Title: V' Kingdom Animalia


1
V. Kingdom Animalia A. Introduction 1.
Characteristics Eukaryotic Multicellular
Heterotrophic Lack cell walls.
2
V. Kingdom Animalia A. Introduction 1.
Characteristics 2. History - first animals
in fossil record date to 600 mya largely
wormlike soft-bodied organisms

V. Kingdom Animalia A. Introduction 1.
Characteristics 2. History - first animals
in fossil record date to 600 mya largely
wormlike soft-bodied organisms - in the
Cambrian, 550 mya radiation of most major
phyla seen today organisms with hard parts
radiation of predators

V. Kingdom Animalia B. Diversity 1.
Overview - Approximately 1 million
described animal species. Of these 5
have a backbone (vertebrates) ( a subphylum in
the phylum Chordata)

V. Kingdom Animalia B. Diversity 1.
Overview - Approximately 1 million
described animal species. Of these 5
have a backbone (vertebrates) ( a subphylum in
the phylum Chordata) 95 lack a backbone
(invertebrates) (in 29 Phyla, including
Chordata) 85 are Arthropods (insects,
crustaceans, etc.)
6
V. Kingdom Animalia B. Diversity 1.
Overview - Of the 29 Phyla, ALL but the
arthropods and Chordates have more
marine/aquatic species than terrestrial
species. - So, most animal life is
invertebrate and/or marine. humans are
not a typical animal vertebrates are
not typical animals

V. Kingdom Animalia B. Diversity 2.
Evolutionary Trends a. Body
Symmetry asymmetrical radially
symmetrical bilaterally symmetrical
8
V. Kingdom Animalia B. Diversity 2. Trends
a. - Body Symmetry b.
Cephalization (evolving a head)

V. Kingdom Animalia B. Diversity 2. Trends
a. Body Symmetry b. Cephalization
(evolving a head) c. Digestion -
intracellular to extracellular - evolution of a
digestive system (important to heterotrophs
that have to EAT)

V. Kingdom Animalia C. Major Phyla 1.
Sponges
11
V. Kingdom Animalia C. Major Phyla 1.
Sponges Protist links Choanoflagellates and
choanocytes
12
V. Kingdom Animalia C. Major Phyla 1.
Sponges Protist links Choanoflagellates and
choanocytes Multicellular, with specialized
cells, but loosely integrated (the blender
phenomenon).
13
V. Kingdom Animalia C. Major Phyla 1.
Sponges Protist links Choanoflagellates and
choanocytes Multicellular, with specialized
cells, but loosely integrated (the blender
phenomenon). Asymmetrical
14
V. Kingdom Animalia C. Major Phyla 1.
Sponges Protist links Choanoflagellates and
choanocytes Multicellular, with specialized
cells, but loosely integrated (the blender
phenomenon). Asymmetrical Filter feeders with
intracellular digestion choanocytes absorb,
amoebocytes distribute, spicules provide
structural support.

reproduction (fragmentation)
