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.
=True seals=
Sea lions are in the family Otariidae ("eared seals"), therefore they have external ears and hear stuff very much the same way we do. The family Phocidae ("earless seals") has no visible ears, but can still hear.
External ears
Yes although they are more adapted for underwater.
No. Harp seals are native to the North Atlantic and Arctic Oceans.
it is true harp seals live in saltwater.
if they are not a true seal the they do have ear
The Harp seal is a true seal. It has no ear flaps and uses its rear flippers for propulsion and its front flippers for steering. And most Artic seals are True seals.
Yes, it's true. They can hear noises from a mile away.
The Scientific Name of the 'Weddell Seal' is Leptonychotes weddellii and belongs to a group of seals known as Phocidae - or true seals.~ hope this helped :)
Otariidae (sea lions and fur seals), Phocidae (true seals), and Odonobenidae (walruses).
a fur seal is a type of seal. Fur seals are any of nine species of pinnipeds in the Otariidae family The true seals or earless seals are one of the three main groups of mammals within the seal suborder, Pinnipedia. All true seals are members of the family Phocidae. They are sometimes called crawling seals to distinguish them from the fur seals and sea lions of the family Otariidae. Seals live in the oceans of both hemispheres and are mostly confined to polar, sub-polar, and temperate climates, with the exception of the more tropical monk seals. - Wikipedia
