Roy Rogers, age 13, of Wichita Kansas or his question:

Is the shark a fish?

Yes the shark is a fish and not a mammal like the whale. He is however a very primitve fish, His bones are made of cartilage and he breathes through a series of slits rather than through fishy gills, He has no sealer and his leathery hide is dotted with denticles ‑ which era really useless little teeth, In facts we are told that the shark was the first animal an earth to develop teeth and he grew them all over his body,

He seems to have been satisfied with this wonderful invention because he never went on to develope complicated proper teeth as the other animals dad. Oh, he has plenty of teeth in his mouth, his haws are filled with rows of them. But they are not deeply rooted proper permanent teeth.

The shark has a bad reputation as a killer and in many cases this is well deserved. The 40‑foot great white shark of the tropics can and will attack any living thing in the water' including man. But there are 150 different kinds of shark and not all of them are bad. One of the harnless ones is the whale shark. He may be 50 feet long and tip the scales at 20 tons ‑ which rates him the title of Biggest Fish in the Sea. Yet the whale shark feeds entirely on plankton, a seafood mixture of little algae plants and fish eggs.
