  • 1. The most advanced and modern among the animal kingdom

2. 3.

  • Mammalia - The young are nourished for a time by milk, or an analogous fluid, secreted by the mammary glands of the mother.
  • According to scientist at first milk was just used to moist eggs

4.

  • Domain -Eukarya
  • Kingdom-Animalia
  • Phylum Chordata
  • Class Mammalia

5.

  • Class Reptilia (Reptiles)
  • Class Aves (Birds)
  • Class Amphibia

6.

  • Humans are primates one of the orders of the class
  • The earliest mammal is Eozostrodon a rodent quite big over a meter long(2)

7.

  • Fur keeps the body warm helps for maintaining homeostasis
  • Mammary Glands -these organism feed their offspring withmilk all the nutrients needed by the baby
  • Three middle ear bones-transform sound vibrations into neural impulses(10)

8. Protection and survival

  • Immune system- systemof biological structures andprocesseswithin anorganismthat protects againstdiseaseby identifying and killing the intruders
    • White blood cells- cellsof theimmune systemdefending the body against bothinfectious diseaseand foreign materials
  • Physical adaptations- such asgood insulation , and by specialforms of behaviorsuch ashibernationandmigration cause of evolution(9)

9.

  • Armaments made of Keratin- horns, spines, and quills
  • Camouflage- use their natural coloring to blend in with their surroundings
  • Some mammals feed ingroupsin order to avoid predators
  • Alarm signals- some mammals use different signals in order to inform one another of upcoming danger(3)

10. Why move?

  • Skeleton structural support and movement support
  • Muscles strong myofibrils, attached to the bone to move it
  • Land mammalshave 4 legs (or 2 legs and 2 arms)
  • Water mammals- sleek, streamlined bodies
  • Mammals need to move toacquire food plants or other animals(4)

11.

  • Predators need to be faster and stronger to be able to kill
  • Victims need to be faster and smaller to be able to escape
  • Unique some have skin formed between their legs or fingers used for flying(7)

12. I think therefore I exist

  • Mammals have the most complex nervous system on the planet, with humans being the most advanced
  • Central nervous system (CNS)-the part of thenervous systemthatcoordinatesthe activity of all parts of the bodies
    • Brain -largest part of the central nervous system . Itregulatesmany different functions of the body of a mammal. The brainprocesses all incoming external stimuli , andtells the body what to do in response . In most mammals, these responses areautomaticandunconscious .
    • SpinalCord-linkingthe brain to the rest of the body(8)

13.

  • Peripheral nervous system (PNS)-made up of only connecting nerves
  • Somaticnervous system- controls both the muscles and the information that is processed by the skin and other receptors
  • Autonomic nervous system
    • Sympathetic nervous system - responsible forinitiating the flight or fight response , which prepares the body to handle dangerous situations
    • Parasympathetic nervous system- works toregain homeostasisafter the body has undergone a flight or fight response(8)

14.

  • Dolphins are some of Earths most famous mammals
  • They inhabit oceans worldwide
  • Their natural habitats include
  • bays, lagoons, rivers,
  • and coastal waters
  • Their diet consists mostly
  • ofsmallerfish (12)

15.

  • Locomotion: Do lph ins normally swim at23-25 mph
  • They swim fast and are able to swim on their bellies, backs, and sides; they can also jump quite high
  • Life cycle: Birth, calf, adult
  • Bottlenose dolphins can detect sound at extremely high frequencies unnoticeable by human ears(12)

16.

  • Cheetahs mostly inhabit the savannas of Southern and Western Africa
  • Their diet consists of calves, impalas, gazelles, antelope, and hares
  • The fastest land animal can run at up to 113 kmph in short
  • bursts due to its light
  • build, large heart,
  • and small amount of
  • stored fat(6)

17.

  • Cheetahs have special paw pads and retractable claws
  • Their large nostrils allow them to breathe in a bigger amount of oxygen
  • The small amount of fat they can store means they have little energy at hand
  • Life cycle: Birth, cub, adult
  • Often hunted down
  • because of their
  • beautiful fur(6)

18.

  • Brown bears reside in the mountains and forests of North America, South America, Europe, and Asia
  • Their diet consists of plants, fruits, nuts, insects, fish, birds, and mammals
  • Bears move with their metatarsals flat on the ground(11)

19.

  • Life cycle: Birth, cub, adult
  • Bears possess a sense of smell seven times as powerful as that of dogs
  • Bears powerful memory helps them relocate old food stashes
  • Bears are popular among children and are often mascots for various projects, like Smokey Bear(11)
