Kingdom Animalia
  • All animals are multicellular, mitochondrial
    heterotrophsthey have multiple cells with
    mitochondria and they rely on other organisms for
    their nourishment.
  • Most animals ingest their food and then digest it
    in some kind of internal cavity.

8
Animal Species
  • Somewhere around 9 or 10 million species of
    animals inhabit the earth.
  • About 800,000 species have been identified.

9
Animal Phyla
  • Biologists recognize about 36 separate phyla
    within the Kingdom Animalia.

Major Animal Phyla
11
Animal Movement
  • Most animals are capable of complex and
    relatively rapid movement compared to plants and
    other organisms.

12
Animal Reproduction
  • Most animals reproduce sexually, by means of
    differentiated haploid cells (eggs and sperm).
  • Most animals are diploid, meaning that the cells
    of adults contain two copies of the genetic
    material.

13
Animal Sizes
  • Animals range in size from no more than a few
    cells (like the mesozoans) to organisms weighing
    many tons (like the blue whale).

14
Animal Habitats
  • Most animals inhabit the seas, with fewer in
    fresh water and even fewer on land.

15
Animal Cells
  • Animal cells, like all eukaryotic cells, have
    internal structures called organelles that serve
    specific functions for the cell.
  • Animal cells lack the rigid cell walls that
    characterize plant cells.

17
Animal Bodies
  • The bodies of most animals (all except sponges)
    are made up of cells organized into tissues.
  • Each tissue is specialized to perform specific
    functions.
  • In most animals, tissues are organized into even
    more specialized organs.

18
Animal Symmetry
  • The most primitive animals are asymmetrical.
  • Cnidarians and echinoderms are radially
    symmetrical.
  • Most animals are bilaterally symmetrical.

19
Radial Symmetry
  • applies to forms that can be divided into
    similar halves by more than two planes passing
    through it.
  • Animals with radial symmetry are usually sessile,
    free-floating, or weakly swimming.

20
Bilateral Symmetry
  • applies to forms that can be divided into
    similar halves by only one plane passing through
    it.
  • Animals with bilateral symmetry are most
    well-suited for directional movement.

 
21
Radial vs. Bilateral Symmetry
22
Cephalization
  • Bilateral Symmetry usually has led to
    cephalizationthe process by which sensory organs
    and appendages became localized in the head end
    of animals.

23
Evolutionary Trends
  • If we analyze the basic body plans of animals, we
    find that they illustrate evolutionary trends.
  • Four major advances (in order)
  • Multicellular body plan
  • Bilaterally symmetrical body plan
  • Tube-within-a-tube body plan
  • Coelomate body plan

24
3 Major Bilateral Body Plans
  • Acoelomates
  • Pseudocoelomates
  • Coelomates
  • Each plan consists of 3 cell layers endoderm,
    mesoderm, ectoderm (triploblastic)

26
Acoelomates
  • These animals have no other cavity than the gut.
  • They are often called the solid worms.

27
Pseudocoelomates
  • These animals have a body cavity (the
    pseudocoelom) which is not completely lined with
    mesoderm.
  • The tube within a tube body plan.
  • This category is also composed of mostly worms.

28
Coelomates
  • These animals have a true coelom lined with
    mesodermal peritoneum.
  • Most animals are coelomate.

  • Deuterostomes anus first
