JWST finds nine category-defying objects. Have astronomers found their "platypus?"

In the animal kingdom, one of the most bizarre discoveries of all-time was the platypus. When reports of the platypus reached the western hemisphere, most leading naturalists at the time assumed it was a hoax, including the first European scientists to examine a specimen in 1799. It was an animal that laid eggs, yet it was a mammal. It had the bill of a duck, but the tail of a beaver.
