1 Animals PresentationThis is an overview of the major Animal groups. It includes some major vocabulary.You will be assigned one group to research further and do a project on.
2 Concept Map Assignment On a piece of paper create a concept map of at least 15 bubbles that includes information in this presentation. Animals should be the center or top of your concept map.For Example:AnimalsAre sorted into two main groupsVertebrateInvertebrate
3 Two main groups of animals Invertebrates- Animals without backbones/spinesMost are smaller because they do not have a backbone.Exoskeletons- tough outer coverings that do not grow but offer protection.Exoskeletons have to fall off in order for the organisms to grow…molt.Vertebrates- Animals with bones and spines5% of animal species are vertebratesAll have muscles, a digestive system, a respiratory system, a circulatory system and a nervous system with sensory organs.Endoskeleton- internal support system such as a skeleton made of bone tissue
4 Animal Body Plans and Symmetry All animals have complex, specialized Body Plans.Organ Systems, Organs, Tissues that all do specific jobs.An Animals’ Body Symmetry will tell you a lot about its body plan and systems.Symmetry is the arrangement of the animal’s body parts.Radial symmetryBilateral symmetryAsymmetrical
5 Radial symmetryBody parts are arranged in a circle around a central point.Example: The spokes on a wheel.
6 Bilateral SymmetryBody parts are arranged in the same way on both sides of its body.Each ½ is a mirror image of the other.Example: A Butterfly
8 Asymmetrical Some organisms have no definite shape There is no way their bodies can be divided into matching halves.Example: There are many articles of clothing that are asymmetrical.
9 Six types of invertebrates: Porifera = SpongesCnidariansEchinodermsMollusksArthropodsWorms
10 Porifera = SpongesSimplest invertebrate animal on Earth. They live in water and filter food from their environment.
11 CnidariansLive in water and have a central opening. Most have stinging cells for protection or catching prey. Examples: Jellyfish, sea anemones, hydra, corals
12 WormsInvertebrate animals that live in water or on land. They have soft, tube shaped bodies that have a distinctive head.
13 MollusksInvertebrate animals that are divided into 3 groups. These animals have strong muscular feet in order to move and capture food. Ex: Clam, Snail, Octopus
14 EchinodermsInvertebrates with a spiny outer skeleton and central openings to take in food. Ex: Sea urchin, Sea cucumber, Star fish, Sand Dollar
15 ArthropodsInvertebrate animal with a segmented body and exoskeleton. **See All About Arthropods** Ex: Insects crabs millipedes, arachnids.
16 Five groups of vertebrates: BirdsReptilesMammalsAmphibiansFish
17 Body Temperatures in Vertebrates Ectotherm- animals whose body temperatures change with the environmentEx. Fish, Reptiles, AmphibiansEndotherm- animals that can maintain a constant body temperature.Ex. Birds, Mammals
18 Reptiles Scaly skin to protect from dry, harsh climate Ectotherm Young look like little adultsOften active at nightLay hard-shelled eggs, fertilized internally
19 Amphibians Slimy, wet bodies Ectotherms Live some part of life cycle in waterYoung usually do MetamorphosisLay soft-shelled eggs, fertilized externally
20 Birds Birds live in most environments Most can fly -> special adaptations to flyEndotherms- have adaptations for staying warmHave feathers and a beak; 4 limbs: a pair of scaly legs and a pair of wingsLay hard-shelled eggs
22 Characteristics of Mammals Diverse groupAll mammals have hair (during some part of their life cycle) and body fat.Have teeth specialized for consuming particular kinds of food.All mammals produce milk to feed their youngGive live birth (a couple odd ball exceptions)
23 Fish Most diverse group of vertebrates Adapted to life in all aquatic environments.Fish Reproduce Sexually
24 Fish are adapted to living in the water: swim bladder controls depth at which the fish swimsStreamlined- muscles & fins push the fish through the watergills remove oxygen from water and in exchange for releasing carbon dioxidelateral line- which is an organ that allows fish to sense objects or organisms near by.
25 20, 000 different kinds of fish Kind of fishTraitsExamplesJawlessTube-like shape, no stomach in their digestive systems.Lampreys, hagfishCartilaginousSkeletons made of cartilage, feed on small animalsSharks, rays, skatesBonyBodies covered in scales, Skeletons made of boneTuna, flounder, goldfish, perch, eels, (most fish you think of)
