Clips from that famous 20th Century Fox smash hit, "Satisfied Saurians." It was part of "Lew Lahr's Dribble Puss Parade," it seems. A bit more history, from Wikipedia:

The park began in 1893 on St. Augustine Beach as a minor attraction at the end of a railway running through neighboring Anastasia Island. The alligators were added at first to get visitors to buy souvernirs and see the museum there. Soon, though, the reptiles themselves became the point of interest.

Growing in popularity, the park moved to its current location in the early 1920s. The park changed owners in the 1930s, and after a devastating fire, they started reconstruction and expansion of the facilities. In 1993, for their 100 year anniversary, the park became the first place in the world to display every species of crocodilian.

If nothing else today, you've learned the term crocodilian.
