. A first book of zoology [microform]. Zoology; Zoologie. THE nitOOK TROUT 8Q cavity-contains tho vincora. Of thoso organs ono can readily recoKnizo the partly coilo I tubular alimentary canal extending,' from the mouth to the vent. The wider anterior portion is the stomach, on each s'de of which is the reddish- brown liver, witii a jrreen Rall-bladdcr closely associated. Following on the stomach is the inteHtine—much narrower and bent upon itself-from which pass off a number of tubular outjrrowths clustered together. Probablv in these outgrowths, as well as in the stomach and liver," fluids are manufactured; the substance produced in the liver—called (el JwmI ^ taU fin vmtnUfin FlO. 53.—Ilerringr dissected so as to show internal structure. (x j). bile-is stored up in the gall-bladder. When poured into the alimentary canal the fluids dissolve, or digest, the food. Another prominent orf,'an in the body-cavity is the reproductive organ, consisting either of two spermaries— the "soft roe"-of a male fish, or of two ovaries-the "hard roe"—of a female, containing a great many little eggs. Still nearer the back-bone, and having a rather thick, black wall, there is a long sac-like structure containing a mixture of gases; this-the so-called swim-bladder— increases the buoyancy of a fish, exactly in the same way.
