Vertebrates: Mammals


People are mammals.  So are dogs, cats, horses, duckbill platypuses, kangaroos, dolphins and whales. Among all the mammals, Humans are among the most numerous of the large mammals. Know what you all have in common?

 
The answer is – MILK!  If an animal drinks milk when it is a baby and has hair on its body, it belongs to the mammal class.
 
 




Mammals are animals that nourish their young with milk produced by females. Females of the mammal animals have mammary glands. Mammals are also characterized by the presence of body hair. They are generally warm-blooded vertebrates. Lions, tigers, and whales are some common mammals.
