What is suborder Pinnipedia?
Pinnipedia is a suborder of carnivorous mammals found exclusively in aquatic habitats. The suborder includes three recognized extant families: Odobenidae (walrus), Otoriidae (sea lions and fur seals), and Phocidae (true seals).
Are seals related to bears skunks and badgers?
Caniformia is one of two suborders within the order Carnivora and consists of the “dog-like” carnivores, such as dogs, wolves, bears, weasels, and skunks. It also includes the aquatic pinnipeds (eared seals, earless seals, and walruses)….Caniformia.

Do bears and wolves have a common ancestor?
Similarly, wolves and bears are not related. Their common ancestor is also the miacid, which has been extinct for many millions of years. Dogs have only been a distinct species for 30,000 years, having diverged from wolves, not bears.
What did seals evolve from?
Seals evolved from carnivorous ancestors that walked on land with sturdy legs; only later did these evolve into the flippers that the family is known for. Now, a beautifully new fossil called Puijila illustrates just what such early steps in seal evolution looked like.
What suborder are seals in?
Together with walruses, seals and sea lions are classified as pinnipeds (suborder Pinnipedia).
What is the Pinnipedia family?
The pinnipeds are a group of 33 species of aquatic fin-footed mammals composing three families: the true seals (family Phocidae), the fur seals and sea lions (family Otariidae), and the walrus (family Odobenidae). Pinnipeds live only in rich marine environments and a few inland or tropical freshwater systems.
Is a raccoon a member of the weasel family?
For much of the 20th century, virtually all of the smaller dog-branch carnivorans that are not members of Procyonidae (the raccoon family) were lumped together in the large group Mustelidae, popularly termed the weasel family.
Did dogs evolve from seals?
“Dogs and seals are not in the same family, however, and are not closely related. The family that compromises seals, Pinnipedia, split from other caniforms around 50 million years ago.” Upon further inspection, there are some pretty obvious phenotypical distinctions between seals and dogs.
Who did wolves originate?
Wolf Origins. The Evolutionary history of the wolf is not totaly clear, but many biologists believe that the wolf developed from primitive carnivores known as miacids. Miacids ranged from gopher-sized to dog-sized animals, and appeared in the Lower Tertiary about fifty two million years ago.
What are bears ancestors?
The evolution of bears as we know them today, started around 30 million years ago. Their ancestors evolved into a family of small mammals known as the Miacids (Miacidae). The bears, small bears and also the canines developed from the Miacids.
Are seals and walruses related?
Scientific Classification: The order Pinnipedia includes seals , sea-lions and walruses. Seals and walruses share similar fin-like flippers but are classified into different ‘families’, with walruses falling into the Odobenidea family and seals falling into either the Phocidae or Otariidae family.
Do seals like humans?
