The Spanish Mackerel is a midsummer fish, disappearing in the autumn. In habit they are very much like the blue-fish, and fond of leaping from the water, living mostly at the surface.

The Pompano.

The Pompano is highly esteemed as a food fish. It is widely distributed through the warmer Atlantic. It feeds upon mollusks, crustaceans, and young fish. It is caught in nets; quantities are caught in the Gulf of Mexico.

The Bonito.

The Bonito is in habits similar to the blue-fish. It preys, as do the latter, upon menhaden and mackerel. The tail is crescent-shaped and is a great aid to it in swimming. It is capable of very swift motion, hunting in schools, which are accompanied by flocks of sea gulls and other sea birds.

The Sword-fish.

The Sword-fish derives its name from its long, sword-like snout. They are most abundant on shoals and banks near the shore. They are very pugnacious in their habits, using their sword as a weapon of offense and defense, and do not hesitate to attack sharks and whales.

The Rose-fish.

This fish on the Pacific coast is known as the Rock-Cod or Rock-fish. They are found in great abundance on the southern coast of California.

The Tree-fish.
