I happen to see a very interesting interview on TV about the claims on mermaids on Discovery Channel. It was aired Sunday midnight as I can't sleep probably due to eating too full in a party. I turned on the TV and was just in time to watch this interview by Dr. Paul Robertson, a marine biologist. At first I thought it's most likely a hoax like most of you would think so. Watch with an open mind and you will see what unfolds.

The video they were talking about "Mermaid: The Body Found" was on Animal Planet which I found here.

One thing for sure the US navy does have a sonar weapon of some sorts which explains the beaching of the whales. What's incredible is the so called "Mermaids" that actually exists.
