dolphins can hear very well. They have tiny holes either side of the head. The specialised anatomy of a dolphin ear helps it to localise sound underwater, so that they can work out exactly where the sound is coming from. Humans can't do this underwater.
Most sound reception probably occurs however, through the fatty tissue in the lower jaw
no they dont even have ears
A cetacea is a big marine animal with long ears and long snout,but strangely it has fur!
Sometimes. Very small mammals will have small ears to help conserve their body heat. The exceptions to this are rabbits and hares. Also marine mammals (large and small) have lost their external ears for much the same reason. The exception to this is sea-lions who still have external ears. Large terrestial mammals have large ears as they have little need to conserve body temperature. The elephant has very large ears which they flap for the purpose of radiating away excess body heat.
yes they do have ears.
An elephant typically has two ears. Their ears are large and shaped like a fan, which helps to regulate their body temperature by providing heat dissipation.
All mammals have ears.
Most mammals have ears.
They are in the dolphins eyes, mouth, nose, ears, and its fins.
A giraffe has two ears, just like most mammals. Their ears are relatively large and mobile, allowing them to pick up sounds from different directions. This helps them stay alert to potential dangers in their environment.
The difference between a seal and a dolphin is a seal mainly stays in the Arctic's while dolphins stay in warm salty oceans (habitat). But in the appearance a dolphin does not have ''whiskers'' like seals do....Hope this is helpful
True seals have ears, just not external ears. Their ears are simple holes on the sides of their heads, but they have the same general internal ear structures as any other mammal. Sound carries very well in water, so true seals can hear perfectly well when submerged. Note that other marine mammals - whales, dolphins, manatees and such - also lack external ears. In air, they can still hear, but perhaps not as well as some other mammals.
Dolphins hear with their ears BUT when it comes to their sonar they 'hear' with their jaw.
