However, some of them are much more weird than they are wonderful; introducing, this thing...
The bizarre-looking creature was spotted by a man in Bali, Indonesia, last month.
Hari Toae, noticed the unusual animal scuttling his ceiling and wobbling around it's weird furry tentacles.
He said the home intruder 'looked like an alien' and he reckoned it had infiltrated his place to get shelter from the rain.
Speaking at the time, he said: "I will let it stay in my house, but only for the night. I don't want it to scare my guests away.
"It's not something I've ever seen before. I don't think it comes from this neighbourhood.''
While the animal is hardly a puppy or a bunny, the safe money says it probably isn't an actual alien.
It seems more likely that it belongs to a family of moths called Arctiinae. More specifically, it looks a bit like a creatonotos gangis, which you'll be pleased to hear is native to south-east Asia and Australia.
The species has wings and four tentacles, known as scent organs, which are used to produce pheromones to attract mates. While there is no arguing with the fundamental necessity of evolution, I think I speak for all of us when I say I'm not a fan of the wings and tentacles combo.

However, we do not know for definite what this creature was. Indeed, it could very well be a whole new species unknown to man.
The cat-fox cross looks like a slightly larger domestic cat but has now been given scientific recognition as its own distinct species.
There are reportedly just 16 of the cats on the island, so now wildlife experts are attempting to make them a protected species.
The cats are around 90cm (35inches) from head to tail and outwardly resemble a regular moggy - but they have wider ears, short whiskers and 'highly developed canine teeth'.
The cats, which are known on the island as Ghjattu volpe, have striped front legs and tails, dark back legs and a reddish stomach. They also have dense fur, which acts as a natural deterrent to fleas and ticks.
Chief environmental technician of the National Hunting and Wildlife Office Pierre Bendetti said: "We believe that it's a wild natural species which was known but not scientifically identified because it's an extremely inconspicuous animal with nocturnal habits."
It's certainly a lot cuter than the moth anyway.
