Theleaping bonito (Cybiosarda elegans) is a species of saltwaterfinfish from theScombridae (Mackerel) family. Scombridae includes suchtribes as themackerels,tunas, andbonitos – of the latter of which, theSardini tribe, this fish is a member. It is the only member of the genusCybiosarda, which is therefore called amonotypic taxon.[2]
Since the bonitos and tunas are close relatives, this fish has variously been referred to by such other common names asAustralian tuna,striped bonito andWatson's bonito.[3]
The leaping bonito, like otherscombridaes, has an elongated body with a deeply forked tail, andfinlets. Like other tunas, it lacks aswim bladder.
The dorsal fin is very high, and theanterior 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 relatedskipjack tuna (Katsuwonus pelamis) andblack skipjack (Euthynnus lineatus). The seconddorsal andanal fin are yellow.
It can reach 45 cm (18 in) in length and 2 kg (4.4 lb) in weight.[2]
It is found in coastal and oceanic waters of northernAustralia and southernNew Guinea.
Like other tunas, it will travel in largeschools to hunt down smaller fish, and may be found closer to shore followingbaitfish in winter months.[4]
