How many animals have a blowhole?
Whales, dolphins and porpoises have a blowhole, (or nostrils), on top of their head so they can breathe in and out when they are on the surface of the water. Since they are the only mammals that spend their entire lives in the water, and much of it underneath the surface, they are the only mammals to have a blowhole on top of their head. Most mammals have their nostrils in the front of their face, similar to human beings.
Is the whale a mammal or is it fishes?
Yes, Blue Whales are mammals.Blue Whales, and whales in general, form a group of mammals that live or spend a majority of their time in the water, known informally as aquatic mammals.
Can platypuses live in the water?
Platypuses must live on land (in burrows) but they hunt for food in the water. They are air-breathing mammals, but unlike whales and dolphins, they do not have a blowhole, so they cannot spend all of their time in water,
What are the nouns in this sentence. These mammals spend their entire life in the sea?
Nouns are people, places, and things. The nouns in your sentence are "whales," "fish," and "plankton."
What is a swimming mammel?
Whales, dolphins, porpoises, manatees, dugong, seals, walrus, and some otters. Characteristics are: Generally have a large size, hydrodynamic body (can go through water easily), and all the species have different marine life adaptions. They also have the characteristics of regular mammals. The cetaceans (Whales, dolphins and porpioses) and sirenians (manatees and dugong) are the most adapted. They spend no time out of the water; whereas the other species spend a little time on land.
What animals can swim?
There are numerous animals that swim. Many animals spend most or all of their lives in or on the water. These include fish, molluscs, and some crustaceans, of course, but also mammals (whales, seals, dolphins, hippos) and reptiles (snakes, eels, tortoises) and birds (penguins, ducks, pelicans), and some insects. There are only a few higher animals that cannot swim well.
Do mammals live on land or water or both?
Mammals evolved on land, and most still live on land. However, there are still a number that live exclusively in the water (such as whales, dolphins, manatees, etc) and many more that spend much of their time in water (such as beavers, seals, platypus, etc). One thing to note about aquatic mammals is they cannot get oxygen from water like fish, so they have to surface to breathe air frequently.
What are examples of fish mammals?
There are no "fish mammals". Mammals are mammals and fish are fish. Mammals are warm-blooded creatures with fur or skin, breathing through lungs, and feeding their yong on mothers's mlk, while fish are cold-blooded creatures covered with scales, and which breathe using gills. There are, however, mammals which live underwater and, like all mammals, suckle their young on mothers' milk. These are dolphins, whales, narwhals, dugong, manatees and porpoises. Then there are the mammals which actually live on land, but spend much of their time at sea, and so have adaptations in their limbs which act as fins. These include walruses, seals and sea lions,
Do mammals only live in water?
BECAUSE THEY WERE BORN LIKE THAT !lmfaooo. no I'm kidding.. i don't know how. I'm not a genius here..but their gills let them that's one (:Note: No mammal has gills after birth. They have an enhanced lung capacity, like whales, seals, polar bears, etc, that lets them hold their breath longer than other mammals can. They also tend to have a lot of blubber and protective fur, that allows them to survive the frigid temperatures of most aquatic habitats.Those animals that live in the water 24/7-- meaning that they never venture onto land, the way otters, beavers, etc, can-- are only able to sleep by 'turning off' portions of their brain at a time. A part of them rests, another part remains active and awake so that they don't sink below the surface and drown.
What is cetology?
Cetology is a science, which studies eight species of whales, dolphins, and porpoises. It is a branch of marine mammal science and focuses on these larger animals. The study of cetaceans can pose many difficulties as cetaceans spend only 10% of their time on the surface. They also do not leave tracks that can be followed. Numerous times this science consists mainly of watching and waiting.
Where do whales spend most of their lives?
in the water!
Why does being streamlined help a dolphin?
No, dolphins are mammals and mammals do not have scales. Reptiles are streamlined animals Yes. They are fast swimmers, and their torpedo shaped bodies allow them to manuever swiftly through the water.
