How to identify a Longbill Spearfish
It can be distinguished from other billfishes by its slender, lightweight body, short bill, and its dorsal fin which is highest anteriorly (higher than in marlins and lower than in the sailfish). The ventral fins are located well in front of the anal fin and in all other billfish they are located close to the anal fin. The bill of the longbill spearfish is about twice as long as its lower jaw, but still quite short by billfish standards, whereas the shortbill spearfish has a bill that is barely longer than its lower jaw. The pectoral fins of the shortbill spearfish barely reach to the curve of the lateral line; in the longbill spearfish, they extend beyond the curve. The longbill spearfish has more segments (45 to 53) in the first dorsal fin than any other Atlantic billfish, although it may appear similar to the white marlin. The dorsal fin is bright blue and has no spots. The vertical bars on the body are never as prominent as in other billfish and may show only slightly or not at all.
