are dolphins mammals?
Answer 1: Whales, dolphins, porpoises, seals, walruses, and many other marine animals are mammals, not fish. The marine mammals exist because about 50 to 60 millions of years ago, some mammals wandered off of the land and into the ocean, and there they evolved into different types of marine mammals. With the exception of the five species of monotreme (egg-laying mammals), all modern mammals give birth to live young. Most mammals, including the six most species-rich orders, belong to the placental group. The largest orders are the rodents, bats and Soricomorpha (shrews and allies). Answer Wiki. Even though they live in the ocean all of the time, dolphins are mammals, not fish. Like every mammal, dolphins are warm blooded. Unlike fish, who breathe through gills, dolphins breathe air using lungs.Dolphins must make frequent trips to the surface of the water to catch a breath. The eyes are on the sides of the head near. the corners of the mouth. The ears are small inconspicuous openings located just. behind the eyes and have no external flaps. A dolphin’s pectoral flippers have all the skeletal elements of the forelegs of. terrestrial mammals, but are shortened and modified. Dolphins use their pectoral. flippers mainly to steer and with the help of flukes, to stop. Each lobe of the tail is. called a fluke. One of the most different characteristics amongst marine mammals like dolphins and whales is the fact that their breathing passage and food passage are completely separate. Unlike humans and most land animals dolphins do not breathe through their mouth, they breathe through their blowhole. Dolphins are modified mammals, they have adapted themselves to aquatic life. They are included in class Mammalia considering following features they possess: 1. Mammary glands (in females) that produce mammalian milk to feed their young ones. Yes dolphins are mammals or rather marine mammals. In fact because dolphins are mammals they are warm-blooded, child baring, milk producing animals that require air for survival. Dolphins have very good vision, both above and. below water. Bottlenose dolphins are usually grey to grey-black on the dorsal. (upper) surface fading to white on the belly and lower jaw. The belly may also be. pinkish. The rostrum (‘nose’) is usually well defined with a lateral or side crease. Like mammals, whales and dolphins breathe air through a pair of lungs, they are warm-blooded, their young drink milk, and they have hair (although very little). The whale is actually the closest living relative of the hippopotamus. Here's some good information on the difference between whales and dolphins and fish: For the 2010 documentary film, see Mammalian (film). Mammals are any vertebrates within the class Mammalia (/məˈmeɪli.ə/ from Latin mamma breast), a clade of endothermic amniotes distinguished from reptiles (including birds) by the possession of a neocortex (a region of the brain), hair, three middle ear bones and mammary glands.
Yes, whales, dolphins, porpoises, seals, walruses, and many other marine animals are mammals, not fish.
