Class
Five major classes of chordata
Fish (Pisces)
Live in fresh water or sea water
Body is covered with slimy scales
Fins and tails are used to swim and balance the body
Breat through gills
Cold-blooded
Lay eggs
Amphibians (Amphibia)
Can live on land and in the water
Have moist and exposed skin
Cold-blooded
Lay eggs
Have webs
Do not have external ears
Reptiles (Reptilia)
Have dry and scaly skin
Most lay eggs
Cold-blooded
Breath through lungs
Have one type of teeth
Teeth are sharp and cone-shaped
Birds (Aves)
Live on land
Covered with feathers
Feathers are waterproof and can trap heat to keep the body warm
Can swim and fly
Lay eggs
Warm-blooded
Breathe through lungs
Use beak instead of teeth
Hard scaly legs and sharp claws
Mammals (Mammalia)
Most live on land
Covered with hair or fur
Skin has swat glands
Warm-blooded
Breathe through lungs
Order
Family
Genus
Species
A group of organisms which can interbreed and produce fertile offsprings
The smallest taxonomic group, though many subspecies are recognized
D Kings Play Chess On Fine Grain Sand
Dichotomous key
A method of identification where by group of organisms are divided into two categories repeatedly
It is preferable to use immutable features
Natural Classification
Groups together species that share a common ancestor from which they evolved
Darwinian principle of common descent
It is very helpful when dealing with new species
Non-vascular Plants
Vascular Plants
