Usually cute and harmless go together. Hamsters are cute and not deadly. Alligators are not cute and very deadly.
But there’s got to an exception to this rule. What’s the cutest most adorable thing capable of ripping your freaking face off?
Poison dart frogs are pretty adorable, and also poisonous. Thus the name.
I think some of the more ill-tempered of God’s creatures are pretty cute - wolverines, badgers, Tasmanian devils, etc.
A baby operating heavy machinery
Well, any of the large cats – tigers, lions, bobcats – have adorable kittens. Who, at a not very advanced age could totally rip your face off.
Same with baby grizzlies.
I agree with Zsofia. It might not rip your face off, but Phyllobates terribilis has some badass toxin. And I think they’re kinda cute.
Hippos are somewhat cute, and IIRC kill more people worldwide than any other critter or are at least certainly near the top of the list.
At 5’3" and looking for all the world like a friendly nordic peasant, I’d say Simo Hayha.
Giant pandas have attacked people in zoos.
I think polar bears are cute, and they’ll certainly rip your face off.
Dogs are cute, and they can kill a person. Wolves and coyotes are also cute, and also capable of attacking and killing humans.
For me, the Platypus!
Depending on your individual tastes, the Blue Ring Octopus. Cutest little buggers, very huggable, 5 inches long and packs one of the deadliest toxins on the planet, in quantities that would make you weep if you weren’t already dead.
They live in Australia, where else ?
It squeaks by on the “cute” parameter, but loses on “deadly”. The venom causes severe, crippling pain, but shouldn’t kill an adult.
A Bichon Frise made of anti-matter.
Chimpanzees are pretty cute, until one bites your eyelids, nose, lips, hands, and genitals off.
My ex-wife fits the bill.
How about Giardia? Those big, beautiful eyes, that winning smile… They won’t rip your face off, but they’ll sure give you the runs, which can, in some instances, be fatal.
Fugu fishare adorable and each mature fish carries enough toxin to kill 32 human adults.
Koalas are mean little bastards, but I don’t know that they’ve ever actually killed.
In a similar vein, the Irukandji jellyfish. If you are really unlucky you can get stung by one of these delicate, fragile 1-2cm living neurotoxin syringes 25m above the water.
