These are turtles and they are eaten by sea gulls. The turtles eat sea weed and they are born on the beach. Then they move into the ocean when they come out of the sand and they try to not get eaten by the sea gulls.
This man bought this lion as a cub, and when it got too big he let it go into the wild. 10 years later it was the alpha male in a nature reserve in Africa. When the guy went to see it, the lion walked up to him and gave him a big hug.
