<ul><li>1.Mammals Presentation Created By: Emi Buchinska Yanko HristovNona Stancheva</li></ul> <p>2. How can we recognize a mammal? </p> <ul><li>Produces milkfor 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> <p>3. What does the word mammal mean? (Word Origin) </p> <ul><li>Mammalia/mammalis (in Latin) </li></ul> <ul><li>comes from the word mamma meaning mother [6] </li></ul> <p>4. Symmetry </p> <ul><li>3 kinds of symmetries radial, asymmetrical&amp;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> <p>5. Naming mammals! </p> <ul><li>Kingdom-Animalia</li></ul> <ul><li>PhylumChordata </li></ul> <ul><li>SubphylumVertebrata </li></ul> <ul><li>Class -Mammalia</li></ul> <ul><li>Subclass -Prototheria; Metatheria;Eutheria </li></ul> <p>6. Dolphins/Delphinus(by Yanko!) </p> <ul><li>Live in seas, oceans, rivers (in 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 DolphinsReproductionBaby Dolphins </li></ul> <ul><li>Interactions with humans [8] </li></ul> <p>7. Foxes/Fukh </p> <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>WinterMating Season; AutumnDispersal Season; SpringMoult and Birth Season; SummerArea Spreading [7] </li></ul> <p>8. Bats/Chiroptera </p> <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>cant function properly during the daylight </li></ul> <ul><li>Adult ( 1 year bat)Baby Bat ( Cant 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> <p>9. Reproduction in mammals </p> <ul><li>- internal fertilization- embryo develops inside the mothers 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> <p>10. Obtaining and digestion of food </p> <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 theinternal 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> <p>11. Movement </p> <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> <p>12. Vocabulary </p> <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> <p>13.
