Life in Extreme Environments: Antarctica   Learn about the environment of a cold desert, and animal and plant adaptations. This introduction has an excellent description of the ecosystem of this cold area.
Tree of Life Project Learn how to show relationships among your life forms. A fascinating site.

This Species Gallery is divided into birds, fish, mammals, plants, reptiles and invertebrates.  Each listed life form page contains a picture, information about the life form, and a description of how it fits into the ecology of its biome.  This is a very nice site to visit with your students!

An on line library about Biological Oceanography.  Check this page for the subjects that you are wondering about: topics include many marine life forms, their evolution, the deep sea, the seasons of the sea, food chains, etc.

Corals and Coral Reefs: Good information on Coral adaptations and reef ecology

Coral Reefs: pictures and information about plants and animals on reefs.

Special Relationships

Excellent paper explains symbiosis, mutualism, parasitism and commensalism, and give helpful examples. Read this for a clear understanding of these types of interspecies cooperation.

The Coral Realm is a wonderful Thinkquest web site that has a wealth of information about corals and coral reefs.

Ocean world: Coral Reef Symbiosis:   Explains symbiosis using the example of corals and the algae that live in them. Good pictures and a short, clear description. You can share this with your students!

Research on Symbiosis in Animals at York.  This paper describes symbiosis, especially with microbes. There is a paragraph on coral, which harbors algae, but expels them if the water temperature rises.

NOAA Line Art:   This is just a listing of jpeg files.  Click on some of them to see the pictures.  These drawings might be good for some of your experiments in changing the shapes of life forms.

The Ocean Realm: Reef Life: 
Tour a coral reef and see many pictures of the animals that live there.
Monsters of the Deep:  Take a tour to the bottom of the ocean and search for strange animals there.  Both tours are outstanding.

Fish World!  This collection of images was made for a class about fishes.  It gives you an idea of the shapes that fishes can be.  It's a real eye-opener!

Corky's Fun Fishing Pages:  There's a good collection of realistic clipart images of fishes here.!

Beautiful photographs of many different kinds of  marine invertebrates will give you some inspiration on body forms for your animals!

Babes in the Sea (Larvae of Marine Animals). This site has lovely photographs of baby marine animals.  Click on a picture and it will tell you and show you what the adult looks like.  Will you be able to guess which animals are the parents?

Evolution and Adaptation

Part of a Biology Course: a very nice page on adaptive radiation and evolution.

Pictures of groups of sea animals:  Note how members of related species resemble each other.  They have descended from the same ancestors and adapted to fit into different niches in the biome.

Evolution:  A PBS mulatimedia site provides information about this process.

Evolution and Adaptation:  This page explains the concepts clearly, and defines such important words as fitness, speciation, and natural selection.

Food Webs and Energy Pyramids

Gould Food Webs for Kids: Completion game for food webs for several ecosystems. Move the pictures to the correct squares on line.  Fun!

Oceanic Food Webs, pictures, polar ecology, antarctic ecology, estuary.  Excellent explanation: read this slowly and thoroughly and you will understand the whole concept well.

Energy Pyramids and Food Chains:  Descriptions, explanations and diagrams at a site with many teacher resources.  Check this for worksheets, games,and books that you can print out.

Living on Australian shores:  very good pages on the Australian Rocky Sea Shore include an energy pyramid, listings of animals and plants, and names and descriptions for tidal levels on the shore.  Suitable for all ages.

Generalized Energy Pyramid:   An example of a marine energy pyramid with diagrams, links, and definitions by Keith Davey.  This is good for upper elementary to adult users.
