Fish
Among fish, a true cloaca is present only in elasmobranchs (sharks and rays) and lobe-finned fishes. In lampreys and in some ray-finned fishes, part of the cloaca remains in the adult to receive the urinary and reproductive ducts, although the anus always opens separately. In chimaeras and most teleosts, however, all three openings are entirely separate.

Famous quotes containing the word fish:
“Here’s a fish hangs in the net like a poor man’s right in the law; ‘twill hardly come out.”
—William Shakespeare (1564–1616)
“Memory is a net; one finds it full of fish when he takes it from the brook; but a dozen miles of water have run through it without sticking.”
—Oliver Wendell Holmes, Sr. (1809–1894)
“When the weather is bad as it was yesterday, everybody, almost everybody, feels cross and gloomy. Our thin linen tents—about like a fish seine, the deep mud, the irregular mails, the never to-be-seen paymasters, and “the rest of mankind,” are growled about in “old-soldier” style. But a fine day like today has turned out brightens and cheers us all. We people in camp are merely big children, wayward and changeable.”
—Rutherford Birchard Hayes (1822–1893)
