The dolphins use numerous tactics to capture their prey, and the most common one is hunting in groups. Sensitive beaked whales are well-adapted to be deep divers Whales and dolphins that have teeth and hunt other animals (as opposed to baleen whales, which scoop up plankton or schools of small fish) tend to stick to the upper 1500 feet of the water column, as do predatory fish like tiger sharks and bluefin tuna.

However, dolphins breathe fresh air from their lungs. A few dolphin species have small dorsal fins. To eavesdrop on the whales, engineers at the Naval Underwater Warfare Center in Newport, R.I., developed a program called M3R (Marine Mammal Monitoring on Navy Ranges), which allows the hydrophones to pick up the sound frequency of the "clicks" that beaked whales use to echolocate. “I happened to be in San Diego then, too, at a conference sponsored by the Southwest Fisheries Center in La Jolla. "A group of five or six came right close by the ship, no more than forty or fifty feet away. -.Whales are social creatures and live in groups; but they are not as friendly to humans as dolphins are. These whales use the fringed structure of their teeth to filter large amounts of water and trap plankton and small creatures.The other category for whales is toothed, which includes dolphins and sperm whales, amongst others.
