1 BIO 10 FUNDAMENTALS OF BIOLOGY Instructor: K. Villatoro Student s Name: EXTRACREDIT PROJECT ANIMALS OF SOUTHERN CALIFORNIA S OCEAN WELCOME TO THE CABRILLO MARINE AQUARIUM! This site was chosen because it exhibits most of the Phyla of the Kingdom Animalia that we have been studying in class, and these animals are native to Southern California!!! The objective of this guide is: a) to expose you to some of the animals found in each Phylum and b)to develop an appreciation of the diversity of animals that Southern California has to offer. If at any point you need some help with the classification of any of the organisms, consult the on page 7 of this handout. ORIENTATION: Use the following map to orient yourself. This assignment follows each of the exhibit halls starting with the rocky shores. Be sure to identify the tank by the number. Answer the questions at each tank using what is in the tank and the information provided around it. TANK 1: LIVING IN THE SURF What Phyla are represented IN this tank (actually IN the tank, not JUST in the tank labels)? Write the common name and the Phylum the organism belongs to, like the example provided. Sea star PHYLUM Echinodermata 1

2 Now you have noticed that this tank has representatives from different phyla but they all have something in common, they are adapted to living in the same environment, the rocky shores. What is the main environmental factor of rocky shores that these organisms must adapt to in order to survive here? Each organism is adapted to this factor in a different way. For each of the organisms list the adaptation that allows them to survive in the rocky shores. See the example provided. Sea star ADAPTATION Tube feet provide movable attachment Your muscle strength is (greater or lesser) than the checkered periwinkle and (greater or lesser) than the California Mussel. TANK 2: HOUSEBUILDERS What Phylum do these Feather-dusted worms belong to? Why are they classified in this Phylum and not in the other worm-like Phyla (eg. Nematoda)? (hint: body cavity) What is the feather duster for? When you see them in the tank they don t look like worms, why? (hint: where is most of the body? TANK 3: GRAZERS and BROWSERS These organisms share the same source of food: Plants. List the phyla represented in this tank and the way each organism is able to obtain their plant food. PHYLUM OBTAIN FOOD BY Snail Mollusca Radula scrapes plant 2

3 What characteristic of the Phylum Mollusca do all the mollusks in this tank share? Do all mollusks in this tank have a shell? TANK 4: PLANTLIKE ANIMALS List the common name and the phyla to each of the organisms found in this tank Snail PHYLUM Mollusca Why do you think that people would confuse these animals with plants? Are Gorgonians considered an individual or a colony? Draw a Gorgonian coral showing each of the individual polyps Tank 6 and 7: Predatory and Non-predatory Echinoderms The organisms in this tank belong to the Phylum Echinodermata. What characteristic of the Phylum is visible in these animals? 3

4 Find each of the following echinoderms in these tanks, observe them and indicate in this table where in their body are the tube feet located TUBE FEET LOCATION Sea star Sea urchin Sea Cucumber Bristle Star What do the following echinoderms eat? FOOD Heather star Sea cucumber Purple sea urchin Bat star Describe how sea stars prey on other animals? Observe the tube feet of the sea urchin. Are all the tube feet identical to each other? TANK 12: TOUCH TANK Identify the organisms in this touch tank. You are welcome to touch but always be nice!!! PHYLUM 4

5 Express yourself!!! Draw your favorite animal of the touch tank or any other tank TANK 13 AND 14: CRUSTACEANS What Phylum do all these animals belong to? What Class do these animals belong to? Name two characteristics of the Phylum visible in these crustaceans? Count the number of joints one appendage has: What do these crustaceans eat? (hint: what is at the bottom of the tank?) TANK 17: OCTUPUS What Phylum and Class does the octopus belong to? From the diagram on the wall, what characteristic does the octopus share with other members of the Phylum? What are the chromatophores for? TANK 18: MORAY EEL What Phylum and Class do these 2 animals belong to? 1. Moray eel: 2. Red rock Shrimp: What is the relationship between the moray eel and the red rock shrimp? 5

6 TANK 25: A MUDFLAT METROPOLIS List the phyla represented in this tank. PHYLUM Compare the sole fish to the surfperch. SOLE SURFPERCH Where is the fish found? Top or bottom of tank Eye location relative to mouth Fin location relative to mouth Why do you think the sole stays mostly at the bottom of the tank? Are soles born with this unusual eye orientation? Explain TANK 28: JELLYFISH What Phylum do the Moon Jellies belong to? What part of their body do they use for stinging? Why do they sting? WHALES AND DOLPHIN EXHIBIT What Phylum and Class do whales and dolphins belong to? Why are whales and dolphins not classified as Class Osteichthyes (bony fish)? What structures in the skeleton of a whale can you see present that shows that whales don t belong in the Class Osteichthyes? Name three techniques for feeding in baleen whales How much milk does a baby whale drink per day? 6

7 CLASSIFICATION OF KINGDOM ANIMALIA Domain Eukarya: Kingdom Animalia Phylum Porifera: sponges Phylum Cnidaria: hydras, jellyfish, corals and anemones Phylum Platyhelminthes: flatworms Phylum Nematoda: roundworms Phylum Mollusca: mollusks Class Polyplacophora: chitons Class Bivalvia: clams, scallops, oysters, mussels Class Cephalopoda: squids, nautilus, octopus Class Gastropoda: snails, slugs, nudibranchs Phylum Annelida: annelids or segmented worms Class Polychaeta: clam worms, tube worms Class Oligochaeta: earthworms Class Hirudinea: leeches Phylum Arthropoda: arthropods Class Crustacea: Crayfish, crabs, shrimps, roly-poly Class Arachnida: spiders, scorpions, ticks, mites Class Chilopoda: Centipedes Class Diplopoda: Millipedes Class Insecta: flies, grasshoppers, butterflies, beetles and other insects Phylum Echinodermata: echinoderms sea stars, brittle stars, sea cucumbers Phylum Chordata: chordates Subphylum Urochordata: tunicates Subphylum Cephalochordata: lancelets Subphylum Vertebrata: vertebrates Class Agnatha: jawless fishes Class Chondrichthyes: cartilaginous fishes (sharks and rays) Class Osteichthyes: bony fishes (salmon, catfish, tuna, goldfish) Class Amphibia: amphibians (frogs, toads and salamanders) Class Reptilia: reptiles (turtles, snakes, lizards, crocodiles) Class Aves: birds Class Mammalia: mammals 7
