Mammals are unlike other vertebrates in two distinct ways. First,all mammals have hair, unlike other vertebrates. Also, most femalemammals carry their offspring to full term i…n the uterus, whereasmost other vertebrates lay eggs. Monotremes are an exception.
some have back bones and the others dont
What makes you a mammal? . You need to be hairy. All mammals have this distinguishingfeature. . You need to have modified sweat glands that produce milk foryour young. Assum…ing that you are a female, of course. . Your lower jaw has a single bone on either side. Most otheranimals have several bones in the jaw. . Your hearing is acute because you have three bones in yourmiddle ear; the stapes, incus and malleus. . You have a sheet of muscle that separates your heart and lungsfrom your liver,stomach,kidney and intestines. This is called adiaphragm. This helps in rapid locomotion but also means you arethe only kind of animal that can get a hernia(torn diaphragm).
The presence of a backbone (a "vertebrae") does not DEFINE a mammal because other animals also have backbones, eg reptiles, birds and fish - these animals are also "vertebra…tes". Mammals are mammals because they are the only animals to have fur/hair and feed their young on milk.
Mammals, along with birds, are warm-blooded. Along with reptiles and birds, they are amniotes. Mammals are unique among vertebrates in that they have hair somewhere on their b…odies, feed their young with milk, and give live birth (except for the five species of monotremes). Placental mammals (about 90% of mammals) are unique in that they nourish their young in a placenta before giving birth.
Mammals are the only ones that can have fur or hair over their skin. Birds have feathers. Amphibians have moist skin. Reptiles have scaly skin. Fish have scales.
mammals have hair all over their bodies, they give birth to live young, they include the largest animal ever-the blue whale
Echidnas are different as, like platypuses, they are egg-laying mammals. This group of vertebrates, known as the monotremes, is unique: their method of reproduction is laying …eggs, yet they nurture their young on mothers' milk. Apart from producing milk to feed their young, there are other differences: they do not fit with egg-laying reptiles as echidnas are warm-blooded; nor do they fit with egg-laying birds because all birds have feathers, and echidnas, like other mammals, have hair/fur.
All breeds of horse, not just Arabians have the fastest reaction time of any animal, domestic or wild. This has been their main survival tool since they became single toed gra…zers. There are other things that make them different, but this is the main one.
they swim in both water and walk on land
The defining characteristic of a mammal is that it feeds its young on mothers' milk . This is the case whether the mammals is a placental, a marsupial or a monotreme (egg-lay…ing mammal).
Only mammalian kidneys have a renal pelvis (dilated beginning of the ureter) and renal pyramids (8 to 18 cone-shaped tissues in the renal medulla). The renal medulla (the inne…rmost part of the kidney), and the renal cortex (surrounds the renal medulla) are more distinguishable in mammals than in other vertebrates.
In Animal Life
All mammals including woolly mammals are different from other vertebrates in possession of hair ,wool is also type of hair .
they produce young from the womb and they have hair or skin
The most obvious way in which mammals differ from the other four classes of vertebrates is that mammals nurture their young on mothers' milk.
Mammals have two unique characters that differentiate them from other vertebrates.They are: 1.Mammary Gland 2.Hair.
