These glands are present nearlly in every mammal:
1-Scent Glands.
2-Sebaceous Glands.
3-Mammary Glands.
There are hundreds of mammals in Africa. Three of the most common and diverse are the common rat, the zebra and the duiker, a small antelope.
A rat has three vena cavas while most other mammals like humans only have two.
Australia has many mammals (most of which are marsupials) that eat insects. They include:numbatsechidnas (a monotreme, not a marsupial)possums and glidersdunnartsplanigalesphascogales
The three types of mammals are:Placental mammals, or Eutherians. This is the largest group of mammals.Marsupials (often referred to as the "pouched mammals")Monotremes, or egg-laying mammals
The three most common factors among mammals are that they all breathe air, have red oxygenated blood, and all feed and protect their young.
All mammals feed their young with milk, have hair, have a neocortex region of the brain, and have three middle ear bones. There are other characteristics shared by all mammals, but the above four are (for the most part) that only ones unique to mammals.
Alive**********************Most mammals are born fully formed [infant version of the adults] and do not hatch from eggs.Most mammals are born alive.There are two egg-laying mammals. The platypus and the echidna are both egg-laying mammals, or monotremes.They are still classified as mammals because they feed their young on mothers' milk - a characteristic unique to mammals alone.There are just three known species of egg-laying mammals, or monotremes. They are the platypus and short-beaked echidna (Tachyglossus aculeatus) of Australia, and the long-beaked echidna (Zaglosssus bruijni) of Papua New Guinea. The echidna is sometimes called the spiny anteater, and there are several sub-species of the long-beaked echidna: the Western long-beaked echidna, Sir David's long-beaked echidna and the Eastern long-beaked echidna.
Most mammals are placental. In Australia, however, almost all mammals are marsupials.
Mammals are warm-blooded vertebrates.They have a covering of skin or hair/fur.All mammals suckle their young with mothers' milk.The young of most mammals are born alive, except for monotremes - the platypus and echidna - which lay eggs.There are three main groups of mammals: placental, marsupial and monotreme. Monotremes are the egg-laying mammals. Marsupials are characterised by giving birth to undeveloped young which, in most species, must then develop in a pouch.
Three herbivors that are not mammals are snails, aphids, and moths.
Most mammals do not hatch from eggs. However, there is a small group of egg-laying mammals which are known as monotremes. There are just three known species of monotremes: the platypus; the short-beaked echidna; and the long-beaked echidna.
placental mammals are the most famous mammals
