1 T. 6. THE VERTEBRATES 1.- Relate the following concepts to their definition. Later, relate each concept to one of the pictures you are going to see. 1.- FIN a.- mammals with their babies 2.- GILLS b.- to eat 3.- OPERCULUM c.- not oviparous 4.- LATERAL LINE d.- degenerated 5.- LIMBS e.- organs to fly 6.- TAIL f.- submerge under water 7.- HIBERNATE g.- organ formed during pregnancy 8.- ECTOTHERM h.- layer that protects an egg 9.- SCALES I.- they are covering the body of the fishes 10.- SHELL j.- covers gills in bony fishes 11.- VENOMOUS k.- organ that secretes substances 12.- POISONOUS TEETH l.- muscles to fly 13.- CAPARACE ll.- they form the plumage of birds 14.- DIVE m.- organ to protect 15.- WINGS n.- when temperature of the body changes 16.- HOLLOW BONES ñ.- respiratory organ in aquatic animals 17.- BEAK o.- stop activity in winter 18.- FEATHERS p.- locomotion organs in fishes 19.- ATROPHIED q.- birds use it to eat 20.- FLYING MUSCLES r.- bones that are empty 21.- FEED s.- arms or legs 22.- TAKE CARE OF BABIES t.- last vertebrates 23.- GLANDS u.- teeth that are poisonous 24.- VIVIPAROUS v.- produces toxicity 25.- PLACENTA w.- sensorial organ of fishes 2.- Relate each picture to a name and classify them into a group of VERTEBRATES: ANURA CARINATAE TURTLES MONOTREMES RATITES BONY FISH MARSUPIALS URODELA SNAKES PLACENTAL MAMMALS CARTILAGINOUS FISH CROCODILES FISH AMPHIBIANS REPTILES BIRDS MAMMALS

2 3.- NAMES GAME: Classification Game of the VERTEBRATES: Each student will have a piece of paper with: - a name of a living thing in English - a name of a living thing in Spanish - a picture of a living thing - a taxonomic group that classifies living things The students will have some seconds to join each name with its picture and the taxonomic group that living thing belongs to. Later, the students will have to exchange their pieces of paper and start again. The group who finishes before the rest each time will have the positive point!!!. These are the names: LIVING THINGS GROUP GROUP ALLIGATOR BONY FISH CHAMALEON EQUIDNA TURLES FISH EAGLE

4 26.- Mammals can swim, fly, climb and run Monotremes give birth to undeveloped babies Placental mammals give birth to developed babies Marsupials are the most primitive mammals Platypus and equidna are monotremes kangaroo and koala are marsupials Dogs and horses are placental mammals. 6.- Match the words of the two columns that relate some groups to their characteristics: BONY FISH URODELA REPTILES FISH AMPHIBIANS BIRDS MONOTREMES RATITES PLACENTAL MAMMALS ANURA CARTILAGINOUS FISH TURTLES CROCODILES CARINATAE MARSUPIALS SNAKES MAMMALS 1.- They have an operculum 2.- They can jump and swim 3.- They breathe through gills 4.- They usually have 4 limbs and are ectotherms 5.- They are amphibians with tail 6.- They have wings and a beak 7.- They are falcons and penguins 8.- They can have different shapes but have a tail 9.- They have fins 10.- They are amphibians with no tail 11.- They are salamanders and newts 12.- They have no flying muscles 13.- They are ostriches 14.- They can have metamorphosis 15.- They do not have an operculum 16.- They are elongated and legless 17.- They are frogs and toads 18.- They are lizards and crocodiles 19.- They are mammals and oviparous 20.- Mammals with undeveloped babies 21.- They have a carapace 22.- They are chameleons and iguanas 23.- Their skin is covered by scales 24.- They are the biggest reptiles 25.- They lay eggs with no shell legs, viviparous and endothermic 27.- They have a placenta 7.- Classify the following pictures into the Vertebrates Groups: 8.- What is the difference between: - A bony fish and a cartilaginous fish - An anura and a urodela - A turtle and a lizard - A lizard and a snake - A lizard and a crocodile - A carinatae and a ratite - A monotreme and a marsupial

