Scientific Taxonomy

Is the science of identifying and naming species, and arranging them into a classification.

We use groups called “taxa” to organize organisms based on similar characteristics.

Humans Are Vertebrates!

Animals With Backbones- Chordates

(Phylum Chordata)

MAMMAL

FISH

REPTILE BIRD

AMPHIBIAN

Vertebrates- have a backbone.

phylum chordata.

Vertebrates include many different kinds of animals and are found just about everywhere

– in oceans, rivers, forests, mountains, and deserts.

Only 5% of the kinds of animals on earth are chordates.

Animals With Backbones

Fish

Fish Characteristics Largest group of vertebrates.

Many fish are covered with scales that protects them.

Have fins for steering and balance in the water.

They breathe through gills.

Ectotherm- means “outside temperature”. Means Cold blooded, their body temp is regulated by the temp of the water.

Amphibians

Amphibian Characteristics Their body temperature varies with their

surroundings. Ectotherm- means cold blooded.

Amphibians hatch from eggs and they can live on land as an adult.

Young amphibians breathe through gills like fish.

Adult amphibians breathe air from lungs.

Amphibian Characteristics

This process of change from baby to adult is called a metamorphosis.

Some have smooth moist skin.

Examples- Frog, toad, newt, salamander.

Reptiles

Reptile Characteristics

They lay eggs on land and undergo no metamorphosis.

They have dry scaly skin.

They can include animals as large as a crocodile and as small as a gecko.

Ectothermic.

They live in hot, dry deserts and in warm, wet tropical rain forests.

Examples- turtles, snakes, iguanas, lizards.

Birds

Bird Characteristics

Have wings, beaks, 2 legs and feathers. Only birds have feathers.

Endotherms- “inside temp” body regulates temperature.

There are about 9,000 types of birds.

The bird’s skeleton is very light in weight. Bones are hollow! This helps them to fly.

Examples- flamingo, eagle, sparrow, crow, owl, hawk.

Mammals

Mammal Characteristics

Humans are mammals.

Their young grows inside the mother – give birth to live young

They feed milk to their young.

Hair is an adaptation that keeps mammals warm.

They are endotherms- maintain a constant body temperature.

-ape, lions, kangaroos, bats, and your mom.

Ticket to Leave

On a sheet of lined paper, Write down the difference between a endotherm and an ectotherm.

Similarities and difference between anphibians and reptiles.

Also, write the names of the scientific taxonomic levels in order.
