being the only primate in the animal kingdom with a venomous bite. They lick a toxin-producing gland under their arm before deterring predators with their teeth. In humans, this venom provokes an allergic reaction that usually results in a painful swelling, though there is at least one report of a human dying of anaphylaxis from a slow loris bite.
