This sign, posted on a pier at Fort DeSoto Park, south of St. Petersburg, Florida, is not dolphin approved.
Dolphins are highly intelligent animals, fully capable of serving in their role as a top predator in the ocean. Yet like all intelligent creatures, they can also be lazy, and accepting food from humans diminishes their skills in hunting for their own food. Dolphins are also incredibly strong and fast, and harm or kill humans by accident simply due to the vast differences in strength, speed, and swimming ability.
Still: the dolphins definitely did not approve this sign.
