THE INVERTEBRATES WEB QUEST BY MRS. INOUE QCC Standards Fifth Grade- LA Strand: Communication LA5.59, LA5.64; Science Strand: Inquiry S5.2; Strand: Life Science S5.18 Introduction Task Resources Process ... Conclusion INTRODUCTION: How many different kinds of animals do you think there are in the world? If you said over a million you are right! There are about 1.3 million species of animals on Earth today and probably millions more that are unknown. It's not an easy job of keeping track of them either. You've been introduced to the classification system scientist use when you did the Classification Scavenger Hunt located on this site. You learned that animals are classified into two large groups-vertebrates (have backbones) and invertebrates (have no backbone). Invertebrates account for about 95% of all those animals! (Most of you hypothesized that the Vertebrate group had more.) As you can see there has to be a method of maintaining order when it comes to identifying and classifying this many creatures. TASK: Invertebrates are classified into eight phyla (phyllum is singular) that include: Sponges, Cnidarians (coelenterates), Flatworms, Roundworms, Segmented Worms, Mollusks, Echinoderms, and the largest group called the Arthropods. The class will be divided into five groups to use the resources listed here to develop a cluster map that will include the kinds of animals, characteristics, habitats, food, body symmetry and special features, and five interesting facts about the phyllum.

Examine how animals are classified according to these categories. Then, list the seven categories that are used to classify animals. Finally, classify a human, a red abalone, and a bald eagle, according to the seven categories. You may find the above Web pages more helpful for classifying kingdom and phylum; however, the following Web pages will provide more specific classification information. List each category and write the name of each organism's specific classification.

Lecture Summary Who are the animals? Animal Phyla: A review of the Kingdom Animalia. Animal Diversity. Who are the animals? Animal Phyla: Porifera, Platyhelminths, Cnidarians, Ctenophores, Nematoda, Nemertea, Rotifera, Mollusca, Annelida, Arthropoda, Echinodermata, Chorodata. What separates these animals from other organisms? Some properties of animals. Of 1.5 million know species of living things, about a third are animals. (to summary) A review of the Kingdom Animalia. The Sponges-Phylum Porifera: These live in water, mostly in the sea. Some sponges have no symmetry, but those that do are radially symmetrical. They have no nerves or muscles, and their embryonic development is atypical. Flagellated, collared cells called choanocytes create a current of water, the collar filters small particles from the water; the Amoebocyte digest and distribute these particles. The CnidariansJellyfish, Anemones, Corals. Another largely marine group. There are two Cnidarian body plans: the medusa and the polyp. Some cnidarians are exclusively one or the other; and some are have both forms in their life cycle. Both body plans are radially symmetrical. A diagnostic feature of cnidaria is the cnidocyte or "stinging cell."

72. AnimalPhylogeny1 However, the locomotion of worms typically involves rather simple propagated wavesof information in this paper is primarily from cnidarians and sponges. http://www.cco.caltech.edu/~brokawc/Bi11/AnimalPhylogeny1.html

Lets return to the problem of trying to understand the evolutionary origin of the Metazoa . We have looked at a variety of organisms below this level; now lets consider a top-down approach, and propose that: The first "real animals" were worms. What distinguishes worms from other animals? The lack of a rigid (usually jointed) skeleton. What is a skeleton? Muscles can only contract. They do not actively elongate. An external, antagonistic force is needed to stretch them out again. This antagonistic force is usually conducted by a skeleton. The primary function of a skeleton is to provide for muscle antagonism , usually between different muscles that can be independently controlled, but sometimes between muscle and elastic antagonists. Soft-bodied animals must have solved this problem, without a rigid skeleton. But worms share the following characteristics with other "real animals": Use muscles for locomotion, by creating "waves" of muscle contraction. I want to focus on locomotion, and the fact that there is an enormous gap between the use of actin and myosin for locomotion by an amoeboid cell like Naegleria , and the use of actin and myosin in muscle cells of worms and other multicellular animals.

Chapter 6 Study Guide Part I 1. Describe the physical characteristics of sponges that give them their unique ability to absorb and hold water. The surface of a sponge is perforated by may tiny pores that allow water and nutrients to flow into the central part of the sponge where the water may be trapped in tiny pores from which the nutrients can then be extracted. 2. Describe the type of feeding behavior sponges engage in and what their typical food supply consists of. Sponges are filter feeders that rely on their own ciliated movement of water through the system of passages in their structure. Food particles are typically planktonic algae which are filtered from the water within the passages of the sponge structure. 3. Describe the two basic forms that Cnidarians can take. What features do these two forms share in common? In what way are these two forms different? Cnidarians can take either a polyp or medusa form. The two forms are both radially symmetrical and have a group of tentacles arranged around a central mouth located on the oral surface. The oral surface on a polyp faces up toward the open water, while the oral surface on a medusa form of cnidarian faces down on the bottom side of the "bell." 4. Describe the tissue composition of Cnidarians.

Discuss with the person sitting to your left a characteristic of each and an example that would fit into that phyla. I will do the first one for you: mollusk - soft-bodied animal - squid. Today we are going to experience a learning adventure that will introduce you to different characteristics of invertebrates. Your text defines invertebrates as an “animal that has a skeletal system inside its body.” Let’s brainstorm as many animals that fit this definition and list them on the chalkboard.
