Β§  All amphibians are vertebrates, and they need moist environments or water to survive.

Β§  They are cold-blooded.

Β§  They absorb water and breathe through their thin skin.

Β§  They have at least one special skin gland used for defense.

Β§  Most follow the life cycle of egg-larva-adult.

 

Examples:

frogs

newts

salamanders

toads

Β§  Birds are a type of warm-blooded vertebrate that are adapted to fly.

Β§  Not all birds can fly, but they do all have wings.

Β§  Birds have beaks that help them catch and swallow food.

Β§  The digestive system of a bird allows it to eat whenever it can and digest the food later.

Β§  Birds lay eggs to reproduce.

Β§  They are endothermic, meaning they maintain their own constant body temperature.

Β§  They are bipedal, which means they have two legs.

Β§  They have hollow bones and their bodies are covered in feathers.

Β§  Birds belong to the class called Aves.

 

Examples:

parrots

penguins

pigeons

Β§  Fish are also vertebrates, and they are considered the oldest-known vertebrates.

Β§  They are ectothermic, or cold-blooded, which means they rely on their surroundings to regulate their body temperature.

Β§  Fish have fins.

Β§  Most, but not all, fish have bodies covered in scales and breathe through gills.

Β§  Fish live under water.

 

Examples:

salmon

seahorses

sharks

Β§  Mammals are another type of vertebrate that belong to the class Mammalia.

Β§  Young mammals get nourishment from milk produced by their mothers.

Β§  Most mammals have hair.

Β§  Their jaw is hinged directly to their skull unlike all other vertebrates.

Β§  Almost all mammals give birth to live babies.

Β§  They are endothermic, or warm-blooded.

Examples:

elephants

whales

humans

Β§  Reptiles are thought to be the first vertebrates to live completely on land. But, not all reptiles live only on land today.

Β§  They are cold-blooded, or ectothermic.

Β§  They lay eggs to reproduce.

Β§  They have four legs or descended from animals with four legs.

Β§  They breathe through lungs

Β§  Their bodies are covered in scales or scutes.

Examples:

crocodiles

snakes

turtles

lizards

Β§  Approximately 95% of all animals are invertebrates. Invertebrates do not have a backbone. There are different types of invertebrates, but they all share a few characteristics.

Β§  They are made up of many cells that work together, or multicellular.

Β§  Most, but not all, have tissues, cells that work together in a more complex way.

Β§  Most, but not all, can move.

Β§  There are over 35 phyla of invertebrates.

Β§  They generally have soft bodies.

 

There are eight phyla of invertebrates that are alive today.
