3. CHARACTERISTICS OF ANIMAL
CLASSIFICATION
• biologist have identified approx
1.4 million species, more than
third-fourth of animals
• Zoologist spend their lives group
animals according to their
characteristics, and their work
involves the study of lives of
organisms, their habbitat and
relationship with other orgainsms
• Approx 4 to 30 millions species
which are undescribed and much
work to discovering and classifying
the world

4. CHARACTERISTICS OF ANIMAL
CLASSIFICATION
• In 1995 R.M Kirstensen and P.Funch
of the unversity of copenhagen,
describe a new species called
SYMBION -PANDORA
• Symbion-Pandora is the
1. jug shaped
2. microscopicaquatic animal
3. present on the mouth part of
Norway Lobster
4. less than 1/2 mm wide,
5. Sac like body
6. different form in 3 stage of life cycle.

5. Symbion-Pandora
• This species is so different that is
arranged a new phylum called
CYCLIOPHORA

6. Classification of Organisms
• Organisms are classified by the specific name
• NAMEING SYSTEM IMPORTANCE
1. Reflect the order
2. show relationship that aries from evolutionary

7. SYSTEMATICS
is involved in the determination of evolutionary relationship of
organism
TAXONOMY
is involved in the classification and naming of organisms
NOMENCLATURE
is defined as a system of names and term used in a particular field of
study or community

8. TAXONOMIC CATEGORIES OF A
HUMAN AND A DOG
TAXON HUMAN DOMESTIC DOG
Domain Eukarya Eukarya
kingdom Animalia Animalia
phylum Chordata Chordata
class Mammalia Mammalia
order Primates Carnivores
family Hominidae Canidae
genus Homo Canis
species Sapiens Familiaris

9. A TAXONOMIC HIERACHY
INTRODUCTION
1. Introduce Modern Classification
by Karl Van Linane (Carolus
Linnaeus) IN (1707-1778)
2. His binomal system is still used.
3. Von Linane arranged the
spieces into different groups and
spieces are arranged by their
specific charactersitics.
4. Von Linane recoginzed 5 taxa.
5. Modern taxonomist use those 5
and add 3 other

10. A TAXONOMIC HIERACHY
• The taxa are arranged hierachically(from broad to specific)
DOMAIN
PHYLUM
SPIECIES
KINGDOM
FAMILY
CLASS
GENUS
ORDER
Although on Linnane did not accept evolutioin but many of his
grouping reflect evolutionary relatiopnship on the basis of their
characteristics

11. NOMENCLATURE
PROBLEMS OF USE COMMON NAMES OF ORGANISMS
1. Vary from country to country and from region to region in a country
2. Common names refer to taxonomic categorie higher than speieces level
SIGNIFICANCE OF BINOMAL NOMENCLATURE
1. Universal and clearly indicates the level of classification involved in any
description
2. No 2 Kinds of animals have same binomal name. the names are allotted
by “ INTERNATIONAL CODE OF ZOOLOGICAL NOMENCLATURE”

12. NOMENCLURE
• Nomenclature is tne combination of GENUS and SPECIES name of
organism
HOMO SAPIEN
GENUS SPECIES
THE NAME SHOULD BE WRITTEN UNDER-LINED OR LATINIZED
