Researchers at the University of Milano-Bicocca, Italy, found that cetaceans have even closer ties than imagined. They mourn the death of their relatives. Scientists have documented dolphins and whales staying with the bodies of dead members of their families for quite a while. "It's a sign of mourning. They feel pain and stress, they know something is wrong," says biologist Melissa Reggente.

The survey was conducted with seven species of aquatic mammals, including the killer whale, sperm whale and spinner dolphin. Mourning behavior was observed in all of them. With some animals, the signs became more pronounced when the dead was a calf.
