16 classes
according to recent classification of animal taxa).
What are the main classes of Arthropoda?

What are 4 reasons why arthropods are so successful?
- exoskeleton. rigid as armor but allows flexible movement.
- segmented body and appendages. allow specialized central, organs, and locomotion.
- wings.
- small size.
- development.
- escape.
- reproduction strategies.
- short generation time.
What are the 4 main characteristics of arthropods?
- A segmented body (Figure below) with a head, a thorax, and abdomen segments.
- Appendages on at least one segment. …
- A nervous system.
- A hard exoskeleton made of chitin, which gives them physical protection and resistance to drying out.
What are the 9 characteristics of arthropods?

- They possess an open circulatory system.
What are the five characteristics of arthropods?
- Exoskeleton. Arthropods are invertebrates, which means their bodies do not have internal bones for support. …
- Segmented Bodies. Arthropods have bodies that are internally and externally segmented. …
- Jointed Appendages. …
- Bilateral Symmetry. …
- Open Circulatory System.
What do arthropods look like?
Arthropods range in length from about 1 millimeter to 4 meters (about 13 feet). They have
a segmented body with a hard exoskeleton
. They also have jointed appendages. The body segments are the head, thorax, and abdomen (see Figure below).
What is the correct order of arthropod groups?
C insects → arachnids → myriapods →
crustaceans
. D myriapods → crustaceans → arachnids → insects.
What do all arthropods have in common?
All arthropods posses
an exoskeleton, bi-lateral symmetry, jointed appendages, segmented bodies, and specialized appendages
. The major arthropod classes can be separated by comparing their number of body regions, legs, and antennae.
What are the 7 classes of arthropods?
- Onychophora (claw bearing) e.g. Peripatus.
- Crustacea (Crusta – shell) e.g. Prawn, crab, wood louse.
- Arachnida (Arachne – spider) e.g. Scorpion, spider, tick, mite.
- Chilopoda (Chilo – lip; poda – appendage) e.g. Centipedes.
Why are arthropods important?
Arthropods play an important
role in maintaining the health of ecosystems
, provide livelihoods and nutrition to human communities, and are important indicators of environmental change. … Arthropods constitute a dominant group with 1.2 million species influencing earth's biodiversity.
