How Animals are Classified

Key Concepts

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 ConceptsKey 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 VocabularyKey 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.

• Genus - A group of living things that includes separate species.

VocabularyVocabulary

• 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.

• 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.

VertebratesKey ConceptsVertebrates

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.

• 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 ConceptsKey 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.

vertebrate skeletons. • Vertebra - one of the bones or blocks of

cartilage that make up a backbone.

• 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.

VocabularyVocabulary

• Cold-blooded - having a body temperature that changes with temperature of surroundings.

• Warm-blooded - having a body temperature that stays the same.

InvertebratesKey ConceptsInvertebratesKey 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 ConceptsKey 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.
