Not sure how rare they are, but I’ve seen wild crested caracaras a few times.

Desert tortoise, and an old one at that. Was bigger than a basketball.

I’m big into (responsible) nature tourism and I believe Mountain gorillas are the most rare. Black rhinos are also pretty critically endangered but there’s successful breeding programs at zoos for them so I would think they’re less threatened.

I went to the Galapagos once and some of the islands have some very rare species. But their habitat is protected and isolated so it’s not like endangered species that are threatened by habitat loss or war or whatever.

Not super rare, but a wolverine

Quokka on Rottnest Island (Western Australia)?

Followed by trying to stop fuckwits from playing “quokka soccer”. 🤭

Probably a California Condor at the San Diego Zoo.

Kemps Ripley sea turtles

In my area,

Pheasants and peacocks

Giant Millipede and Armoured Millipede. Not the rarest but you will never seen one without going into the forest.

Used to have a bush about 5 feet from my bedroom window that Cardinals would nest in.

Probably wild camels in central Australia or a platypus when I was young.

Saw a lynx cross the road ahead of us in the Yukon.

I saw a big white owl. It looks like as tall as a toddler. Then it flew away before I can even react.

African penguins maybe? They’re endangered. I took my partner to feed them at an aviary.

I feel like I’ve seen a black rhino before, maybe at the San Diego zoo as a kid or something. Those are critically endangered, all but one subspecies extinct.

Orcas, maybe?

I don’t even know what the rarest animal I would have seen in person is, considering many zoos and aquariums have endangered species in their care and I like going to them. I went to the Sacramento zoo over this last weekend, too.

In the wild, though? Could either be orcas or grizzly bears.
