Early arthropods—worm-like
The story of bugs begins with the story of
creatures with thick skin like
arthropods. Arthropods are the most successful an outer skeleton—move

skeletons, legs with joints, and segmented bodies.
The first arthropods developed on Earth more

Most arthropods are small. Some, like
this sea scorpion, grow big and are
the first predators, or animals that
attack and eat other animals.
Trilobite
Tiny trilobites were common

two feelers (antennae) and a
body split in three sections,

HEARING
Bugs have super senses to help
them survive. They share the same
senses as humans—sight, smell,
touch, taste, and hearing. These
are used to find food, escape from
predators, and meet mates. Like
