We do have Zebra, have you never heard of a Zoo? (I jest; you are of course correct).
As for cross-walk making more sense; Zebra crossing are so named because of the black and white stripes they comprise of, they require you to have seen one, yes, but, I'd argue that without context "cross-walk" is no more descriptive.
Collectively, we call our crossings (Toucan, Pelican, Zebra, Pegasus), "road crossings". They are so named due to their properties; Toucan because "two (types of user) can" cross there, Pelican (formerly pelicon) because it stands for PEdestrian LIght C[O]Ntrolled crossing), Zebra for its stripes, and Pegasus due to the buttons being accessible at heights suitable for those riding horses.
Another one that I've seen on reCraptchas is "Boardwalk". If it had not been for the song "Under the boardwalk" I'd have had no idea what that was referring to. We call it a "Pier" round these parts. Taking Crosswalk as a reference, Boardwalk sounds like it should therefore refer to a place where you walk on some boards... such as where there are roadworks... or a wooden bridge... or outside the saloon in a Western.
In fairness, I don't think this is well known in the US. My impression was always that a boardwalk is just a pier that no longer has any use for naval stuff, so they built a carnival on it.
Pier is a more familiar term to me. I think I've only heard the term boardwalk in relation to some place in New Jersey.
Hmmm... "Pier" doesn't really have any naval connotations in Uk English. Somewhere ships [naval or otherwise] tie up would be a "Jetty". A pier would usually suggest what you're describing as a 'boardwalk' -- found in a seaside town, with cafés, amusements and other entertainments on it and lots of people strolling about eating ice cream.
