Shortbill Spearfish (Tetrapturus angustirostris) Fish Description

Shortbill Spearfish is known under names such as the Short-nosed Spearfish, Slender spearfish and Japanese spearfish. 

They have a dark, black band across the upper part of the fish, and have a silverish-white color below it. Both its dorsal and ventral fins are close to stark black, but its anal fins are white in color. The inner surfaces of the pectoral fins and the tail are black but their outer surfaces are whitish.

To be able to distinguish the Shortbill spearfish from other relative species is by their lightweight and lean bodies. As with their names, they have the shortest bill amongst the other billfish and that their dorsal fins are >50% their bodies’ height, which is higher than a Marlin fish’s dorsal fin and lower than a Sailfish. 

In the comparison of the Shortbill spearfish to the Longbill, is that the Longbill spearfish has a bill twice the length of its lower jaw, whereas the Shortbill spearfish bill is scarcely longer than its own lower jaw. And common for all variations of the spearfish is that their dorsal is bright blue with no spots. 

 

Diet and Size

Shortbill Spearfish, such as the other spearfishes are considered to be surface feeders. And they primarily consume other small to medium-sized fish and squid.

Shortbill Spearfish can grow up to the lengths of 91 in., but most that are caught do not exceed the length of 75 in. Their maximum weight is recorded to be up to 115 lbs.
