2. The Animal Kingdom Characteristics of Animals • They are multicellular. • They reproduce either sexually or asexually. • They have distinct body parts that do different things. • They can move around. • They cannot make their own food.

4. Animal Kingdom • Animals are classified into the Animal Kingdom. • Animals are consumers. • Animals can be grouped as • Invertebrates or vertebrates.

5. Invertebrate -No backbone Vertebrates - Backbone present

6. Vertebrates can be further characterized as endotherms or ectotherms. • Endotherms-Animal that can produce its own heat and can maintain a constant body temperature. • Ectotherms-an organism that needs sources of heat outside of itself. (cold blooded)

8. Animal Kingdom:Answers Invertebrates Vertebrates

9. Invertebrates • Invertebrates are by far the most numerous animals on Earth. • Nearly 2 million species have been identified to date. These 2 million species make up about 98 percent of all the animals identified in the entire animal kingdom. • The true number of invertebrate species may be as high as 100 million and that the work of identifying and classifying invertebrate life has only just begun.

11. symmetry • Most animals have symmetry. Let’s look at the different type of symmetry. • Asymmetry • Radial • Bilateral

12. Bilateral- Two halves of an organism’s body are mirror images of each other.

14. Radial symmetry- in which the parts of the body are arranged in a circle around a central point.

16. Asymmetry-When you cannot draw straight line to divide its body into two or more equal parts. Its body is not organized around the center.

20. To breathe or not to breathe Animals have different ways to breathe. We will the two ways that animals breathe: • Gills • Lungs

21. Animals have different methods of locomotion and respiration. • Gills-breathing organ of fish:the organ that fish and some other water animals use to breathe, consisting of a membrane containing many blood vessels through which oxygen passes.

23. Lung-respiratory organ in vertebrates that transfer oxygen into the blood and remove carbon dioxide from it.

26. Let’s move Animal have different body parts that allows them to move. Let’s learn about some of those ways. • Tube feet • Tentacles • Appendages

27. Tube feet- radial canals connected to dozens of tiny suckers; used for feeding, moving around, or performing other functions depending on the species.

28. Starfish - ampullae and tube feet

29. Tentacles-  a long flexible organ around the mouth or on the head of some animals, especially invertebrates such as squid, used in holding, grasping, feeling, or moving

31. Appendage- a body part or organ that projects from the main part of the body, e.g. a tail, wing, or fin.

32. 1+1=3 • Some animals reproduce asexually, but most reproduce sexually. We will learn the different types of each. • Budding • Fragmentation • Conjugation • Internal fertilization • External fertilization

33. Some animals reproduce asexually, but most sexually. • Budding-a form of asexual reproduction in which an outgrowth of the parent pinches of and eventually separates to form a new individual.

35. Fragmentation- parts of organism break off and then develop into a new individual that is identical to the original one.

37. Conjugation-the simplest form of reproduction, in which two single-celled organisms such as bacteria or protozoans link together, exchange genetic information, and then separate.

39. Internal fertilization- When the eggs of a female is fertilized inside of the female.

41. External fertilization- When the eggs of the female is fertilized outside of the female body.

42. Simple Invertebrates • Sponges- are invertebrates animals that have no body symmetry and never have body tissues or organs. They are filter feeders that are able to reproduce both sexually (external fertilization) and asexually (budding). Sponges belong to the phylum Porifera. Adult sponges are not able to move.

44. Cnidarians are a phylum of invertebrate animals that have stinging cells and take food into a central body cavity. The stinging cells allow them to capture food and defend themselves. Cnidarians exhibit radial symmetry. Many adult cnidarians can move to escape danger and capture food. They are able to reproduce sexually, utilizing external fertilization, as well as asexually, mostly through budding. Examples of cnidarians include coral and sea anemones.

46. Worms are invertebrates that have long, narrow bodies without legs. They exhibit bilateral symmetry. They have tissues, organs, and organ systems. Worms reproduce both sexually and asexually.

47. Worms are divided into three groups-flatworms (phylum Platyhelminthes) , roundworms (phylum Nematoda) and segmented worms (phylum Annelida).
