Characteristics of Animals 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.

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

Invertebrate -No backbone Vertebrates - Backbone present

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)

Animal Kingdom:Answers Invertebrates Vertebrates

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.

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

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

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

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.

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

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.

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

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

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

Starfish - ampullae and tube feet

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

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

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

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.

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

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.

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

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

Animals may go through a variety of developmental stages. Complete metamorphosis-a change that involves the four stages of egg, larva, pupa, and adult in insects such as butterflies, beetles, flies, and bees

Incomplete metamorphosis- -a change that involves the three stages: egg, nymph and adult.

Larvae-the wingless immature worm-shaped form of many insects that develops into a pupa or chrysalis before becoming an adult insect

Screwworm Fly Larvae

Embryo-animal in initial developmental stage: the developing young of an animal from the earliest stages after conception up to birth or hatching.

Human mouse

Nymph-the larva of some insects such as mayflies, dragonflies, and grasshoppers that resembles the adult and develops into the adult insect directly, without passing through an intermediate pupa stage.

Pupa-developing insect inside cocoon: an insect at the stage between a larva and an adult in complete metamorphosis, during which the insect is in a cocoon or case, stops feeding, and undergoes internal changes.

The stage after a series of developmental changes. Adult The stage after a series of developmental changes.
