Mammals nona emi yanko 10 5

  1. 1. Mammals Presentation Created By: Emi Buchinska Yanko Hristov Nona Stancheva
  2. 2. How can we recognize a mammal? <ul><li>Produces milk for its children (if the animal is female) </li></ul><ul><li>Has hair – all even dolphins and whales – because of their mustache </li></ul><ul><li>Lower jaw – consists only of a single jaw </li></ul><ul><li>Has 3 bones in the ears – stapes, incus, malleus (they were once a part of the jaw, but during evolution period – became parts of the ears) </li></ul><ul><li>Has only one main artery that curves to the left side of the heart and becoming aortic arch </li></ul><ul><li>Has diaphragm (muscle+tendon that separates the body in 2 parts) [2] </li></ul>
  3. 3. What does the word mammal mean? (Word Origin) <ul><li>Mammalia/mammalis (in Latin) </li></ul><ul><li>– comes from the word mamma – meaning mother [6] </li></ul>
  4. 4. Symmetry <ul><li>3 kinds of symmetries – – radial, asymmetrical & bilateral </li></ul><ul><li>Mammals – bilateral - if we cut the animal in the middle of its body the 2 parts are going to be almost the same looking – symmetrical body </li></ul>
  5. 5. Naming mammals! <ul><li>Kingdom - Animalia </li></ul><ul><li>Phylum – Chordata </li></ul><ul><li>Subphylum – Vertebrata </li></ul><ul><li>Class - Mammalia </li></ul><ul><li>Subclass - Prototheria; Metatheria; Eutheria </li></ul>
  6. 6. Dolphins/Delphinus (by Yanko!) <ul><li>Live in seas, oceans, rivers (in ¾ of the seas in the world) </li></ul><ul><li>Different food (mostly small fish) – big dolphins need 10-15kg </li></ul><ul><li>Quickest – 35km/h </li></ul><ul><li>Adult Dolphins  Reproduction  Baby Dolphins </li></ul><ul><li>Interactions with humans [8] </li></ul>
  7. 7. Foxes/Fukh <ul><li>Europe, Asia, North and South America </li></ul><ul><li>Mostly in the forests </li></ul><ul><li>Have some kind of a diet – different food to function well </li></ul><ul><li>Almost invisible – very quick! </li></ul><ul><li>35-40 inches long </li></ul><ul><li>Winter  Mating Season; Autumn  Dispersal Season; Spring  Moult and Birth Season; Summer  Area Spreading [7] </li></ul>
  8. 8. Bats/Chiroptera <ul><li>in all continents in the world (in the forests, also in caves) </li></ul><ul><li>Most eat insects </li></ul><ul><li>some eat mice and other animals with the size of a mouse </li></ul><ul><li>can’t function properly during the daylight </li></ul><ul><li>Adult ( 1 year bat)  Baby Bat ( Can’t stand alone)  Baby Bat (Can Stand)  Teen Bat ( Can Fly) </li></ul><ul><li>Rabies – disease able to cause heart attack, coming from bats [9] </li></ul>
  9. 9. Reproduction in mammals <ul><li>- internal fertilization- embryo develops inside the mother’s body </li></ul><ul><li>- smaller animals- shorter gestation, larger animals- longer gestation </li></ul><ul><li>- 3 phases of gestation: </li></ul><ul><li>1) development of the embryo </li></ul><ul><li>2) d evelopment of the fetus (the embryo in its later stages of development ) </li></ul><ul><li>3) birth of the fetus [1] </li></ul>
  10. 10. Obtaining and digestion of food <ul><li>- herbivores- feed on plant materials </li></ul><ul><li>- cellulose- hard for digestion; mammals lack specialized enzymes </li></ul><ul><li>- digestion takes place with the help of microbes; cellulose is broken down in the internal flora </li></ul><ul><li>- carnivores </li></ul><ul><li>- can go for several days without food </li></ul><ul><li>-omnivores [4] , [3] </li></ul>
  11. 11. Movement <ul><li>- mammals are capable of walking big distances </li></ul><ul><li>- homeothermic body (warm blood) </li></ul><ul><li>- when running/walking, legs move back and forth beneath the body </li></ul><ul><li>- movement is possible because of tendons </li></ul><ul><li>- the back stores energy </li></ul><ul><li>- different types of movement (walking/running/flying/swimming/jumping/crawling, etc.) [3] </li></ul>
  12. 12. Vocabulary <ul><li>Abundant – Common , Rich, Have a lot of </li></ul><ul><li>Rabies – A disease which can cause heart attacks </li></ul><ul><li>Herding – Hunting by a whole group surrounding the victims </li></ul><ul><li>Moult – change of feathers </li></ul><ul><li>Bilateral – symmetrical </li></ul><ul><li>Asymmetrical – opposite to bilateral </li></ul><ul><li>Radial – in a round shape </li></ul><ul><li>Viviparous- giving birth to living offsprings </li></ul><ul><li>Gestation- pregnancy </li></ul><ul><li>Fetus- the embryo in its later stages of development , right before it is born </li></ul><ul><li>Homeothermic- having warm blood </li></ul>
