  1. 1. Mammals Aleks Popov Atanas Radovanov Yana Stoyanova 10/6
  2. 2. Mammals Characteristics <ul><li>Any of a class of higher vertebrates whose bodies are covered with hair, who give birth to live young, nourishes their young with milk from mammary glands ( the name mammals comes from them ), regulate their body temperature internally, have four types of well-developed teeth and typically have four well-developed legs with toes that have nails, claws or hoofs. (www.ncforestry.com) </li></ul><ul><li>Bilateral symmetry </li></ul><ul><li>-the organism can be divided </li></ul><ul><li>into two equal parts and can move </li></ul><ul><li>freely </li></ul><ul><li>( http://www.thefreedictionary.com/ </li></ul><ul><li>bilateral+symmetry) </li></ul><ul><li>( http://upload.wikimedia.org/wikipedia/ </li></ul><ul><li>commons/a/a5/Mam%C3%ADferos.jpg ) </li></ul>Image from: http:// www.ucmp.berkeley.edu/phyla/phyla.html
  3. 3. Their Place in the Evolutionary Three <ul><li>Mammals, or Mammalia are a class in the Phylum Chordata and the Subphylum Vertebrata. </li></ul><ul><li>There are 3 Subclasses within the class Mammalia: </li></ul><ul><li>Prototheria or Monotremes (2 species) (lay eggs) </li></ul><ul><li>Metatheria or Marsupials (275 species) (carry their young through early infancy) </li></ul><ul><li>Eutheria or placental mammals (3982 species) (carry their young in a placenta and nurture after birth) ( www.earthlife.net ) </li></ul>
  4. 4. Characteristics unique to Mammals <ul><li>A female mammal uses its mammary glands to produce milk and feed it’s young </li></ul><ul><li>Mammals posses hair in the form no other animal does </li></ul><ul><li>The lower jaw in mammals is a single bone on either side </li></ul><ul><li>Only the mammal middle ear contains 3 bones. </li></ul><ul><li>In mammals the main artery leaving the heart curves to the left becoming the aortic arch </li></ul><ul><li>mammals have a diaphragm </li></ul><ul><li>( www.earthlife.net ) </li></ul>( www.earthlife.net )
  5. 5. Characteristics of life of mammals <ul><li>Reproduction </li></ul><ul><li>Sexually </li></ul><ul><li>With care of the young for a long amount of time </li></ul><ul><li>Life Cycle </li></ul><ul><li>- Three stages-before birth, young and adult </li></ul><ul><li>Eating system </li></ul><ul><li>Before birth: from the placenta </li></ul><ul><li>After birth: with the help of the digestive system </li></ul>
  6. 6. Characteristics of life of mammals <ul><li>Life Cycle Digestion </li></ul>http://www.cloudforestvoices.com/CFVimages/Cheetah-6-web.jpg http://www.whathealth.com/lymedisease/images/tick-lifecycle.jpg
  7. 7. Chimpanzees ( Pan troglodytes ) <ul><li>Latin name : Pan troglodytes; Phylum: Chordata ; Class: Mammalia ; Order: Primates; Genus: Pan </li></ul><ul><li>anthropoids </li></ul><ul><li>They life mostly in one continent, Africa, and there in savannas and tropical forests. </li></ul><ul><li>Generally they eat plants, but also some small animals are sometimes included in their daily meal </li></ul><ul><li>Live in groups, each member has a specific function </li></ul><ul><li>Move via their legs and arms using them for both climbing and walking </li></ul><ul><li>Have an interaction on both the animal and plant life of the areas which they inhabit </li></ul><ul><li>http://www.solarnavigator.net/animal_kingdom/mammals/chimpanzee.htm </li></ul><ul><li>http://rc-anodizing.tripod.com/PEZT/animalsZT/chimpanzee.htm </li></ul>
  8. 8. Cat ( Felis catus ) <ul><li>phylum:chordata; class:mammalia; order Carnivora ; family:felidae ; genus: Felis; </li></ul><ul><li>The most popular and abundant animal in the world – can be found everywhere (including Antarctica) </li></ul><ul><li>Cats hunt small prey; when the cat has an owner it is free-fed (eats meat) </li></ul><ul><li>Move using their four legs </li></ul><ul><li>One of the most invasive species; can lead to the extinction of some smaller animal (birds for example) </li></ul><ul><li>Blind, deaf, almost without any fur  start to see, taste, hear  after 7 moths they are enough mature to live on their own </li></ul><ul><li>http://www.simplepetcare.com/pet-pets/2/CAT/ </li></ul>
  9. 9. African Bush Elephant ( Loxodonta africana ) <ul><li>Phylum: chordata; Class:mammalia; Order:proboscidae; Family:Elephantidae; </li></ul><ul><li>Can live in a diverse range of ecosystems </li></ul><ul><li>Elephants are herbivorous </li></ul><ul><li>Can grow up to 7.5 meters </li></ul><ul><li>Move via their 4 legs; do not have a wide range of movements </li></ul><ul><li>Can be both beneficial and harmful for the nature </li></ul><ul><li>They are born as small as 115 kg, but can reach up to 6.5 tons (the average is 4.6 tons) </li></ul><ul><li>http://www.seaworld.org/animal-info/info-books/elephants/scientific-classification.htm </li></ul>
  10. 10. Interaction of Mammals with Humans <ul><li>We contribute to both the preservation and extinction of some species </li></ul><ul><li>Their meat and products are used as food for us </li></ul><ul><li>An important source of proteins and fats </li></ul><ul><li>Their skins and fur is used in the production of clothes </li></ul><ul><li>We use some of them (such as horses) for transportation and farming work </li></ul>http://www.teepeeheart.onlinehome.de/cattle.jpg
