CLASSIFICATION OF MARINE
SPECIES
World is so diverse
Classification
 The grouping of information or objects based
on similarities
 We classify things all the time (creates order)

Classification
 Taxonomy
branch of biology that
names and groups organisms
A good classification system
 Places organisms in a group with other
similar organisms
 Uses names that are unique
 Can change as new data is discovered
 Shows relationships between organisms
ARISTOTLE
What is this?

 Pacific spiny lobster
- rock lobster
-crayfish
Can get confusing.
Real name is Panulirus interruptus
What is this called?
Common Names
 Pill bug
 Sow bug
 Roly polies
 Wood lice
 Potato bug
………..all are common names for same bug
Scientific name: Armadillidium vulgare
Need for naming system
 We need to be able to identify/name each
species
 Common names: confusing
 Scientific names: refer to one species ONLY
that everyone uses
Carolus Linnaeus
Swedish
botanist who
devised a new
classification
system
This system is
still used
today!
The Linnaeus System
 Organisms are grouped in a hierarchy of 7
different taxonomic levels
or Taxons
 Each organism has a two part scientific name
=Binomial Nomenclature
Linnaean System
 Hierarchical classification using seven
categories or taxa, listed in order from
largest to smallest groupings: (Domain
was later added before kingdom)
