Puffer fish are best known for their ability to puff up into spiny, poisonous balloons.
But, to be honest, we're even more impressed by their unparalleled cuteness, which a recent video puts on full display.
The one-minute clip shows a spotted, yellow puffer fish scoping out a diver's camera, giving the internet a closer look at its oversized eyes.
With these saucer-like eyes, each of which can move independently of the other, puffers can see really well.
Their eyesight, like their puff reflex and their poison, likely developed to compensate for the fact that these guys aren't the best swimmers.
We can't know how puffer fish feel about humans, but they seem to get friendly with divers pretty often.
One video from 2012 even shows one patiently letting a diver pull a fishing hook out of its mouth.
But don't get too excited about striking up a beautiful interspecies friendship. Almost all fish in the puffer family carry tetrodotoxin, a neurotoxin that National Geographic calls 1,200 times more poisonous than cyanide.
Just one fish can contain enough of this toxin to kill 30 adult humans, and there is no known antidote.
