Dolphin won't see you later, alligator

This comic recently became my most-liked post on Instagram, with almost 200,000 likes as I write this. It also prompted a lot of questions, comments and debate. "Why is the alligator in the ocean?" "What's with that green color ... alligators are grayish blackish." "That's a crocodile, not an alligator!" "Dolphins are evil ... they murder sharks!" Some people said they got a laugh out of it, but others said it made them very sad. For my part, I was tickled to see so many varied reactions!
