It has always amused me that the tourists to the US that I’ve spoken to are often very excited to see raccoons, and disappointed if they don’t see them before they leave.
Some others I’ve noticed on the east coast of the US are blue jays and cardinals. Boy, do people get excited about those if they’ve never seen them before! Very pretty birds of course, just very easy to get used to and see as uninteresting as well.
What about crocodiles? Alligators are in most reasonably large retention ponds in Florida. Most places just relocate them once they reach a certain size. They’re pretty common. Knew a guy in high school who had a side hustle of removing them from people’s swimming pools. They’re pretty weird if you’re not from a place used to them.
If you want to see a croc, just go walking near the shallow water of the top half of the country’s coast. You won’t see the croc for long, and it will be the last thing you ever see, but it will be up close and very personal.
Seriously though, you don’t go to see salt water crocodiles in the wild or even go near any body of water on the northern coast. If you can see one with the naked eye in the wild, you’re already too close. They’re extremely fast, extremely aggressive, and the males get up to 6m / 20ft long and 1000kg / 2200lb. They are very much a zoo only thing.
