15 Fin-tastic Facts About The Atlantic Bonito For Kids

Read these interesting Atlantic bonito facts to learn more about this species of fish that lives in brackish waters.

The Atlantic bonito (Sarda sarda) is a large mackerel-like fish in the Scombridae tribe. Its range includes shallow coastal and offshore water in South America, the Atlantic Ocean, Mediterranean Sea, and the Black Sea, where it is considered to be a valuable commercial and game fish. It is found at the bottom of the ocean. It has a fully-scaled body, and it is one such species that has its dorsal fin separated by a narrow interspace. They are mainly silver in color and have a bluish-green dorsal fin, and are known for their dark stripes extending from their back. They are caught as catch near the coast. They are found in exceptionally large numbers in the oceanic waters of the Atlantic.

This species can be found all over the Atlantic Ocean's length and width. However, the Gulf of Mexico is their most popular destination, with the Mediterranean Sea and the Black Sea appearing occasionally. Bonito is Sarda sarda, squaring them back to the Mediterranean island of Sardinia, anchoring them in the Scombridae family of other tunas and mackerel. They bear perfect racing stripes broken intermittently by brushes of wide shadows over some magically iridescent skin.

Euthynnus alletteratus, popularly known as bonita, is a member of the Scombridae family. It is not the same as a bonito. The false albacore is toothless and unfit to consume. Solid lines extend from head to tail on the top part of the Atlantic bonito, as well as teeth. The false albacore has broken or squiggly lines, spots below the lateral line, and no teeth.

These characteristics aid in both the detection of prey and the avoidance of predators.
