Inchworms
radial symmetry
Count the legs and divide by 4 then add 2 (1 for the head and 1 for the terminal posterior segment). The number is variable because they add segments as they grow. The name implies that the animal has a "thousand legs" but, that is based on hyperbole.
Animals with segmented bodies include lobsters, centipedes, and many different worms and insects. A main advantage of the segments is that the animal can use less energy when moving because they only have to move a few segments at a time.
The body of a spider has two segments, thus making it an arachnid not an insect. Insects have 3 segments.
No. Spiders and centipedes are both arthropods but neither have 3 segments.
Inchworms
When the circular muscles of an earthworm contract, the segments of its body become thinner and longer, causing the earthworm to elongate and appear stretched out.
Because Its body structure has segments.
arthropods
When you flex your arm your biceps contract, and your triceps extend. And when you unflex your arm the triceps contract and you biceps extend. The muscles work together to allow you to move your body.
They contract and extend their body; try looking at an earthworm move around.
Arachnids have two body segments, the abdomen and......

Arthropods are invertabrates (no backbone) which have segmented bodies and limbs. However, some arthropods, such as insects, have 3 body segments. Chelicerata - a group which includes spiders - have 2 segments, the cephalothorax and the abdomen.
They have two body segments and four leg segments.
