Imagine living in the sea where it is permanently dark, cold, and food is hard to find. For many animals at depth, it may be weeks to months between meals. If you find something to eat, you have to hang on to it. This is why so many deep-sea fishes have lots of big teeth. This dragonfish, spotted off the coast of Australia, even has teeth on its tongue. They would be terrifying animals ... if they weren’t the size of a banana. (Photo by Julian Finn/Museum Victoria)

Volunteer rescuers prepare to drag a beached humpback calf to sea at Surfers Paradise Beach on August 8, 2011 on the Gold Coast, Australia. The humpback calf was stranded on the beach yesterday for hours before volunteer rescuers were able to drag it back to the sea. SeaWorld Australia says a mother and calf humpback were sighted near where the calf was released and are hoping to get photos to verify it is the same calf and that it has been reunited with it's mother.
