Arthropod Basics
This word means “jointed legs,” a defining feature of all arthropods.
jointed appendages
Insects belong to this class and have six legs.

true
Crabs, lobsters, and shrimp are all types of this arthropod.
crustaceans

animal
Spiders and scorpions belong to this class.
Arachnida
Crustaceans breathe through these feathery structures.
gills
This adaptation helps arthropods prevent water loss on land.
waxy exoskeleton
Crustaceans often have two pairs of these sensory appendages on their head
antennae
This hard outer covering protects arthropods and supports their bodies.
exoskeleton
Crabs and lobsters are members of this mostly aquatic class.
Crustacea
This exoskeleton part often forms a hard shield over the cephalothorax.
carapace
This arthropod ability allows them to regrow lost limbs over time.
regeneration
This tiny crustacean is often the base of marine food chains
krill
Arthropods must shed their exoskeleton in a process called this.
molting
This arthropod class typically has two body sections and eight legs.
Arachnida
These appendages are used for swimming in shrimp and some crabs.
swimmerets
Some marine arthropods can communicate by producing these sounds with their claws or body.
stridulation
