Shark Hearing | SHARK ACADEMY

August 21, 2019


How do sharks hear? And what frequencies are
most important? I’m Jonathan Bird and this is shark academy! You’d never know it by looking at them but
sharks have ears. Not that kind of ear! Shark ears are internal—only a tiny little hole
is visible externally, and if you didn’t know it was there, you would probably never
even see it. Sharks respond only to low frequencies between
about 10 and 800 Hertz. People can only hear down to about 20 Hertz, so sharks can hear
frequencies that are lower than people can hear. Extremely low sounds are more like vibrations
than sounds and these are detected by a system called the Lateral Line System, which is shared
by sharks and many fish. The Lateral Line System consists of tiny little
pores all over the shark’s body, and inside each pore is a cell that has basically little
hairs on it. When water moves over the pores, it moves the little hairs and it helps the
shark detect the vibration. When all the pores work together, they are like a little array
of vibration detectors. The Lateral Line is extremely important for sharks hunting in
low light because it can detect vibrations at close range without having to see what’s
going on. Well, now you know everything there is to
know about shark hearing and their lateral line system. And if you want to know some
more cool stuff about sharks, like how they smell, or how they see, or how they’re camouflaged,
check out our other great Shark Academy episodes. And if you haven’t subscribed, hit the subscribe

    Hello!

    As always I would say a great video. An educationnal vid about sharks is one way to understand how they react.

    Bye!

    Great video Jonathan!  I love the Academy videos because they teach us so much in a short period of time.  Do any schools have a collection of these video's to teach their students about sharks?  I would think with all the shark sightings in New England this summer it might be a great way to educate the kids.

    @BlueWorldTV I heard one time about a umm….. bull shark being in Canada lake Ontario!!!! But it was a long time ago:-D

    This segment was both quick and effective . . . kind of like a shark attack.  A good post and thanks for it!

    The visual frequency comparison was especially compelling.  That sort of graphic conveys your point easily, without taxing our sometimes woefully short attention span(s).

    A similar comparison, based on Cetacean frequency sensitivity, would also be well appreciated at my end.  No pressure, of course.

    You should do a vid on Dogfish sharks. Ok they're small and used for dissection, but still pretty cool.

    Okay, so they use it to find fish in the dark… But I wonder if any sharks use their hearing as a defense mechanism. I do not think they do, considering that Killer Whales use high frequencies to communicate and hunt, but it would be a good tool to avoid the shark eating cetaceans.

    thanks for this, now I know they can hear low frequencies lower than us

    I've loved sharks all my life and I'm very passionate about learning how to dive in hope to dive with sharks one day. The only problem is that my family haven't got the money for me to go out and learn and buy all the gear, does anyone have any suggestions on what I could do?

  • Reply 9mmor38 May 12, 2015 at 4:20 pm

    Should this be hearing or touch? Are they "hearing" or feeling vibrational changes due to the tiny ciliary bodies found in cells along the surface.

  • Reply TheWarrior831 October 29, 2015 at 2:11 pm

    do these pores detect both frequency and electrical currents? or is there a different set for each system?
