Zoology

• 'zoion' means "animal" and

  'logia' means "to study"
• Zoology

  also known as animal

  science is the branch of biology

  devoted to the study of animal life.
• Zoology


  the branch of biology

  that studies the animal kingdom,

  including the structure, embryology,

  evolution, classification, habits, and

  distribution of all animals, both living

  and extinct, and how they interact

  with their ecosystems.
• Taxonomy


  which means

  “arrangement law”
• Taxonomy 


  is the science of

  classifying organisms to construct

  internationally shared classification

  systems with each organism placed

  into more and more inclusive

  groupings.
• Carolus Linnaeus


  a Swedish

  botanist, zoologist, and

  physician, which uses a

  hierarchical model.
• Taxonomic

  Classification System


  also called the Linnaean

  system
• who invented the Linnaean System or Taxonomic Classification System

  Carolus Linnaeus

• Binomial Nomenclature


  Naming of organisms using 2

  names
• Binomial Nomenclature


  It consist of 2 epithets (words)

  (Genus and Species)
• Binomial Nomenclature 


  It was first introduced by

  Linnaeus in1751.
• How to write?

  1. Genus should come first
  2. Species follows next
  3. Should be in Greek or Latin
  4. The name should relate the organism
  5. 1st letter of genus should be in CAPITAL LETTER.
  6. Species should be in small letter.
  7. It should be italicized or underlined
• Kingdom Animalia 


  also known as Metazoa, comprises a broad range of animal species, from tiny parasitic nematodes and microscopic invertebrates to the largest of mammals -- the blue

  whale.
• the exact number of members of kingdom Animalia is unknown and difficult to guess; there are over one million estimated insects alone. Though the kingdom is diverse and large, all animals share a distinct set of characteristics.
• There are some animals that

  can reproduce both asexually and

  sexually.

  Animal Reproduction
• Asexual reproduction

  produces genetically identical

  copies (ex. clones)
• sexual

  reproduction produces

  genetically unique offspring.
• A very common type of asexual

  reproduction especially in colonial

  animals.

  budding
• In budding a new

  offspring begins as an outgrowth

  of the parent and may either

  remain attached and form a colony

  or break away and begin an

  independent life.
• Fragmentation


  Some animals spontaneously

  break into many separate pieces

  which then regrow into a

  complete animal.
• Regeneration 


  This process is most commonly used

  not just as a form of reproduction but also to replace missing or damaged parts.
• Regeneration


  Some organisms have great powers of

  regeneration while others can only

  regenerate simple cells and tissues.
