And if comes under sustained attack it responds by sending its compatriots into a super-breeding frenzy in which millions of replacements are created.

Slow loris:

Glands on the inside of their elbows secrete a toxin that smells like sweaty socks. They cover their babies in the toxin to protect them from predators, and put it in their mouths to give themselves a venomous bite, delivering the toxin via their lower incisors.

Evil humans:

The small, nocturnal creatures are often trapped in the wild and have all of their teeth pulled in order to be sold as tame or as babies, according to CITES' report.
