Cybiosarda elegans

 ( Scombridae ) 

The leaping bonito ( Cybiosarda elegans) is a species of saltwater finfish from the Scombridae (Scombridae) family. Scombridae includes such tribes as the , , and – of the latter of which, the Bonito tribe, this fish is a member. It is the only member of the genus Cybiosarda, which is therefore called a monotypic taxon.

Since the bonitos and tunas are close relatives, this fish has variously been referred to by such other common names as Australian tuna, striped bonito and Watson's bonito.

Description The leaping bonito, like other Scombridae, has an elongated body with a deeply forked tail, and Finlet. Like other tunas, it lacks a swim bladder.

The dorsal fin is very high, and the anterior of it is black. The back displays a spotted pattern with lots of dark, oval-like spots, with a deep blue undertone. The sides display striped marks which fade as they closer to the belly, similar to the related skipjack tuna ( Katsuwonus pelamis) and black skipjack ( Euthynnus lineatus). The second Dorsal fin and Fish fin are yellow.

It can reach in length and in weight.

Distribution and ecology It is found in coastal and oceanic waters of northern Australia and southern New Guinea.

Like other tunas, it will travel in large schools to hunt down smaller fish, and may be found closer to shore following Forage fish in winter months.Dianne J. Bray & Sascha Schultz, Cybiosarda elegans /ref>
