Mammal
The term 'mamífero' is Spanish for 'mammal'. Mammals are a group of vertebrate animals which form the class Mammalia. They distinguish themselves from other animal classes through the presence of mammary glands which in females produce milk for feeding their young, a trait evolutionary tied to the subclass Theria. Other key characteristics of mammals include their hair or fur, which helps to regulate their body temperature, and their highly advanced and specialized teeth.
