- Blue Whale (Balaenoptera musculus)
- Fin Whale (Balaenoptera physalus)
- Sei Whale (Balaenoptera borealis)
- Bryde’s Whale (Balaenoptera edeni)
- Omura’s Whale (Balaenoptera omurai)
- Humpback Whale (Megaptera novaeangliae)
- Gray Whale (Eschrichtius robustus)
What whales have baleen plates?
Right whales have the longest baleen. Bowhead whales are particularly known for their long baleen plates, which reach lengths of 4 m (13 ft.). Bowhead whales typically have 230 to 360 baleen plates on each side of the upper jaw. Gray whales have about 130 to 180 baleen plates on each side of the upper jaw.
How do you tell the age of a whale?
When a necropsy is performed, the age of the individual is estimated by counting growth layers in the teeth (article in French only), in the baleen or even in the ear wax of the carcass. Like the growth rings of a tree trunk, there are usually one or two new growth layers for each year.
Where is the 52 hertz whale?
Pacific Ocean
Can you hear whale song above water?
While you may not be familiar with the sounds made underwater by the humpback whales, the sounds you are able to hear are the ones created by surface behaviour. The sound this creates can be heard above and below the water.
Do whale make sounds?
The bone structure of the middle and inner ears is modified from that of terrestrial (land-based) mammals to accommodate hearing underwater. Humpback whales produce moans, grunts, blasts and shrieks. Whales also emit low frequency sound waves.
Why do humans hear better in air than underwater?
Research: Ironically, sound waves travel 4.3 times faster underwater than they do through air. This is because water is denser than air. Since sound waves travel so much faster underwater than in air, it is much harder for us to detect where they are coming from.
Can humans hear underwater?
Sound that’s generated underwater stays underwater; very little sound passes from water to air. When your head is out of the water and you listen to a sound made underwater, you don’t hear much. But if you put your head under the water, the sound becomes much louder.
Does a scream travel faster underwater?
Sound waves travel faster in denser substances because neighboring particles will more easily bump into one another. Take water, for example. There are about 800 times more particles in a bottle of water than there are in the same bottle filled with air. Thus sound waves travel much faster in water than they do in air.
Why do you hear differently underwater?
Sound waves actually travel five times faster in water than in air. Underwater those sound waves don’t vibrate the ossicles bones in your inner ear. They go straight to the skull bones, vibrating that heavy bone you can touch just behind your ear. Because of that, you can hear higher frequencies underwater.
