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. 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 poster even shows the giant sea scorpion; at six feet long, this long-extinct animal is the largest arthropod to have ever lived. 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. Customers have been universally impressed with the quality, beauty and detail of these posters. Pictures do not do them justice! This is a new type of poster that we call content intensive posters. Each provides a comprehensive overview of the subject presented through extraordinary images and fact-filled text. They are designed to appeal to people who enjoy reading books, watching informative and/or educational shows on cable television and subscribing to such magazines as "National Geographic", "Smithsonian" and "Scientific American". They have great educational value and are cherished by teachers, students and professionals. All posters are printed on very heavy, high-quality paper. It is also a very hard paper that preserves tiny details. Posters are then specially coated to provide a satin finish that reduces glare and enhances their presentation. These are the same high standards used to produce expensive art prints. Artists are selected on the basis of their illustration skills and their knowledge of the subject. Many have both art and science degrees. This ensures an accurate presentation of the subject.
