Now we know that fish with scales AND fins are equipped with a digestive system that prevents the absorption of poisons and toxins into their flesh from the waters they call home. Flounder, cod, haddock, and salmon are a few examples of fish with scales and fins. Catfish have fins, but do not have scales. These scavengers are primarily bottom feeders and have digestive systems designed to absorb toxins from the water. Clams, lobster, shrimp, crabs, mussels and squid do not have scales or fins and are believed to be highly toxic. They naturally absorb all the toxins in the water they live in.
Scales serve to protect the body from the outside dangers such as predators and infection. Cosmoid scales Cosmoid scales are found in the Lungfish (family Ceratodidae) and some fossil fishes. Cosmoid scales are similar to placoid scales and likely evolved from the fusion of placoid scales.They consist of two basal layers of bone, a layer of dentinelayer of dentine--like cosmine, and an outer like cosmine, and an outer layer of vitrodentine.