5 - A placental mammal and a marsupial 9.- Watch the following video about Vertebrates and Invertebrates and classify the following names into the different groups of animals : KOMODO DRAGON POISON DART FROG BALD EAGLE IGUANA LION BLUE SPOTTED SALAMANDER LION FISH ALLIGATOR BLUE JAY RED SPOTTED NEWT SNOWY OWL PARROT FISH AFRICAN WILD DOG SWORD FISH SNOW LEOPARD BOX JELLYFISH GIANT AFRICAN SNAIL EARTH WORM VASE SPONGE TAPE WORM SALLY LIGHT FOOT CRAB PURPLE SEA URCHIN BLACK WIDOW PIN WORM WAR JELLYFISH TUBE SPONGE VAMPIRE SQUID SUN SEA STAR FISH BIRDS REPTILES AMPHIBIANS MAMMALS SPONGES CNIDARIA WORMS ECHINODERMS MOLLUSCS ARTHROPODS 10.- Complete the following text with the listening of the Vertebrates Video and the words below. Try to do it first without listening the video. What are vertebrates? Vertebrates are with an internal made of bone. Vertebrates are the most advanced on. The traits that make all the animals in this section l are their cords, vertebrate, and notochords. SPECIAL - SKELETON - ANIMALS ORGANISMS EARTH SPINAL

6 Where do vertebrates live? Each thing lives in a habitat. A provides the, and living space that each needs. There are kinds of habitat. For, a may live in part of a sunken ship or a TOUCAN may have a nest in a tree. FISH - MANY TREE - TEMPERATURE EXAMPLE - FOOD ANIMAL - LIVING HABITAT - TOUCAN What do vertebrates eat? Vertebrates have needs. They need, and. They can survive in environments in which their needs can be met. All vertebrates depend on. Some vertebrates only plants for food, while other vertebrates eat only. However, vertebrates eat both plants and animals. The three categories are carnivores, and omnivores. SOME - EAT - ONLY HERBIVORES - WATER PLANTS- AIR ANIMALS - BASIC FOOD Why are vertebrates important to the environment? Every vertebrate belongs to a. They can be of several different group chains, which make a big. Changes in a community or in an cause in the group chains and through the webs too. You are a member of your community, the way you live your makes a big difference to other living things. MANY - CHANGES LIVE - FULL WEB ENVIRONMENT - COMMUNITY MEMBERS What are the five main vertebrate groups? First of all, there are the fish. Fish live in and are the simplest vertebrate group. The groups of fish are the jawless fish, the fish and the bony fish. Fish are cold-blooded, have, gills and a heart with two chambers. Most fish have. The second group are. Amphibians live of their life in water and part on. They are cold blooded, have moist skin, no scales and most young

7 breath with and live in the water. They into adults, which is known as, and breath with lungs. GRADUALLY - LAND - AMPHIBIANS CHANGE - PART - CARTILAGINOUS SCALES - THREE - WATER FINS GILLS - METAMORPHOSIS The third group are reptiles. Reptiles live mainly on land and they are more than fish or amphibians. Reptiles are cold blooded, have a dry scaled skin, most have two of legs with five toes on each leg, excluding. The fourth group are. Birds are vertebrates with feathers and, and they are. Birds have wings, build in which to lay hard-shelled eggs and they care for their young until they can find food and survive on their own. Finally, the group of vertebrates are mammals. Mammals are the most complex of vertebrates. They have body coverings of or fur, are warm blooded, have more complex than other vertebrates and more complex body systems. GROUP - WINGS - PAIRS BRAINS - LAST - COMPLEX - NESTS - WARM BLOODED - SNAKES BIRDS HAIR What are other types of vertebrates? Marsupials, primates, rodents, cetaceans and seals.
