Science Trek
Science Trek is a place where parents, kids, and educators can watch short, educational videos on a variety of science topics. Every Monday Science Trek releases a new video that introduces children to math, science, technology, engineering, and math (STEM) career potentials in a fun, informative way.(Music) Joan Cartan-Hansen, Host: How are dogs and cats ears different than humans?
Dog ears are controlled by up to 18 muscles, while human use only six.
All those muscles help dogs better find the location of a sound, hear it more clearly and from farther away.
A cat's hearing is even better than a dogs.
Cats can hear a wider range of sounds and have 30 ear muscles especially designed to help them figure out what different sounds are.
Birds don't have external ears, just openings.
Their heads are shaped to direct sound into their inner ears.
Snakes don't have ears like us at all.
They feel vibrations and that's how they detect sound.
Some fish also detect sound through vibrations but their ears are on the inside.
Bony fish detect vibrations through their earstones called otoliths, but both fish and mammals use their ears to help with balance.
So that's something we have in common.
