Kingdom Animalia
Today s Class Go over viewfinder lab A closer look at the Animal Kingdom Taxonomy Worksheet
Viewfinder Kingdom: Animalia Cells: multicellular Food: eats other organisms Movement: moves on own Reproduction: sexual
Viewfinder Kingdom: Plantae Cells: multicellular Food: makes own food (photosynthesis) Movement: internal movement Reproduction: sexual or asexual
Viewfinder Kingdom: Fungi Cells: multicellular Food: feed on organic matter (decomposition) Movement: internal movement Reproduction: sexual and asexual (by spores)
Viewfinder Kingdom: Protista Cells: single cell (with nucleus) Food: can make own food (photosynthesis) or eat other organisms Movement: move on own Reproduction: sexual and asexual
Viewfinder Kingdom: Bacteria (Monera) Cells: single cell (no nucleus) Food: some make their own food (photosynthesis) others absorb food from their environment Movement: move on own Reproduction: sexual and asexual
Viewfinder Kingdom: Archaea Cells: single cell (no nucleus) Food: eat inorganic substances Movement: moves on own Reproduction: asexual
Yay, Animals!
Invertebrates Animals that do not have an internal skeleton Some don t have any kind of skeleton Some have an exoskeleton (e.g. insects) A hard outer shell
1. Sponges Animals with bodies full of pores and channels that allow water to flow through them They filter-feed Example: sea sponge
Sponges
2. Worms Animals with long tube-like bodies (without bones) and no limbs Examples: flatworms, roundworms
Worms
Mollusks Can take on a number of different forms All mollusks have a mantle that is used for breathing and excretion Examples: snails, sea slugs, octopus, clams
Mollusks
Cnidarians Invertebrates that are characterised by having cnidocytes (explosive harpoon-like cell) Examples: jellyfish, sea anemone, corals
Cnidarians
Echinoderms Only live in marine environments Radially symmetrical (usually in multiples of 5-points) Examples: starfish, sand dollars, sea urchins
Echinoderms
Arthropods Have an exoskeleton made of chitin and segmented legs Examples: spiders, insects, crustaceans
Arthropods
Vertebrates Animals that have an internal skeleton
Vertebrates Some vertebrates are warm-blooded This means that they can control their body temperature internally Ex: mammals, birds
Vertebrates Some vertebrates are cold-blooded This means that they cannot control their body temperature internally They depend on the temperature of the environment Ex: reptiles, amphibians
1. Fish They have smooth or scaly skin Live in the water (have gills to breathe) Most are cold-blooded, some sharks are partially warm-blooded Examples: sharks, eels, seahorse, goldfish
Fish
2. Birds They lay eggs (oviparous) They have feathers They are exclusively terrestrial Warm-blooded Examples: cardinal, stork, penguin
Birds
3. Amphibians They lay eggs (oviparous) They have smooth skin (except toads) They are both aquatic and terrestrial Cold-blooded Examples: frogs, toads, newts
Amphibians
4. Reptiles They lay eggs (oviparous) or produce eggs that hatch in the female s body (ovoviviparous) They have scales or a shell They can be aquatic or terrestrial Cold-blooded Examples: turtles, crocodiles, iguanas
Reptiles
5. Mammals Most give birth to well-developed young (viviparous) except platypus and echidna They have fur Can be terrestrial or aquatic Warm-blooded Examples: platypus, koala, whales, tiger
Mammals
Taxonomic Tree
You need to know how to interpret a taxonomic tree!
Are birds in the same class as amphibians? No!
Are insects and crustaceans part of the same phylum? Yes!
Are crocodiles more closely related to frogs than to snakes? No!
Are sharks and rays part of class Agnatha? No!
Are birds, sharks and snakes all part of the same phylum? Yes!
