How Animals are Classified
Key Concepts
• “Biologists classify organisms based on
similarities such as appearance, cell
structure, hereditary material, and
means of getting food and reproducing.
• The seven levels of classification are
kingdom, phylum, class, order, family,
genus, and species.
Key Concepts
• Each level of classification groups
organisms that are more similar to each
other.
• The scientific name of an organism is its
genus then its species such as: Tyto alba.
(barn owl)
Key Vocabulary
• Classify - group things based on the
features they share.
• Phylum - subdivision of a kingdom
(plural is phyla).
• Genus - A group of living things that
includes separate species.
Vocabulary
• Species - a group of organisms that can
breed with each other to produce
offspring like themselves.
• Scientific name - the name given to each
species, consisting of its genus and its
species.
Vertebrates
Key Concepts
• All vertebrates have an internal skeleton
made of bone or cartilage, a backbone,
and a skull.
• A shark is unlike most fish because its
skeleton is made of cartilage and most
fish have skeletons made of bone.
Key Concepts
• Many animals go through a
metamorphosis; A frog starts out as a
tadpole, which grows legs, loses its gills
and tail, and develops into an adult frog.
Key Concepts
• Mammals have two features other
vertebrates do not have; mammals have
mammary glands to feed their young and
mammals have hair to hold in body heat.
Key Vocabulayr
• Vertebrate - An animal with a backbone.
• Cartilage - a soft material found in
vertebrate skeletons.
• Vertebra - one of the bones or blocks of
cartilage that make up a backbone.
Vocabulary
• Swim bladder - A gas-filled organ that allows a
bony fish to move up and down in water.
• Amphibian - a vertebrate that lives at first in
water and then on land .
• Metamorphosis - a major change in form that
occurs as some animals develop into adults. An
example would be a frog.
• reptile - an egg-laying vertebrate that breathes
with lungs.
Vocabulary
• Cold-blooded - having a body
temperature that changes with
temperature of surroundings.
• Warm-blooded - having a body
temperature that stays the same.
• Mammary gland - a milk-producing
structure on the chest or abdomen of a
mammal.
Invertebrates
Key Concepts
• Invertebrates have many methods of
feeding for instance a sponge strains its
food particles out of the water that moves
through their bodies.
• Body plans are different in invertebrates;
radial symmetry is like spokes on a wheel
and bilateral symmetry is a body plan
that has identical right and left sides.
Key Concepts
• There are three main types of worms;
flatworms (tapeworms), roundworms
(hookworms), and segmented worms
(leeches, earthworms).
• Many invertebrates molt as they grow,
for example, arthropod's external
skeleton does not grow, so they must shed
(molt) their skeleton to grow in size.
Key Concepts
• Invertebrates have many different ways
of movement, for example, Echinoderms
attach their tube feet to surfaces and pull
themselves along.
Key Vocabulary
• Invertebrate - an animal that does not
have a backbone.
• Cnidarian - an invertebrate animal that
includes jellyfish, corals, and hydras.
• Radial symmetry - an arrangement of
body parts that resembles the
arrangement of spokes on a wheel.
Vocabulary
• Tentacle - an arm like body part in
invertebrates that is used for capturing
prey.
• Flatworm - a simple worm that is flat and
thin.
• Bilateral symmetry - a body plan that
consists of left and right halves that are
the same.
Vocabulary
• Roundworm - a worm with a smooth,
round body and pointed ends.
• Segmented worm - a worm whose body is
divided into sections, such as earthworms
or leeches.
• Mollusk - an invertebrate divided into
three parts.
Vocabulary
• Arthropod - a member of the largest
group of invertebrates, which includes
insects.
• Molting - the process by which an
arthropod sheds its external skeleton.
• Crustacean - a class of arthropods that
includes crabs, lobsters, crayfish, and
sow bugs.
Vocabulary
• Arachnid - a class of arthropods that includes
spiders, scorpions, mites, and ticks.
• Complete metamorphosis - changes in form
during development in which earlier stages do
not look like the adult, example is a butterfly.
• Incomplete metamorphosis - changes in form
during development in which earlier stages
look like the adult.
Vocabulary
• Pupa - a stage in the development of some
insects that leads to the adult stage.
• Tube foot - a small structure used by
echinoderms for movement.”
