Because insects have 6 legs, arachnids have 8 legs.

8 legs not 6

Answer 4

Insects have three body sections - head, abdomen and thorax and six legs.

Spiders have two body sections - head and abdomen and 8 legs.

Answer 5

Spiders are arachnids, and the most basic difference between spiders and insects is that spiders have eight legs and insects have six.

Insects also are mostly herbivores, and spiders are carnivores.

Answer 6

A spider is not an insect. It is an arachnid. Other arachnids are ticks, mites, and scorpions.

Arachnids are arthropods, animals that have legs and joints but no backbone.



Spiders have eight legs and eight eyes. They have jaws and fangs. They have spinnerets that silk comes from to spin webs.

Spiders smell and taste with their feet. They do not have a nose or tongue.

Spiders bodies have two parts.

Cephalothorax- the head and legs attached to it.

Abdomen- holds the spiders organs.

They are arthropods, more related to lobsters ( think of that the next time you go to a sea food restaurant ).

Answer 10

because they do not belong to phylum insecta, rather arachnid. They have 8 legs instead of 6 and have 2 body segments instead of 3.
