MammalsWhy are we called Mammals?
Mammals are warm-blooded, usually have hair or fur,
and nourish their young with milk
Happy to report that there are so many mammal species
Look at the photos below and figure out which one is mammal and which one is not
There are different types of mammals:|
A) Placental mammals
These are the best known mammals. Before birth, the baby is nourished through a placenta, a specialized embryonic organ that is attached to the mother's uterus and delivers oxygen and nutrients to the baby. A famous placental mammal is the homo sapiens = human being

Marsupials are born extremely immature. Most female marsupials have pouches, where the newborn crawls in and grows. A famous marsupial mammal is the Kangaroo
Monotremes fossils can be over 50 million years old. Monotremes lay eggs, but nourish their babies with milk. Today we know of the echidnas and the duck-billed platypus as monotreme mammals.
Now look at the photos below: Sometimes you see 2 mammals,|
Sometimes you see a mammal and another kind
There are two photos of Monotreme mammals
If you know them all: GREAT - if not, not a problem: just send us an email!
