The Arthropods

Origen:

 Is believed that the origin of arthropods comes from the annelids. 

Characteristics: 
The   body was long and soft and has many segments, all. 
Aré very similar.
 Had one a pair of  legs
Later the body sur face hardened to create an external skeleton

Tipes

There are four types of Arthropods 

Insects for example : flies,grasshoppers or wasp.

Myriapods for example: centipedes.

Aracnids for example : spiders or escolopendra

Crustaceans for example : crab ,lobster or prawns

Parts of the body 

• Wings
• Thorax
• Head
• Legs
• Abdomen

Other information

The exoskeleton of arthropods is a continuous layer called the cuticle, which extends from both ends of the gut and respiratory tract or through the cavities, and which layer is situated

THE FISH

The fish are cold-blooded

also have gills to help them breathe

and the fish hatch from eggs

there are many tipes of fises

parts of fish

             

                  -eye        -opercle           -elvic fin     -lateral line

            -mouth   -pectoral fin    -caudal fin   -dorsal fin

fish live in cold water

or other fish in hot water

the fish they forget things

in about three seconds.

Mammals

                                                                      Mammals                               
The Mammals are vertebrates

mammals are  viviparous

examples:panda,elefants,whales…

the parts of a mammal like  a panda are:

                                             

parts of a elephant:

all the mammals have hair.

the blue whale is the most bigger and heaviest mammal in the world.

we're in the group of the mammals because we have hair and the people don't born in eggs like birds,reptiles…(ect)

 the babies drink the milk that the mothers give to them in the mum's breasts.

                   I hope you liked it.

THE INSECT

THE INSECTS:

SOME  INSECTS HAVE ANTENNAS, WINGS AND  SOME INSECT HAVE A SIX FEET

THE INSECT ARE INVERTEBRATES

THERE ARE MANY TYPES OF INSECTS

EXAMPLE:THE SPIDER THE CENTIPEDE THE BEETLE  ARE ARTHOPODS

SOME INSECTS THERE ARE WINGS


EXAMPLE THE CENTIPEDE AND THE SPIDER DONT HAVE  WINGS

MY FRIENDS ROSARIO  HAVE A  PROJECT GOOD

BECAUSE  THE PROJECT IS A VERY  INTERESANT

ROSARIO EXPLAIN THE ANIMALS  ARE INSECT

SHE EXPLAIN  THE INSECT HAVE WINGS ,FEET ,ANTENNAS


THE PROJECT OF ROSARIO IS GOOD I LIKE THE PROJECT


ROSARIO  WORK GOOD

BUT ROSARIO  CAN WORK MUCH GOOD

THERE ARE MUCH INSECT IN THE WORLD

I LIKE INSECTS :BUTTERFLIES AND LADYBIRDS

I DONT LIKE  :SPIDER ,CENTIPEDES

THE AMPHIBIANS

 * The amphibians are vertebrates.

The frogs are one example of amphibians, they (like other amphibians) do a process call metamorphosis.

* They live in water or in a some city with water, because the skin of the amfibians have to be moist.

There are four main stages in the life cycle of a frog. 

               

                                       EGG

The first stage in the life cycle of the frog is the egg.

A frog lays many eggs at one tine.

The eggs are convered with a jellylike coating.

                                 TALOPOLE

The second stage of the frog life cycle is the talopolo.

hatched tadpoles have gills for breathing in the water.

they have a tail, but no legs.

As a tadpole grows ,lungs begin to form.

                                   FROGLET 

The next stage of the frog life cycle is the froglet. 

These legs help the frog on land.

                                 ADULT FROG

Once the lungs for and begin to work,the gills and tail disappear.

The adult frog is now ready to live on land.

Whath is the first stage of the frog life cicle?

The first stage of the frog life cycle is the egg.

Whath is the nest stage of the frog life cycle?

The nest stage of the frog life cycle tadpole . 

Whath is the last stage of the frog life cycle?

The last stage of the frog life cycle is the adult frog. 

BIRDS

                the birts     The birds  are vertebrate animals and oviparous animals . The birds are warm blooded  .The parts of a bird are upper mandible , lower mandible , lore ,  crow , nape , eyering ,breast  ,winds coverts , underparts , primari feathers and  tail feathers .   I put a foto of a birds . The are 10.000 different species of a different birds .  All the birt are  colorfull  .I thin that the birt are beutiful animals .How more birds eat greatly depent of the especies . Some bird live in side of trees .               

the mammals


the mammals  are warmblooded and are vertebrates .
mammals are viviparous  and about 5487 species currently known.
therre is plenty of mammals , there are small as bats and big as elephants and rhinos. we humans are mammals.
most mammals feed their Young with milk, some mammals are pests. besides sucking mammals is mainly characterized by the presence of body hair, most mammals have  brais more
developed. four example the dolphins are mammals.
are characterized by the backbone in several distinct parts dividaida.the mammals is in the group of animals smarter worl.
some mammals have four legs and two, some ae domestic mammals and other wildyourself like wild dogs and cats like tigres nd lions.
depending on how you feed the carvores hervibores ovnivoros and scavengers. carnivorous  a lion herbivores a giraf ovnivorous a humans and scavengers a whale.

ARTHROPODS

                    ARTHROPODS

·       The arthropods are in every were.

·       There are over 700,000 types of arthropods.

·       The types of arthropods are: Mirapods, insects, crustacea and arachnida.

·       The insects are butterflies, ants…There are over 1 million none types. 

·       The crutacea are crab, lobsters…There are over 44 thousand types none.

·       The arachinida are scorpions, spiders…There are over 65 thousand types none.

·       The mirapods are centipedes, millipedes…

·       The arthropods are invertebrates.

·       The arthropods are oviparous.

·       The arthropods live in water, land and some of them can fly.

·       They usually live on land.

·       You know if it’s an arthropod if it has got this things:

1º: A segmented body.

2º: Many jointed legs or limbs.

3º: An exoskeleton.

4º: Cold blood.

·       The arthropods are the most interesting animal for me because the arthropods can fly, they creep and they can crawl.

·       I like the arthropods because the butterfly is an arthropod.

·       And I don’t like the arthropods because most of them are disgusting.

AMPHIBIANS

AMPHIBIANS

·       Some of the amphibians have 4 legs and some of them have no legs.

·       All the amphibians lay eggs.

·       They lay a lot of eggs

·       All most of the amphibians have 4 legs but some of them don´t have legs.

·       They live on land or in water.

·       They have webbed feet.

·       They have cold blood.

·       They have smooth skin.

·       They don’t have hair or fur.

·       All the amphibians are born in the water with gills and a tail.

·       When they grow they have lungs and legs so they can live on land.

·       They are more than 4,000 types of amphibians.

·       They are oviparous.

·       The name amphibians means 2 lives one in water and one on land.

·       One of the types of amphibians are Anura that means that they don’t have a tail, like a frog.

·       And other type of amphibian is the Caudata that means that they have a tail, like a salamander.

·       And the last type of amphibians is the Gymnophiona that means that they don’t have legs, like a caecilians.
