On survival...

If you're on a remote island. Um. You can find snails and eat them off the rocks. You have to become efficient at nabing yourself a fish if you want to eat. I don't know if you can find clams on a tropical island in the south pacific. I wonder. Um. I know you can even eat insects to stay alive. The giant clam they have in the south pacific is the one they always put in the cartoons. Um. You just wait for a shark to come around and then JAB! You have to cook it though. Put it on a hot piece of metal to fry it up from the plane reckage or something. You can eat bugs and worms to keep you alive as well.
