What are the six kingdoms of living things? 4 Characteristics of animals 1. Many celled organisms 2. Obtain their food by eating other organisms 3. Reproduce sexually 4. Move from place to place An animal that does not have a backbone is called an nvertebrate i__________. • Most animal species (95%) are invertebrates • Can you name some invertebrates? • Jellyfishes, worms, snails, crabs, spiders & insects An animal that has a backbone is ertebrate called a V__________. • Can you name some vertebrates? • Fishes, amphibians, reptiles, birds and mammals Classification of Animals • Vertebrates • Invertebrates • 35 Major Groups called a Phylum Are Sharks vertebrates? • Yes • Although they have cartilages instead of bones, they have a skeleton and a backbone Sea anemone and many circular adial animals exhibit R______ ymmetry S_______ • What are some characteristics of Radial Symmetry Animals? • Do not have distinct front or back ends • Lives in the ocean • Senses their environment in all directions The balanced arrangement of a butterfly’s body is called ymmetry ilateral B_______ S________ • What are some characteristics of Bilateral Symmetry Animals? • Larger & More complex than radial symmetry animals • Moves more quickly • Sense organ in the front Is a Sponge an animal or a plant? • Sponge is an animal • Although it cannot move around from place to place sponge take food into their bodies What do sponges eat? • Tiny organisms such as bacteria and protists • Sponge gets its oxygen from water • Network of spikes support the sponge Sponge Larva • Sponge reproduce asexually and sexually • Sponges do not have separate sexes • At any one time of the year, some sponges are producing eggs and others are producing sperms What are Cnidarians? More on Cnidarians • Unlike sponges, cnidarians have specialized tissues • Muscle like tissues for swimming • Anemones stretch out How does cnidarians obtain and digest food? • Cnidarians captures its prey by using its stinging cells to inject venom • Then the cnidarian’s tentacles pull the prey animal to its mouth • From there the food passes into a body cavity where it is digested. Jellyfish Facts • • • • They are not used to make Jelly 98% Water No Heart or Blood Most don’t have a brain (except Box Jellyfish) • Most only detect light. Some have 24 eyes (Box Jellyfish) • When stung, Vinegar (not urine) is the best treatment • Irukandji Jellyfish (size of fingernail) can kill you with a single sting. How are coral reefs made? • Built by cnidarians 1. Free swimming coral larva attaches to a solid surface ( broken shell, sunken ship) 2. The coral polyp produces a hard, stony skeleton around its soft polyp body 3. Over thousands of years, as live corals add their skeletons, the reef grows Reflection • Prompt: Write 5 facts that you learned in the video.
