What are characteristics that all mammals share?

Answer 1

• Mammals are all warm blooded vertebrates with a covering of fur, skin or hair.
• All mammals suckle their young
• Most mammals give live birth, but there is a sub-group known as monotremes, which are the egg-laying mammals. This group includes just the platypus and the echidna. They are still mammals because, like all mammals, they feed their young on mothers' milk. Mammals also breathe through lungs.
• Mammals have a flexible neck with seven cervical vertebrae, and they show enhanced neocortex development
• Sound is produced by the larynx (a modified region of the trachea)
• Their limbs are oriented vertically
• The mammalian heart has 4 chambers
• Mammals have three middle ear bones
• They have a single lower jaw bone

Answer 2

All mammals are warm-blooded, tetrapod vertebrates: they maintain their body heat, have four limbs or fins, and have backbones. Most have seven cervical vertebrae. Almost all have hair or fur. The one requisite characteristic is that their females nurse their young with milk from their mammary glands.
they give birth to live young, they breast feed their young, and they typically have hair...yes even whales have hair follicles. They are warm blooded and have a back bones.
Live birth (as opposed to eggs), having hair or fur (as opposed to scales), being fed milk at early infancy (as opposed to bugs or whatever), warmblooded (as opposed to cold-blooded)

Mammals are

air-breathing animals whose females have mammary glands and males and females have sweat glands, hair and/or fur. Most mammals give birth to their young alive some species of mammals lay eggs (platypus)

They are characterized by the presence of sweat glands including those modified for milking
All mammals share the characteristic of having lungs to breathe, are warm blooded, and vertebrate. Most mammals also have hair to keep them warm.
All mammals have fur or hair, they are all warm blooded, and they are all fed milk produced by their mothers. Some, but not all, are born alive (the exceptions being the Platypus and the Echidna). Very few have bluetooth.
All mammals have fur or hair, and the babies all suckle their mother.
Mammals have teeth, three bones in the middle ear, mammary glands (females), are warm blooded, single lower jaw bone, body hair, diaphragm and a left aortic arch.
Because they are all born alive and they all have fur.

Answer 3

There are two essential characteristics shared by all mammals.

Firstly, they all have some form or fur or hair, whether it be a full coat, or just a few whiskers.

Secondly, they all feed their young on mothers' milk.

Many people believe all mammals give live birth. This is false, as there are three species of egg-laying mammals known as monotremes: the platypus, the short-beaked echidna and the long-beaked echidna. These mammals, like all other mammals and no other vertebrates or invertebrates, have fur and feed their young on mothers' milk.

Most mammals are also characterised by the following anatomical features:

- A flexible neck with seven cervical vertebrae

- Mammals also show enhanced neocortex development

- Sound is produced by the larynx (a modified region of the trachea)

- limbs are oriented vertically

- The mammalian heart has 4 chambers

- Internal temperature is generally high and constant

- Egg development occurs in the uterus (excluding Monotremata)

- RBC are non nucleated

- Diaphragm present between thoracic and abdominal cavities .

Answer 4

Too many to list. The only characteristics that are common in all mammals are that mothers produce milk and that at least some individuals grow at least a little hair (even whales have a little hair), plus characteristics we share with non-mammals, like bones and brains. Pretty much everything else is variable.

Answer 5

Humans are very similar to other mammals in a number of ways. For example, chimpanzees and humans share 96 to 98% of the same DNA depending on the study. We are also very similar in Biology, having many other same organs and reproduction cycles. We also share many behavior similarities like forming communities and social order, protecting our young, and forming relationships. We also eat many of the same foods, all need water to survive, and breath oxygen.

Answer 6

There are three types of mammals: monotremes. marsupials and placental.

The similarities are that they all are:

• warm blooded and can maintain a constant body temperature
  
• have hair or hair derived body coverings. Even whales have a few spare hairs
  
• have mammary glands although not all suckle their young
• related to the first mammals which evolved toward the end of the Triassic period from therapsids

The difference is in how they produce young. The monotremes like platypuses lay eggs, the marsupials like opossums and kangaroos have their young grow to a very primitive state then allow them to mature in a pouch, and the placental mammals have wombs to allow the young to grow internally until they are almost capable of external independent survival,

Answer 7

Warm bodies , they have fur to keep them warm.

Answer 8

Trick question. Remember the Duck Billed Platypus is classed as a mammal, and gives birth with eggs.

Answer 9

All mammals are warm blooded vertebrates. All mammals have hair. All mammals produce milk for their young.
