are dolphins related to whales?

Answer 1

Yes, both are mammals who once lived on the land and returned to the sea. Their legs were readapted to become finds, but they retain a finger structure.

Any sea going mammal that isn't a Killer Whale, a Pilot Whale, a dolphin or a porpoise is considered to be a cetaceans.

Porpoises are considered to be small cetaceans, they have different spade-like teeth than dolphins.

Dolphins is the class of animal that holds dolphins, killer whales and pilot whales.

according to Wikipedia: http://en.wikipedia.org/wiki/Whales
"The term whale can refer to all cetaceans, to just the larger ones, or only to members of particular families within the order Cetacea. The last definition is the one followed here. Whales are those cetaceans which are neither dolphins (i.e. members of the families Delphinidae or Platanistoidea) nor porpoises. This can lead to some confusion because Orcas ("Killer Whales") and Pilot whales have "whale" in their name, but they are dolphins for the purpose of classification."

According to Wikipedia: http://en.wikipedia.org/wiki/Dolphin
"Dolphins are aquatic mammals that are closely related to whales and porpoises. There are almost forty species of dolphin in seventeen genera. They vary in size from 1.2 metres (4 ft) and 40 kilograms (88 lb) (Maui's Dolphin), up to 9.5 m (30 ft) and ten tonnes (the Orca or Killer Whale). They are found worldwide, mostly in the shallower seas of the continental shelves, and are carnivores, mostly eating fish and squid. The family Delphinidae is the largest in the Cetacea, and relatively recent: dolphins evolved about ten million years ago, during the Miocene. Dolphins are considered to be amongst the most intelligent of animals and their often friendly appearance and seemingly playful attitude have made them popular in human culture."

According to Wikipedia: http://en.wikipedia.org/wiki/Porpoise
"Porpoises are small cetaceans of the family Phocoenidae; they are related to whales and dolphins. They are distinct from dolphins, although the word "porpoise" has been used to refer to any small dolphin, especially by sailors and fishermen. The most obvious visible difference between the two groups is that porpoises have flattened, spade-shaped teeth distinct from the conical teeth of dolphins."

Answer 2

They're kind of like second cousins. Dolphins and whales both belong to the order Cetacea but are in different families, genus, species.

They have the same:

Kingdom - Animalia
Phylum - Chordata
Class - Mammalia
Order - Cetacea

Search more about taxonomy of living things if you need more info.

Answer 3

Dolphins are smaller jointly as others are vast and a few dolphins can not stay in chilly water like whales could desire to. additionally the dolphin has a fin or maybe if that's referred to as on its head jointly as the whale would not. The dolphin is smarter than a whale 0.0
