12 The Feed the Octopus Game Introduction: Mollusks are invertebrates classified in the Phylum Mollusca. This is one of the largest and most diverse phyla in the animal kingdom. In this phylum we find creatures such as snails, slugs, clams, oysters, nudibranches, chitons, squids, octopuses, cuttlefishes, and the chambered Nautilus. Mollusks are defined as soft-bodied animals that have an internal or external shell. The body plan of almost all mollusks consists of four basic parts: foot, mantle (that secretes shell), shell, and visceral mass.

13 Many mollusks such as snails and slugs feed with a tongueshaped rasping structure called a radula. Some mollusks are filter feeders while many carnivorous mollusks such as octopuses and some sea slugs use sharp jaws. Some octopuses are even poisonous. Movement is usually rather slow even somewhat sedentary; however, octopuses, squids, cuttlefishes, and even scallops, to some extent, can move quickly through the water by using a form of jet propulsion. Respiration is by gills (marine species). Land mollusks breathe by using a specially folded mantle lined with many blood vessels. Moisture is still needed in order for oxygen to enter the cells. Most mollusks have separate sexes and reproduce externally, however; there are some species that reproduce internally.

14 Phylum: Mollusca Classification Class Polyplacopora chitons Class Scaphopoda tusk shells, tooth shells Class Gastropoda snails, periwinkles, conches, whelks, oyster drills, cowries, nudibranches, limpets, abalones, slugs Class Bivalvia clams, oysters, scallops, mussels, cockles, shipworms Class Cephalopoda squids, octopuses, cuttlefishes, nautiluses

15 Feed the Octopus Our Octopus Friend is Hungry. Please Feed him! Materials (needed for each group): A pair of dice Animal food pieces Did You Know? Fact Cards Feed the Octopus Game Sheet Scissors (to cut out food pieces) Coloring supplies (if students will decorate their own game board and game pieces)

16 Procedures Divide the class into groups or four (also can be used in small group centers). Each student in the group chooses an animal food piece. Each student places his/her animal food piece on their Start square found on the Feed the Octopus game sheet. Students take turns throwing dice until one rolls any combination of eight. If more than one student rolls an eight (the number of legs on an octopus) on their first try, have those students keep rolling until the tie is broken. This student goes first. Students roll the dice trying to make a combination of eight. Each time a student rolls eight, he/she will read a Did You Know? fact card about mollusks out loud then place the card at the bottom of the stack. Then he/she will move his/her food piece one space towards the octopus. Students will only read a card and move their game piece when an eight is rolled. Dice are passed to the next player. The first student to reach the Finish box will feed the octopus by placing their animal food piece on the octopus. Continue until all students feed our hungry friend.

20 Feed the Octopus! Game Procedures Our octopus friend is hungry. Please feed him! Materials (needed for each group): - A pair of dice - Animal food pieces - Did You Know? Fact Cards - Feed the Octopus Game Sheet - Scissors (to cut out food pieces) - Coloring supplies (if students will decorate their own game board and game pieces) Procedures: 1. Divide the class into groups or four (also can be used in small group centers). 2. Each student in the group chooses an animal food piece. 3. Each student places his/her animal food piece on their Start square found on the Feed the Octopus game sheet. 4. Students take turns throwing dice until one rolls any combination of eight.

22 Food Pieces Cut these menu items out along the dashed line. Only four are needed for each group.

24 The largest octopus is the North Pacific Octopus that may grow to over 30 ft. and weigh more than 100 lbs. The smallest octopus is the Californian Octopus that only reaches 3/8 to 1 inch in length. A tusk shell has no heart. Many snails have a horny plate that seals the opening when the snail s body is drawn into the shell. Snails and other gastropods have a muscular foot that is used for movement in most species. Gastropods are the largest group of mollusks. Chitons have a single heart, a pair of kidneys, a simple nervous system, and sense organs including eyes. Have you ever eaten abalone sandwich? Haha! Most bivalves reproduce externally; however, fresh water clams fertilize internally. Bivalve shells are closed by welldeveloped adductor muscles.

26 Fresh water clam larvae attach to fish gills, where they remain as parasites until they drop to the bottom to become sedentary adults. Scallops can move rapidly by clapping their valves together. Mollusk shells have also been used as a form of currency in some preindustrial societies. The dominant features of mollusks are shell, foot, mantle, and visceral mass. Snails and clams have open circulatory systems while fast moving octopuses and squids have closed circulatory systems. Tusk or tooth shells are in class Scaphopoda. Snails and slugs are in class Gastropoda. To name a few: clams, mussels, scallops, and oysters are in class Bivalvia. Chitons are in class Polyplacophora. The Southern European garden snail s genus name is Helix.

28 Over 50,000 living mollusk species have been named. The giant squid, the largest invertebrate, can grow to a length of 60 ft. There are approximately 100,000 species of mollusks. Some mollusks don't have a shell. Some mollusks don't have a head. The name mollusk means "soft", because mollusks don't have any skeletons. An octopus is a large mollusk. Female oysters can produce as many as 500 million eggs in a year. Pearls are formed by mollusks when an irritant, like a grain of sand, becomes trapped inside the mollusk The kraken, a mythological Norse sea monster, is based on an octopus.

30 The Pygmy Octopus lays about 150 large eggs. The most dangerous predator to the octopus is the Moray Eel. Squids have an internal shell called a pen. Snails have a single shell, which spirals outward and to one side as it grows. Octopuses, squids, cuttlefish, and the chambered Nautilus belong to the class Cephalopoda which means head foot. Octopuses do not have shells. Octopuses are carnivorous. They eat fish, clams, lobsters, and other invertebrates Most female octopuses will not eat after laying their eggs. They guard the eggs instead. Most of them die from starvation after their eggs hatch. The genus name of the American land snail is Polygyra. True pearl producing oysters live in the waters of the Indo Pacific.

32 Tusk shells have a single shell that grows in a narrow and very slightly curved cone shape. Oysters, clams, and mussels have two parts to their shell that opens and closes like a hinge. Chitons are like little armored tanks with a row of eight overlapping plates protecting them. The Common Octopus found on the west coast of Florida reaches an average size of inches. The Pygmy Octopus found on the west coast of Florida reaches a maximum size of 4 inches. Octopuses have the most complex brain of the invertebrates. Octopuses have both short-term and long-term memory. Octopuses, when threatened, can release a cloud of purple-black ink. This ink is toxic, even to the octopus releasing it, so it must quickly move away to escape. Octopuses can change colors. This coloration reflects mood; white for fear or red for anger. Typically they are brown. Many octopuses produce venomous secretions. The tiny Blue Ringed Octopus found in Australia is deadly to man.
