Crayfish Zoological Poster - Astacus astacus
The European or Noble Crayfish is widespread across Europe, found in freshwater rivers, streams lakes and ponds, hiding amid rocks, reeds and logs. Considered perhaps the best crayfish for eating, they are cultivated for human consumption, and are threatened in the wild due to habitat disruption, acid rain and - significantly - the introduction since the 1960’s of the Signal Crayfish from America, a carrier of Crayfish Plague which has severely weakened the population. Depicted at the top is an adult crayfish in the water, beneath that is the anatomy in cross-section including the circulation, alimentary canal and nervous system, an array of all the nineteen limbs of the left half of the body, and a detail of the underside of the female tail, half-shown with spawn. This is one of a wonderful series of Scientific German Educational Charts, created in the 1950s and 60s and still produced by the original printer, internationally recognized for producing educational science charts since 1929. These charts are issued today using the original film and same methods as the first printing. They are printed without inscription for both classroom study and decorative purposes, with special attention paid to botanical detail and scientific accuracy.
Mounted on linen canvas stretched on wooden rods for display, each measures 44.5 inches tall by 32.25 inches wide (85 cm x 120 cm), and comes with a nylon cord strung through the top wooden rod for easy hanging.
