The Introduction To Animals

Front 1

Mollusks

Back 1

Have soft bodies; most have a thick muscular foot for movement or to open and close their shells.

Front 2

Mollusks

Back 2

They have more developed body systems than sponges or worms. They take in oxygen through gills or lungs, and some have shells.

Front 3

Mollusks

Back 3

Examples may be slugs, snails, clams, and octopuses

Front 4

Invertebrate

Back 4

Theses animals in the Animal Kingdom include sponges, segmented worms, echinoderms, mollusks, and arthropods.

Front 5

Amphibians

Back 5

The major groups are frogs, toads, and salamanders.

Front 6

Frogs and salamanders

Back 6

have smooth, moist skin, through which they can breathe and live part of their life in water and part on land. Amphibians

Front 7

Toads

Back 7

have thicker, bumpy skin and live on land. Amphibians

Front 8

radial symmerty

Back 8

body parts arranged in a circle like a wheel

Front 9

Invertebrates

Back 9

Theses animals in the Animal Kingdom include sponges, segmented worms, echinoderms, mollusks, and arthropods.

Front 10

Reptiles

Back 10

Are cold-blooded (ectothermic); breathe with lungs; most lay eggs, although in some the eggs hatch inside the female; and have scales or plates.

Front 11

Birds

Back 11

Are warm-blooded (endothermic); breathe with lungs; lay eggs; have feathers; and have a beak, two wings, and two feet.

Front 12

Mammals

Back 12

Are warm-blooded (endothermic); breathe with lungs;

Front 13

Most have babies that are born live; have fur or hair; and produce milk to feed their young.

Back 13

Mammals

Front 14

Sponges

Back 14

Very simple animals that have many pores (holes) through which water flows.

Front 15

Examples of segmented worms

Back 15

may be earthworms and leeches.

Front 16

Echinoderms

Back 16

Have arms that extend from the middle body outwards. They have tube feet that take in oxygen from the water and spines

Front 17

Warm-blooded

Back 17

(endothermic)

Front 18

Cold-blooded

Back 18

(ectothermic)

Front 19

Warm-blooded (endothermic)

Back 19

Animals, including birds and mammals, which maintain a nearly constant internal temperature and do not change with the temperature of the environment.

Front 20

Cold-blooded (ectothermic)

Back 20

Animals, including fish, amphibians, and reptiles, which have an internal body temperature that changes with the temperature of the environment.

Front 21

Endothermic

Back 21

When the outside temperature is too hot, this animal can cool off by sweating, panting, changing position, or changing location. Sweating and panting generate heat loss through evaporating water. Changing position and location allow the animal to find a cooler environment in the shade or shelter.

Front 22

Ectothermic

Back 22

If the environment is cold, this animals become slow moving and sluggish. Some animals must bask in the Sun (for example snakes or lizards) or move to a warmer area (for example some fish) before they can move about to hunt for food.

Front 23

Arthropods

Back 23

Have jointed legs, segmented bodies, and some have wings.

Front 24

Arthropods

Back 24

They have hard outer coverings called exoskeletons. They obtain oxygen from the air through gills or air tubes.

Front 25

Arthropods

Back 25

Examples may be insects, arachnids, and crustaceans.

Front 26

Mimicry

Back 26

When a weaker animal copies stronger animals' characteristics to warn off predators.

Front 27

Mimicry

Back 27

Some animals may look like another more poisonous or dangerous animal that give it protection, such as a “false” coral snake or hawk moth caterpillar that looks like a snake. Certain moths have markings that look like eyes and some flower flies resemble black and yellow wasps that have a powerful sting and use this disguise to ward off predators.

Front 28

Hibernation

Back 28

is a state of greatly reduced body activity, used to conserve food stored in the body.

Front 29

Endothermic

Back 29

animals must eat much more often than ectothermic animals since it takes energy to maintain a constant body temperature. For example, a lion must eat its weight in food every seven to ten days.

Front 30

Echinoderms

Back 30

Have arms that extend from the middle body outwards. They have tube feet that take in oxygen from the water and spines.

Front 31

Εechinoderms

Back 31

Examples may be sea stars, brittle stars, sea cucumbers, or sea urchins.

Front 32

Sessile

Back 32

remain attached to one place for life span

Front 33

Sponges reproduce

Back 33

asexual and sexual reproduction

Front 34

Pores

Back 34

The body of a sponge is cover with many of these

Front 35

Vertebrates

Back 35

comprise only one phylum of animals. They include fish, amphibians, reptiles, birds, and mammals.

Front 36

Spicules

Back 36

The bodies of many sponges contain sharp structures

Front 37

Spongin

Back 37

help move water through a sponge

Front 38

Cnidarians

Back 38

most of these animals live in oceans

Front 39

Tapeworm

Back 39

lack digestive systems

Front 40

Round worms

Back 40

disease in dogs by heart worms

Front 41

Schistosomiasis

Back 41

a human disease caused by blood flukes

Front 42

Flatworms and roundworms

Back 42

Have bilateral symmetry

Front 43

Vertebrates

Back 43

comprise only one phylum of animals. They include fish, amphibians, reptiles, birds, and mammals.
