Animal Sounds and Communication

October 15, 2000

Scientists know how difficult a task it would be for a Dr. Doolittle to truly talk with the animals, for each animal has its unique and often sophisticated method of communication. Crocodiles make special calls and bellows, bats and whales use sound to navigate and insects can communicate in such varied ways as touching antennae, emitting chemicals or producing supersonic sounds that are beyond a person's hearing. Discover the many ways animals communicate as well as real-life research of people trying to talk with animals through these direct links on The Times Launch Point Web site: http://www.latimes.com/launchpoint.
