What are three intersting facts about a lobster, killer whale, turtle, great white shark, and manta ray?

Hi! I need to have three interesting facts for each of these sea animals, lobster, killer whale, turtle, great white shark, and a manta ray. I've been trying to look on the internet but I can't seem to find any interesting facts. So if you could take the time to help me find some interesting facts about the animals than that would be GREAT! You don't have to find all of them, it's ok if you kelp me just do one animal :) thanks so much!!
