Yes, there are about 5740 give or take a few but I'm still working on it and its the classification of all mammals, I only have even and odd toed ungulates, pangolins, sloths and carnivores left.
a few but not all and i only have one to share with you, the bat
No! Most mammals give birth the same way except for the platypus which lays eggs and all other mammals give live birth
push it out Pepsi_dog: beavers are mammals, therefore as all mammals give birth.
Guinea pigs are mammals. All animals with fur and give milk are mammals.
No they don't, they give birth. As do all Mammals, and bunnies are mammals.
There is no such thing as giving birth internally. Do you mean, "Do mammals give live birth?" All mammals but the five species of monotremes give live birth.
Yes, because they are mammals, and all mammals give birth to live offspring.
Yes. All mammals give birth to their young alive. The babies are not born from eggs. Mammals only give birth to alive babies.
All mammals have backbones - this is part of the definition of a mammal. Therefore, a complete list of all named mammals (well over 4000 different species) would be a complete list of mammals with backbones.
Hares are mammals. All mammals give birth to live young.
The answer is "all mammals give birth to live young". Though today we know that is not entirely true. For example, the platypus is a mammal and it lays eggs.
The logic would be. All dogs are mammals All mammals give birth to live young. Therefore dogs give birth to live young. The problem with this is that monotremes, which are mammals lay eggs. Other than that, this is the correct format.
