Which superphylum does Phylum Arthropoda belong to? Why?

Superphylum Ecdysozoa; because these animals have exoskeletons.

What is ecdysis?

The process of shedding or molting an exoskeleton

What is their exoskeleton made of?


Describe the body plan of arthropods.

Bilaterally symmetrical; segmeted bodies; well-developed eyes; highly adapted; jointed appendages

Why are arthropods so wildly successful?

They have jointed appendages

What are their joints made of?

A thinner cuticle

What kind of environment do arthropods live in?

Marine, freshwater, and terrestrial

What is special about terrestrial arthropods?

They are the most abundant in variety and numbers

How many germ layers do arthropods have? What is special about their coelom?

Three- they are triploblastic. They have a reduced coelom.

How do arthropods eat? Describe their digestive mechanism.

Some have mandibles, some have syringes. All have a complete, differentiated digestive tract.

Describe aquatic arthropods' respiratory mechanism.

Gills or book lungs

What respiratory mechanism do terrestrial arthropods use?

Arthropods do not have lungs; they have trachea.

How do arthropods respiratory mechanism work? What is a disadvantage?

Muscle movement helps move oxygen directly to the cells and carbon dioxide away from the cells through tracheal tubes.

This system limits their size.

What is hemocyanin? Where is it found?

Hemocyanin is an oxygen-carrying protein found throughout the bodies of arthropods.

Describe arthropods' nitrogen waste removal mechanism.

Arthropods have Malpighian tubules.

What is the difference between the nitrogen waste removal mechanism of terrestrial and water-dwelling arthropods?

Water-dwelling: diffuse ammonia into water.

Terrestrial: Ammonia is converted to uric acid.

Describe arthropods' nervous mechanism.

Highly coordinated sense organs:

-- compound eyes- better at seeing/sensing motion than humans

-- can taste- with sensors on legs

-- can hear- with antennae and tympanum

-- can smell

What is a tympanum?

A thinnly stretched piece of tissue and hearing structure

What do arthropods use for structural support?


What is one huge advantage arthropods have?

Jointed legs and wingss

How do arthropods maintain internal stability?

Arthropods produce nitrogen waste and decrease the amount of water lost. Also, their exoskeleton is waterproof.

How do arthropods reproduce?

Generally, they have separate sexes.

What is unique about insects?

80% of insects go through metamorphasi

most insects have wings

legs are only on the thorax

only terrestrial

3-part bodies

Name the three parts of an insect's body.

Head, thorax, abdomen

What subphylum or subphyla belong in Phylum Arthropoda? What is an example of each?

1. Subphylum Chelicerata

2. Subphylum Myriapoda

3. Subphylum Hexapoda

4. Subphylum Crustacea

What class or classes belong in Subphylum Chelicerata? What is an example of each?

1. Class Merostomata- horseshoe crabs

2. Class Arachnida- spiders, scorpions, ticks mites

Name one or more animals that belong in Subphylum Myriapoda.

Centipedes and millipedes

What class or classes belong in Subphylum Hexapoda?

Class Insecta

What order or orders belong in Class Insecta? What is an example of each?

1. Order Coleoptera- beetles

2. Order Diptera- flies, mosquitoes

3. Order Hymenoptera- wasps, bees

4. Order Lepidoptera- butterflies, moths

5. Order Isoptera- termites

6. Order Orthoptera- grasshoppers, crickets

Name one or more animals that belong in Subphylum Crustacea.

Crabs, lobsters, crayfish, shrimp
