Game Animals

Next Generation Science / Common Core Standards Addressed!

HS‐LS2‐1. Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales. [Clarification Statement: Emphasis is on quantitative analysis and comparison of the relationships among interdependent factors including boundaries, resources, climate and competition. Examples of mathematical comparisons could include graphs, charts, histograms, and population changes gathered from simulations or historical data sets.] [Assessment Boundary: Assessment does not include deriving mathematical equations to make comparisons.

New Animal

This animal is huge, it has wings and a trunk, and has six legs.

This animal also eats only plants and can live in the water as well as on land.

Give it a name. Who wants to share their name?

New Animal Now, lets say you are all

scientists and you all have discovered the same thing, how are you going to know it is the same animal?

How can the scientists share the information if they all call it by a different name?

What is scientific classification? Scientific classification

System used worldwide that uses seven stages or levels to show relationships between organisms.

Seven levels of classification

Kingdom – broadest level, it has 5 divisions

animaliaplantae, fungiprotistamonera

Levels of Classification Phylum – the next level, there

are 14 phyla in the animal kingdom.

Chordata phylum (deer, fish, snakes, etc.)

Arthropoda phylum (ticks, insects, crawfish, etc.)

Mollusca phylum (snails, oysters, clams, etc.)

Levels of Classification

Class – the third level. Within the Chordata Phylum.

Mammalia ReptiliaAves

Levels of Classification Orders – based on feeding

characteristics.Wolves, coyotes and foxes are in the

Carnivore order of the Mammalian class.

Levels of Classification Family – groups of organisms

that are further alike. Classification is often based on

anatomical features. For example – wolves and foxes

both have long noses and bushy tails.

They belong to the Canidae family.

Levels of Classification Genus – composed of very

similar groups of organisms. These groups do not naturally

breed with each other.

Levels of Classification Species – contains very similar

organisms. Organisms within the same species breed with each

other. This group can be further broken into subspecies or

breeds.

Scientific Classification System

Levels of Classification (Cont.) Common Name – How most

people know animals. Many people call animals and

various organisms by their common names. Example: Gray Wolf

Levels of Classification (Cont.) Scientific Name – Combination of

the genus and species. To ensure that scientists are talking

about the exact same animal, they use scientific names.Example: Canis lupus (Canis is the genus, and lupus is the species)

What are the differences between vertebrate and invertebrate animals?

A common way of classifying animals is based on internal and external body structures.

Morphology – study of internal and external body structures of organisms.

Animals can be classified into vertebrates and invertebrates.

Vertebrates & Invertebrates Vertebrate – animal with a

backbone. Other characteristics include:

Two pairs of appendages (legs and/or arms).

A three-segmented body (head, neck, & trunk).

Brain at one end of the spinal cord. Some vertebrates have a long tail

while others may be very short in length.

Vertebrates & Invertebrates Invertebrates – animals that

do not have a backbone. Often these animals have an

exoskeleton. This is an external hard body

covering which protects their internal organs and also their body.

What are the types of vertebrate animals?

Mammals Fishes Birds Reptiles Amphibians

Mammals Animals that are covered with fur or

hair. Regulate their internal body

temperature. Their heart has four chambers. Females produce milk for their young. Mammals can further be classified

based on their digestive system. Mono-gastric animals – have a single

compartment stomach. Ruminant animals – have a four-

compartment stomach.

Fish Fish have an exterior covering of

scales or skin. They have paired fins, and get

oxygen from water through their gills.

They adjust their body temperature to the surrounding water.

Some fish lay infertile eggs, which are later fertilized by the male.

Some others give birth to live young.

Identify these New Mexico Fish!

Birds They are covered with

feathers. They have two sets of

appendages. One set is used for flying

(wings). The other set is for walking or

swimming (legs). Birds lay fertile eggs.

Reptiles They have dry skin

covered with scales. With the exception of

snakes, reptiles have two sets of legs and five clawed toes on each leg.

Reptiles lay thick walled fertile eggs.

Amphibians Animals that live in the water

and on land. Their skin secretes mucus for

protection. They also have two sets of

appendages Reproduction occurs in the

water or very moist soil. The young go through a

metamorphosis as they mature.

What are the types of invertebrate animals?

Insects Crustaceans Mollusks Worms Arachnids

Insects Exoskeleton. Six legs. Most can fly. Lay fertile eggs. Young go through metamorphosis as

they mature.

Crustaceans Very strong exoskeleton. Exoskeleton is shed as

they grow. Four pairs of

appendages. Two pairs of antennae on

their heads.

Mollusks Small, soft bodied animals. No internal skeleton. Divided into either bivalves or

gastropods. Bivalves - have a two part shell, like a clam. Gastropods – single part shells, like a snail.

Usually found in salt water, but can also be found in fresh water and on land.

Worms Soft bodies, no legs, no antennae. Further broken down into groups of

segmented worms, flatworms, and roundworms. Segmented worms – ex. earthworms

and leeches. Flatworms – ex. flukes and

tapeworms. Roundworms – ex. nematodes and

pinworms.

Arachnids Four pairs of legs for

walking. Two pairs of legs near their

heads. Examples include spiders,

ticks, mites, and scorpions. Some varieties carry

disease and have poisonous stings.
