3How They Hunt Dolphins have very good eyesight, although they also use their hearing to navigate their way around the ocean water. Dolphins, like other toothed whales, use echolocation to find food. They will make short clicks and listen for the echoes, which reveals the location of the fis...
Echolocation is mainly found in toothed whales, such as dolphins and sperm whales, not their toothless cousins. Thetoothless-whale group-- which includes humpback whales, blue whales and many other species -- possess a unique feeding adaptation called abaleen. The baleen is a wide plate in the...
Songs aren’t the only form of sound whales use.Porpoisesand dolphins which are smaller whales use high-frequency pitches. Unfortunately, these sounds don’t travel as far so they more often communicate using clicks or whistles. Dolphins and sperm whales use echolocation to navigate dark or murky...
Bats, who hunt at night, use echolocation to find their prey, too. First, the whale has to produce a sound. Toothed whales don't have anything exactly like our vocal cords, although they have similar structures. It's thought that they produce their sounds in their nasal passages [source:...
How the whales manage to subdue such able prey has been a mystery. One hypothesis, proposed more than 20 years ago, speculated the whales used powerful ultrasound shrieks to knock their squid prey senseless before scooping them up. Like bats and dolphins, some whales use ultrasonic clicks to ...
