This document discusses arthropods and provides examples of different types. It outlines that arthropods have four main characteristics: jointed limbs, a segmented body, an exoskeleton, and a well-developed nervous system. There are four major classes of arthropods described: centipedes and millipedes, crustaceans, arachnids, and insects. Examples are provided for each class. Arthropods can live on land, in water, and in the air, and obtain energy through predation, scavenging, decomposition, and parasitism.

1. Arthropods
OBJECTIVE:
You will be able to list the four groups of
arthropods and give an example of each.
You will be able to explain the 4 things
arthropods have in common.

2. Arthropod Facts
All Arthropod have 4
similar characteristics:

3. a. Jointed limbs that bend.
Phylum Arthropoda –
“Jointed
Appendages”

4. b. Segmented body –
distinctive parts
(head, thorax,
cephalothorax,
abdomen)
antennae
wings
claws
pincers
Lobsters have internal gills
Segments also
include
specialized parts:
wings, antennae,
gills, pincers, and
claws

5. c.
An exoskeleton- a
hard outer
covering made of
chitin.
It protects the
animal.
Endoskeleton
Exoskeleton
*Needs to be shed as the
animal grows
*exoskeleton is replaced in
a process called
molting

6. d. a well-developed nervous system (brain) to
detect things with their senses.

7. 2. Classes of Arthropods
a. Centipedes
and
millipedes:
have many
segments

8. b. Crustaceans:
shrimps, barnacles,
crabs, and lobsters –
have gills

9. c. Arachnids –
spiders,
scorpions, mites,
ticks, daddy-
long-legs

10. d. Insects – the
largest group of
arthropods and
animals!!

11. 3. Where do they live?
Everywhere:
On Land, in freshwater, in salt water and air

12. 4. How do they get energy
(food)?
Some are predators, some are scavengers,
some are decomposers, some are
parasites!!!

14. 5. Levels of Cellular
Organization
Arthropods have cells, tissue, organs and
organ systems

15. Cool Facts:
• Arthropods have been around for about
600 million years
• Have to shed exoskeleton to grow
(molting)
• 80 % of all animal life are arthropods
