​

Answer 1

Answer:

A large majority of arthropods belong to the three main groups:

• Insects.
• Arachnids.
• Crustaceans.
• Exoskeletons made of chitin.

• Highly developed sense organs.

• Jointed limbs (the limbs must be jointed like the joints in a suit of armor, since the exoskeleton is rigid and cannot bend to allow movement).

• Segmented bodies.

• Ventral nervous system. “Ventral” means “in front,” so this means that arthropods’ nervous systems run along the front of their bodies, near their stomachs, instead of along their backs like the spinal cords of animals.

• Bilateral symmetry. This means that the left and right sides of an arthropod are the same – it will have the same number and arrangement of legs, eyes, etc. on the right side of its body as on the left.
• Insects such as ants, dragonflies, and bees.

Arachnids such as spiders and scorpions.

• Myriapods (a term which means “many feet”) such as centipedes and milipedes.

• Crustaceans such as crabs, lobsters, and shrimp.
