5th Grade Animal Classification

echinoderm

"spiny-skinned" invertebrates. They have several arms . They have no heart, brain, nor eyes, but some brittle stars seem to have light sensitive parts on their arms.

exoskeleton

A rigid external covering for the body in some invertebrate animals, especially arthropods, providing both support and protection.

mammal

A type of warm-blooded animal that breast feeds their babies and usually has hair.

amphibian

An animal that typically begins life in water, then moves to land. • Live in water and land and breathe with gills when they are young. • As they become adults, they begin to spend more time on land. • Breathe with lungs when they are adults All amphibians are cold-blooded Examples: Salamanders, newts, frogs, toads

invertabrate

An animal without a backbone

warm-blooded

Birds and mammals maintain constant internal body temperatures. Their body cells produce enough heat to keep their bodies warm even when the temperature outside their bodies is very low.

mollusk

Clams, oysters, snails, squid and octopus. These animals have soft bodies and most have shells. They live, eat and move in many different ways.

Animals on earth

Invertabrates = 10% Vertabrates = 90%

Amplhibians

Live in water and breathe with gills when they are young. Grow up and spend more time on land, breath with their lungs. Cold blooded.

Reptiles

Live on land, breathe with lungs. Have scales, live in warmer climates, reproduce by eggs and cold blooded.

arthropod

Lobsters, crabs, spiders, and insects are examples of animals that have exoskeletons. This is the animal group with the most species.

What traits do fish have?

Most have a bony skeleton, but some, such as sharks, have a skeleton that is only cartilage. They have gills that allow them to breathe in water. • They have scales to protect their bodies • Cold-blooded (same temperature as surroundings)

cold-blooded

Reptiles, amphibians, and most fish are animals whose body temperature depends on the temperature outside their bodies.

Why do scientists classify (sort) plants and animals into groups?

Scientists classify animals so they can easily identify, sort, and name living things.

bird

These animals have wings that allow them to fly and feathers. Along with aiding in flight, feathers help birds keep body heat. Most species have light bones.

What is another name for a carnivore?

a carnivore is also known as a "meat eater"

What is an insect?

a small animal that has six legs and a body formed of three parts and that may have wings

What are omnivores?

animals that eat food from both plants and animals, which may include eggs, insects, fungi and algae; many rely on both vegetation and animal protein to remain healthy

What are carnivores?

animals that feed on flesh

What are vertebrates?

animals that have a backbone

What are invertebrates?

animals that lack an internal skeleton or bones

Vertebrates have ___________________________________.

backbones (spine)

examples of birds

blue jays, falcons, parrots, flamingos

decomposers

break down organic matter; example: mushrooms

examples of fish

clown fish, shark, goldfish, salmon

examples of mammals

dog, human, cats, dolphins

consumers

eat other living things for energy; example: animals

One way scientists use groups for living things is by how they use _______ for ________.

food for energy

examples of amphibians

frog, toad, newt, salamander

What are arthropods?

invertebrates that have an exoskeleton (external skeleton), a segmented body, and jointed appendages (paired appendages)

mammals

living things with vertebra, hair or fur, gives birth to babies, feed the babies milk form their bodies & warm blooded

producers

make their own food; examples: trees, bushes & flowers

birds

may or may not fly, with vertebra, lay eggs, have feathers and warm blooded

examples of echinoderms

sea stars, sea urchins, sea cucumbers, sand dollars, starfish, basket stars

examples of invertebrates

shrimp, earthworm, spider, squid, cockroach, sea urchin, fly, snail

How do some invertebrates protect themselves?

some invertebrates have hard shell to protect themselves

examples of insects

spiders, bees, beetles, ants

examples of reptiles

turtles, snakes, alligators, lizards

fish

vertebrate breathes with its gills, lives in the water, temperature is same as surroundings, reproduce by laying eggs and has scales

What traits do reptiles have?

• live on land and breathe with lungs • covered with scales and live in warmer climates • reproduce by laying eggs
