Excerpt from The Cultivation of Oysters in LouisianaFig. 2. Diagram to show sexual organs of the oyster. D, duct of sexual gland. Other letters as above.The valves of the shell are not symmetrical, the left one, by which the oyster is always attached to its support, is deep and spoon shaped, while the right one is nearly ¿at.The work of compressing the ligament and closing the shells is done by a large, powerful muscle (plate 1, Fig. 1, m), which runs across the body between the shells, and is fastened to their inner surface over the dark-colored spots that are always found on the inside of empty oyster shells. This muscle, and some times the muscle scar on the shell, is called the eye by the Louisiana oyster fishermen.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
