The Solenodon
You might think that this is just a glorified, oversized rat, but the solenodon is definitely more intriguing than that. Scientific researchers are fascinated by this species because it closely resembles a species that went extinct during the era of the dinosaurs. They’re more closely related to shrews and moles than rats, and they’re also the only mammal in the world that injects venom into their prey when they’re eating. So that cute and fuzzy appearance? Yeah, you’re better off not trying to pet this one or else you could get bitten and that venom can do horrible things to your biology.
