Hair and milk.
First, our spines make us vertebrates. Giving live birth, and female milk glands are two features that make us mammals.
Two notable features that mammals have in common are that they all give birth to live young and they all have hair. Another thing that most mammals have in common is that the females make milk to feed their young.
They have fur and feathers for body covering are slightly the same
Mammals have several different external features that make them different from other animals. Some of these features include body hair or fur, external mammary glands, and warm-bloodedness.
Bats are flying mammals. All mammals are vertebrates because they have a vertebral column (backbone) and internal skeleton which are some of the main characteristics of a vertebrate. Therefore, Bats are vertebrates.For more information about vertebrates and invertebrates see related questions.
vertebrates which can maintain their body temperature and do not change their body temperature according to the external environment are called as warm blooded animals such as mammals and birds:.)
Ostrich are not able to fly and are enormous. They are not the most intelligent bird. Their bodies are huge but their brains are peanut sized.

Animals with backbones (a spine) make up veterbraes, this includes most animals species but it does not include any insects or sponges. What it does include is mammals, birds, fish, reptiles and amphibians.
The two major groupings within the animal kingdom are invertebrates (animals without a backbone) and vertebrates (animals with a backbone). Invertebrates make up the majority of animal species and include insects, worms, and mollusks, while vertebrates include mammals, birds, reptiles, amphibians, and fish.
Seals are mammals because they breathe air, bear live young, and are red (warm) blooded.
