Title: Animals!!


1
Animals!!

Classicfication
  • Vertebrates animals with a backbone
  • Fish, birds, mammals
  • Invertebrates animals without a backbone

Symmetry
  • Radial symmetry body parts are arranged in a
    circle around a center point.
  • Bilateral symmetry body parts arranged in the
    same way on both sides of its body.

  • Sometimes they have wings

18
Vertebrates Vertebrate CharacteristicsThey
have backbones. They belong to the phylum
Chordata. Chordates are A huge phylum that has
subphyla called vertebrata, tunicates and
lancelets All chordates have a notocord, which
is a flexible rod-like structure along the
dorsal side of an animal
19
They also have a Dorsal hollow nerve cord
tubular bundle of nerves that lies above the
notocord.
20
Lastly, they have gill slits paired openings
located in the throat behind the mouth.
21
What is an endoskeleton? Vertebrae (bones that
cover the dorsal nerve cord) and other bones that
are internal. Endo- means within. Supports and
protects the internal organs
22
What is an ectotherm? An animal whose internal
body temperature changes when the environment
temperature changes. Otherwise known as cold
blooded.
23
What is an endotherm? Animals that keep a
constant internal body temperature even when the
environment temperature changes.
24
FishThey are ectotherms. They have gills for
breathing. Most fish are going to have fins.
These are used for steering, balancing and
moving. Fish have scales. These are hard,
thin, overlapping plates that cover the skin and
protect the fishs body. They are made of bone.
25

26
Fish are broken up into 3 groups. These groups
are the jawless fish, the cartilaginous fish and
the bony fish. An example of a jawless fish is a
sea lamprey. They have round mouths and their
bodies are long and tubelike. They have slimy
skin and no scales. Their bodies are made of
cartilage.
27
Cartilage tough, flexible tissue that is not as
hard as bone.
28
Cartilaginous fish have skeletons made of
cartilage. Unlike the jawless fish though, these
fish have moveable jaws and they have scales that
feel like sandpaper. An example would be a
shark.
29
Bony fish have skeletons made of bone. Gills are
covered with a Hard gill cover. Some examples of
bony fish are tuna, yellow perch, and salmon.
30
AmphibiansAmphibians are ectothermic
vertebrates that lives part of this life in the
water and part of its life on land.
31
They have moist skin, which is smooth and does
not have scales. oxygen and carbon dioxide are
exchanged through the skin. They also have
sac-like lungs in their chest that they use for
breathing. Amphibians hibernate during the
winter.
32
Hibernation that period of inactivity and lower
metabolic needs during the winter.
33
They also do something called estivation during
the summer months when the weather is extremely
hot. Estivation a period of inactivity and
lower metabolic needs during the hot, dry summer
months.
34
Their skeleton is made of bones. Some examples
are frogs, toads, salamanders and newts. What
is metamorphosis? A series of changes that a
larva goes through to become an adult.Their
larva stage is spent in water and their adult
stage is on land.
35
ReptilesA reptile is ectothermic, vertebrate
with dry, scaly skin.
36
Examples of reptiles are lizards, snakes,
turtles, crocodiles and alligators. They have a
thick, waterproof skin. They also have scales
that prevent them from drying out. Most reptiles
have four legs. Which ones dont? SNAKES!
37
The four legs are have claws that help them to
hold their body off the ground which helps them
walk faster. They also use their claws to dig
and climb. Reptiles breathe with lungs. The
young develop in an amniotic egg leathery egg
that provides a complete environment for the
developing embryo.
38
Turtles found on almost every continent and most
of the worlds oceans. They are covered by a
thick, hard shell. They do not have any teeth.
They feed on insects, worms, fish, and plants.
39
Crocodiles and alligators largest reptiles.
Found in or near water. Crocs have long, slender
snouts and are very aggressive. Alligators are
less aggressive and have very broad snouts.
40
Lizards and snakes largest group of reptiles.
Lizards have movable eyelids, external ears, legs
with claws on each foot. They eat meat and
vegetables. Snakes hear vibrations not sound
waves. They smell with their tongue. They eat
meat.
41
Birds Birds are vertebrates. They are also
endotherms. Birds have feathers and scales. As
you may know they are the only animal that has
feathers. Birds also lay eggs. The eggs that
they lay though are not like reptile eggs. They
are not leathery. They have a hard shell
instead. The parents incubate their eggs.What
does it mean to incubate? Keep the eggs warm by
sitting on them.
42
Birds have four legs but their front legs are
actually wings. Their back legs support them and
they usually have claws on their toes. Birds
also do not have teeth. They have a beak
instead. If you eat eggs, you know what an egg
looks like. The eggs that they lay are also
called amniotic eggs. Birds can lay two to eight
eggs at one time.
43
Birds have two types of feathers. They are
contour feathers and down feathers. Contour
feathers strong and lightweight. Give birds
their color and their shape. Use these to fly.
They help with steering and keeps them from
tipping over.
44
Down feathers soft and fluffy. Provide
insulation in adult birds and cover the body of
baby birds. Help birds to keep their constant
temperature.
45
Something that you might not know about birds is
that their bones are hollow. This is going to
make the bird lighter making it easier for the
bird to fly. Birds generate their body heat
from their food. This is how they maintain their
body temperature.
46
MammalsMammals are endothermic vertebrate.
Have hair and produce milk to feed to their
youngMammary glands produce the milk female
mammals use to feed their young.
47
Oil glands are used to lubricate hair and skin.
Sweat glands are used to help an animal stay
cool. Animals also have scent glands which can
be used to marking territory, attracting mates
and for defense. Mammals all have hair at
sometime in their lives. Some have a lot of fur.
This fur is going to traps air to keep them
warm. Some only have little hairs. Some have
hairs that have changed over time into quills.
What kinds of animals have quills? porcupines
48
All animals have teeth. You can tell what an
animal eats by looking at its teeth. There three
ways to classify animals by the way that they
eat.Herbivores animals that only eat plants
49
Carnivore animal that only eats other
animalsOmnivore animals that eat both plants
and animals.
50
There are three different ways that animals can
be classified. They are monotremes, marsupials,
and placental mammals. Monotremes mammals that
lay eggs with tough, leathery shells.
51
Marsupials pouched mammals that give birth to
tiny, immature offspring.
52
Placental Mammals embryos develop inside the
uterus of the female. The time that it takes for
the embryo to develop is called the gestation
period. Have a placenta a sac-like organ
developed by the embryo that attaches to the
uterus. It absorbs oxygen and food from the
females blood. It does this through the
umbilical cord attaches the embryo to the
placenta.
