What in the World is a Dugong?

Summary

The video talks about how Dugongs or sea cows are in danger of extinction. Dugongs are marine animals that live in the Middle East. Sirenia is the order of the placental mammals. This order also includes manatees and rays. Dugongs eat large amounts of sea grass and that is getting polluted by humans, and that is why they are in trouble.

Relevance
It is related to our subject because this video mentions how these creatures came to be through evolution. It also talks about natural selection and how this species will become extinct if we don't do anything about it.

In many of the scenes, the Dugongs and sea turtles had other fish on them. How come those fist rely on the Dugongs and sea turtles for transportation if it appears that they can swim on their own?
