Extractions: By Hugh R. Williams Of the more than one million described species of animals in the world, approximately 95% fall under the heading of invertebrates. There are more anatomical differences between jellyfish and insects than there are between insects and elephants. The invertebrates comprise an extremely diverse assemblage of animals, from single celled protozoans to insects, crustaceans and starfish. There are more than thirty major groups, or phyla, of invertebrates. For our purposes here, we will discuss the general characteristics of just a few groups common along our coast and at Gray's Reef. A companion Gray's Reef poster to this section entitled "Invertebrates of the Reef," can be obtained from Gray's Reef National Marine Sanctuary, 10 Ocean Science Circle, Savannah, GA 31411. SPONGES Sponges belong to the phylum Porifera, which means "pore bearer," and constitute the simplest of multicellular animals. They are sessile organisms, which means that they live attached to objects, and therefore are not able to move about. They have no true tissues or organs, rather various individual cells perform the life functions of the sponge. Most sponges are marine; only 150 or so freshwater species have been identified out of some 5,000 species within the group. Structurally, sponges are supported by a matrix of fibrous material and interwoven spicules (tiny spikes), usually made of calcium or silica. This matrix is what remains behind when sponges are found on the beach or prepared and sold for market. The living part of the sponge exists within this matrix. Water enters the sponge through many pores, and is helped along by specialized cells which sweep the water through interior chambers and canals. The water circulating through the sponge supplies oxygen and food, and removes wastes as well. Sponges pump a surprising amount of water in a day. For example one type of sponge that measures 5 inches by 1/2 inch (10cm. x 1cm.) will pump as much as six gallons (22.5L) of water per day through its chambers.

You will learn all about the Periodic Table and its elements before you leave Jackson Creek. Below are a few of the topics we will cover in science class. Some of the topics will be covered a little more in depth than others. Each main topic is a different textbook. 7th Grade: A. From Bacteria to Plants B. Animals C. Cells and Heredity D.

Extractions: Shuffle Invertebrates - Overview Marine Invertebrates Freshwater Invertebrates An invertebrate is any multicellular animal lacking a backbone. This includes all animal phyla other than Chordata. The major invertebrate phyla include: Invertebrates are tremendously diverse, ranging from microscopic wormlike mezozoans to huge animals such as the giant squid. Approximately 95% of all the earthâs animal species are invertebrates; of these the vast majority are insects and other arthropods. Invertebrates are important as parasites and are essential elements of all ecological communities. Porifera - Sponges Porifera is an animal phylum consisting of the organisms commonly called sponges. It is the only phylum of the animal subkingdom Parazoa and represents the least evolutionarily advanced group of the animal kingdom. All adult sponges are sessile (nonmotile), and nearly all are marine; there are four families of freshwater sponges.

Extractions: Animals of the Intertidal Zones [This can accompany the text on pages 166-186 in the National Audubon Society: Field Guide to the Pacific Northwest ] First off, a brief introduction to the Linnaean Classification System used by taxonomists. This naming system is defined as hierarchical and binomial: hierarchical as it consists of smaller and more inclusive taxa as one narrows down the classification of a species, and binomial because of the official biological name that is derived for each species from the Linnaean System. The scientific name for a species is a combination of the organism's Genus and species written in a very specific and some say nerdy format. The Genus name is capitalized and italicized (or underlined), and the species name is lower-case and also italicized (or underlined). If the two names are underlined, they are underlined individually and not with one continuous underline. For instance, humans are all scientifically: Homo sapiens or Homo sapiens And the Ochre (or Purple) Sea Star is scientifically: Pisaster ochraceous or Pisaster ochraceous Why use confusing scientific names at all? (No, scientists are not arrogant and pretentious!) Scientific names are constant world-wide; while common names often differ from country to country or in some cases even region to region. For instance, one person's Rock Dove is another person's Pigeon, but Columba livia is the same to both people.
