On average, spearfish are the smallest of the billfish family. The maximum size of a spearfish differs between each subspecies. Longbill spearfish tend to grow between 2.4 and 3 m (8 and 10 ft) in length and weigh up to 45.4 kg (100 lb). Shortbill spearfish are smaller, reaching a maximum of 2.1 m (7 ft) in length and typically weighing in between 18.1 and 31.8 kg (40 and 70 lb). Mediterranean spearfish grow to be about the same size as shortbills, with the largest Mediterranean spearfish ever caught weighing almost 31.8 kg (70 lb) and about 2.1 m (7 ft) long. The roundscale spearfish has a similar size to both the shortbill and Mediterranean, with the biggest one ever caught being 24.9 (55 lb) and just over 2.1 m (7 ft) in length.
