Dolphin,
«DOL fuhn», is the name of a group of
sea animals closely related to whales and porpoises.
Like whales and porpoises, dolphins are mammals,
not fish. Mammals, unlike fish, feed their young
with milk that is produced in the mother's body.
Also unlike fish, dolphins have lungs and are warmblooded—that is, their core body temperature always
stays about the same, regardless of the temperature
of their surroundings.
Many people believe that dolphins rank among the
most intelligent animals, along with chimpanzees
and dogs.
Dolphins, porpoises, and whales belong to a group
of mammals called cetaceans

Dolphins and porpoises closely resemble each other,
and people often confuse the two groups. Their chief
differences occur in the snout and teeth. Dolphins
have a beaklike snout and cone-shaped teeth.
Porpoises have a rounded snout and flat or spadeshaped teeth. Whales grow much larger than most
dolphins and porpoises.
