Coral Zoological Poster - Astroides calycularis/Dendrophyllia ramea

The Science:

Astroides calycularis and Dendrophyllia ramea are Stony Cup Corals, the former found in the Mediterranean and the latter also in the North Atlantic. Colonial corals formerly considered “Madrepore” Corals (which term is now restricted to a particular genus), they are mostly nocturnally active. This type of Coral consists of many Polyps, each of which sits within a hard Calyx composed of Aragonite (a crystalline form of Calcium Carbonate). Depicted are a colony of Astroides calycularis on the upper left and Dendrophyllia ramea to the right, details of the anatomical structure of the Polyp and Corallite, and the development of the larval stage drifting, swimming and settling down. 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.

The Story:

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. Each comes securely rolled and will be shipped to you in a sturdy mailing tube. These lovely botanical posters are large, colorful and impressive pieces of science decor. Add a touch of vintage classroom style to your home today!
