The Bonito are actually eight different species from four genera (three of which have one species each). It is in the family Scombridae which also includes tuna and mackerel.
Such fish are traditionally caught in the Maldive islands, where they are a staple of the local diet. Processed (cured) fish that is ready for eating or export (to Sri Lanka, for example) are called "Maldive fish."
This scalloped coin was minted in 1984 and 1990 only. It was replaced with a smaller round version in 2012.
