I found this short annoying. The narrator makes lots of really bad banter, and he's not half as clever as he imagines himself.
For one thing, dolphins and porpoises are separate species, but he uses the words interchangeably.
Second, it wasn't clear to me what this was. Was it "Marineland"? Was it "Marine Studio"? Was it "Marine Circus"? Was it a movie set? Was it scientific research? Was it a vacation spot? These are competing goals that don't work well together.
For some reason, they included lots of footage of a man underwater, feeding the fish and dolphins/porpoises, but repeatedly kicking and hitting a turtle who is also attracted by the food.
There is footage of loading a shark onto a boat, underwater shots of a ray, a manatee, an eel, and a variety of fish.
