Animal Phyla

Cnidarian

Invertebrates with stining cells Ex: Jellyfish, Polyps

Mollusca

Soft body, usually enclosed in a shell; Ex: Snail, Clam

Echinodermata

Organism that has radial symetry , a spiny outside and tube feet; Ex: starfish

Annelida

Segmented and soft body Ex: Earthworms

Arthropoda

Organisms that are segmented and have a chitin exoskeleton Ex: Crabs, Lobster

Chordata

Organisms that have a true vertebrae, dorsal nerve chord and are bilateral

Innate Behavior

Behavior that is influenced by genes by genes and does not depend on learning

Learned Behavior

A behavior that has been learned by experience or observation

Verterbrate

All creatures with a backbone of vertebrae that encloses the spinal cord

Inverterbrate

Animals that do not have a backbone

Pheromones

A chemical produced by animals for communication

Parasites

An organism that feeds in another living creature, usually without killing it

Estivation

To spend hot dry summers in an inactive/dormate state

Migration

The relatively long-distance movement of individual animals, usually on a seasonal basis. It is found in all major animal groups, including birds, mammals, fish, reptiles, amphibians, insects, and crustaceans

Hibernation

To spend winter under dormate conditions ex. bears

Exoskeleton

A hard outer structure such as a shell of an insect or crustacean that provides protection

Reptile

Phlyum Chordata: Land life, Lay hard shell eggs, cold blooded

Mammal

Phlyum Chordata: Warm blooded, have hair or fur, feed milk to young, live birth

Amphibian

Phlyum Chordata: Begin life in water and can go on land, cold blooded, have soft shell eggs

Fish

Phlyum Chordata: Have scales, swim, live in water

Birds

Phlyum Chordata: have wings, have feathers, have eggs,.

Ectothermic

Lacking an internal mechanism for regulating body heat

Endothermic

Internal regulation system

asymmetrical

no symmetry

radial symmetry

The quality of having many lines of symmetry that all pass through a central point.

bilateral symmetry

Body plan in which only a single, imaginary line can divide the body into two equal halves.

exoskeleton

external skeleton; tough external covering that protects and supports the body of many invertebrates

endoskeleton

An internal skeleton

hydrostatic skeleton

A fluid skeleton in many soft-bodied invertebrates, including annelids, that allows an organism to change shape but not volume.

Cephalopoda (Mollusca)

These have a muscular foot, a shell created by a mantle, and a visceral mass to contain organs. They can also change color

EX: Nautilis, squid, octopus

Bivalvia

The class of the phylum Mollusca that includes clams, oysters, and mussels.

Gastropods

A mollusk with a single shell or no shell.

Arachnids

A member of a major arthropod group that includes spiders, scorpions, ticks, and mites. All members have eight pairs of walking legs.

Crustaceans

Any of various predominantly aquatic arthropods of the class Crustacea, including lobsters, crabs, shrimps, and barnacles, characteristically having a segmented body, a chitinous exoskeleton, and paired, jointed limbs.

Pollinator

An animal that carries pollen from one plant to another of the same species, enabling plants to reproduce.

Exothermic

Organisms cannot regulate their own body temperature; cold-blooded

hibernation

A period of inactivity that some animals experience in winter that allows them to survive on stored body fat

Platyhelminthes

A phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates EX:flatworms, tapeworms

Porifera

"pore bearing" They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them

Cooperation

Behavior by two or more individuals that leads to mutual benefit

competition

The struggle between organisms to survive in a habitat with limited resources- food, shelter, water, mating pair

social hierarchy

An order of social classes with producers at the bottom and leaders or kings at the top ex. Pecking order in chickens
