Why is the spider not considered an insect
Why a spider is not an insect
welcome to moomoomath and science and
why spiders are not insects spiders are
a fascinating group of arthropods take a
look at a couple insects are also
arthropods and make up the largest group
however spiders are not insects let's
look at why
first insects are arthropods that have
an exoskeleton or a hard shell like
covering on the outside of its body
insects have three main body parts a
head thorax and abdomen insects have a
pair of antennae on top of their heads
insects have three pairs of legs six
totals and they can use these legs for
walking but sometimes an insect may have
a pair of legs that are specifically
designed for jumping many insects have
two pairs of wings that allow them to
fly spiders on the other hand also have
an exoskeleton
however spiders just have two body
regions Assefa thorax and an abdomen the
abdomen is soft in unsegmented while the
cephalothorax is hard and includes a set
of eight legs or four pairs most spiders
have eight eyes compared to most insects
who have two eyes although some insects
have three or four eyes spiders do not
have wings or antenna like many insects
many spiders produce silk for webs and
most have external digestion with
digestion enzymes acting outside of the
body to liquefy the prey all spiders are
predators while many insects eat only
plants if you'd like to know more about
