Sting-Rays. They’re such beauuuuutiffffullllll creaturrrrrres! Sheeeee’s gorrrrrrrrrgeous! Arrrrgghhh!!!
Annoyed snakes and crocs everywhere celebrate.
You don’t want one for a pet. I used to work for a zoo and we had someone try to give us one. Beautiful animal but…yeah.
I love me some big cats though, any kind, though I love tigers and snow leopards best. I also like hedgehogs, bats, woodchucks/groundhogs, squirrels, and chipmunks.
I like foxes. They mate in my backyard and their kits play in the yard. They act like a cross between cats and dogs. I’ve seen them jump up and do a 180 in the air. But mostly I see them prancing across the lawn as if they own it.
Big question: Why do English people dislike foxes?
I love most animals, but my favorite non-domesticated critters are tigers and merecats.
Honorable mentions are wolves, elephants & dolphins.
Raven.
I love Koalas, & have since I was a very little kid.
It tends to be the more rural English that dislike foxes, because they can’t be bothered to secure the livestock that Mr and Mrs Fox like to eat, and therefore they live in continual conflict. I think they are great, although saying that, I’ve not seen any for a long while. My personal fave critters are bears and big cats, especially polar bears and tigers. The obvious power these creatures have, combined with their cuddliness, fascinates me.

Holy crap, am I the only one to mention Penguins!? Have you SEEN them?
I suspect this thread is a thinly veiled furry recruitment device.
Wolves, cos I have two in my coat of arms. I can rationalize it to Hell and back, but in the end it’s a case of “I like it because it’s mine!”
Platypuses (is that the right plural?) 'cos they look like the baby Jesus had been taking animals apart and putting them together and he had pieces left 
Deer. I do my very best every fall to try to find one (or more, depending on tags & seasons).
I’m a big fan of the raptors (hawks, owls, eagles, etc). Anything that flies, is cool to me, and the birds-of-prey are the coolest IMO.
Since my favorite has long ago been mentioned (black panther), I’ll submit one of the coolest animals I know of: the dik-dik. Speaking of domestication, I would never want a tiny dog but I think that a tiny antelope would be the coolest pet ever.
I like rattlesnakes. If I had to pick a favorite species, it would be the eastern diamondback.
I think tigers are magnificent.
Coelacanths. The most awesome animal…ever.
edit: wait, except dinosaurs. Dinosaurs were probably more awesome than coelcanths. But dinosaurs are extinct, and coelacanths are not. (At least not yet. They are highly endangered.)
Actually, I’ve always had a liking for the idea that some taxidermist in England was trying to cash in on the reports of odd critters being found in the new continent. In a fit of creativity, he made up the most ridiculous animal he could imagine, and construct, much like that monkey/mermaid mummy that was recently debunked. And then went quietly mad when, either through luck, or the action of a mischievous diety, live specimens started coming into London.
We have the good fortune to have echidnas breeding on our property - 18 acres of natural bush outside Melbourne. And of the above animals, we also have wombats and sugar gliders breeding here in the wild.
Given the hundreds of spiders, I am glad to say that I am a recovered arachnophobe who overdid the cure - and even more than the wombats, kangaroos, echidnas, sugar gliders, possums, birds by the hundreds, and other cuddly critters, it is the spiders I now adore the most. I have many that I’ve named who I watch at the edge of their burrows or in their webs. The entire property is an arachnid reserve. Pity the birds don’t respect my rules about not hurting spiders!
I once had a conservatory for endangered cats. I would like to say that we had a snow leopard, as I like them in principle but never met one – our permits only went up to 50 pounds. Of the ones we actually had, I really enjoyed the tamarins best, even though they presented a poop problem. A flying poop problem, mostly.
Despite the flying poop I enjoyed them very much. As a companion I liked the bobcats and servals quite a lot. A serval is very like a dog in some ways, but they need a lot of entertainment or they go loopy. (That’s a technical term) Caracals are delightful but territorial as all hell and so present an issue for a smaller conservatory. At least ours was and did.
The one that touched my heart though was a female Asian Leopard Cat named Baba Yaga. She was a terrible companion animal, but she really had something. Some kind of integrity, something untouchably herself, despite all she had been through. (Most of our cats were temporary residents who stayed with us because they had been illegally imported and zoos didn’t want them for various reasons. We were more a foster home than a permanent home for most of our, er, guests. She was in worse shape than our usual and took quite some nursing).
You can buy a Hyacinth - they’re very expensive and require lots of room, but they are sold as pets.
Big cats of all sorts, whales and birds of prey.
