How do whales and dolphins communicate in water class 8?

Dolphins also, however, utilize high frequencies well beyond what human ears can normally register (150 kilohertz). How does the speaker work?

How do whales and dolphins communicate?

Toothed whales communicate using high-frequency clicks and whistles. Single click sounds are used mainly for echolocation while multiple clicks are used to communicate with other whales and even dolphins in the area. Baleen whales use low-frequency sounds, and these can be heard over long distances.

Can you hear a whale underwater?

Whales sing between 10Hz and 31 kHz. The low frequency sounds may travel 1000 miles underwater (but are inaudible to the human ear). The audible range sounds can be heard up to several miles, depending on water conditions. Not only can you hear them, you can hear whale song from miles away.

Can whales hear?

How do whales and dolphins hear? Whales and dolphins do have ears but they don’t have external sticky out ears like ours to funnel sound as they need to be streamlined for life in the water. Their ear canals are not open to the outside. Instead, they generally hear sounds through special structures in their jawbones.
