Arthropods have an external skeleton.
They are the most abundant animals on
earth, but are often misunderstood.
Spiders, millipedes and other arthropods
are often mistakenly referred to as
"insects" and "bugs." This poster brings
clarity to the confusion. Each of the
five sub-phylum is carefully explained.
Highly detailed illustrations show an
incredible 98 species, many life-size. All
are accompanied by common and
scientific name.Insects account for the
great bulk of the arthropods and this
poster includes representatives of most
orders. The Crustaceans include crabs
and lobsters, but also shrimp, krill and
even barnacles. (Yes, a butterfly and a
barnacle are related!) The poster even
shows the giant sea scorpion; this long-
extinct animal is the largest arthropod
to have ever lived. It reached a length
of six feet. This remarkable poster even
includes the prehistoric trilobites. They
were the dominant life form during the
Permian, but were totally destroyed by
the mass extinction. North American
species are shown whenever possible.
