Arthropods

Front 1

What are the three main characteristics of arthropods?

Back 1

exoskeleton, segmented body, and jointed appendages

Front 2

How do arthropods move?

Back 2

jointed appendages; such as walking legs. Most appendages are modified for swimming. Many insects have wings and can fly.

Front 3

How are arthropods protected and supported?

Back 3

have an exoskeleton; muscles attach from the inside. The exoskeleton must be shed and replaced from time to time to allow for growth. called molting.

Front 4

How do arthropods reproduce?

Back 4

They reproduce sexually. have male and female organs in their body. Have internal fertilization.

Front 5

Describe the circulatory system of arthropods.

Back 5

The circulatory system is "open." Blood is pumped by a heart through open spaces in its body.

Front 6

Describe the respiratory system of arthropods.

Back 6

Gas exchange between oxygen and carbon dioxide. It occurs by way of gills or book lungs and special air tubes.

Front 7

What are the 5 major groups of arthropods?

Back 7

crustaceans, arachnids, centipedes, millipedes, and insects

Front 8

Describe crustaceans.

Back 8

has two or three body sections
three pair of appendages for chewing
5 or more pairs of legs
two large antennae
has a pair of legas attached to each body segment
breathes through gills in every type of water

Front 9

Give several examples of crustaceans

Back 9

crabs, shrimp, crayfish, lobster,barnacles

Front 10

Describe centipedes and millipedes.

Back 10

body divided into many segments, have one or two pairs of legs attached to each segment, have antennae

Front 11

Describe arachnids and their relatives.

Back 11

has only two body sections. The first section is a combined head and chest. The last section is call the abdomen. have four pairs of legs, no antennae, breathe with organs called book lungs or tiny tubes.

Front 12

Give some examples of arachnids.

Back 12

spiders, mites, ticks, scorpions

Front 13

Describe the arthropods called insects.

Back 13

many have wings, many have antennae, body is divided into three segments and have three pairs of legs.

Front 14

What are the three body regions of insects?

Back 14

head, thorax, and abdomen

Front 15

How do insects protect themselves?

Back 15

A hard exoskeleton protects them.
Many can run quicly or fly away from danger.
Some smell or taste bad to predators.
Some stings
Many use camouflage, or protective coloration in which the insect blends with its surroundings so it is nearly invisible to a predator. Some resemble different animals such as spots on wings resemble large eyes.
