Billfish

Billfish are a type of large, fast-swimming fish known for their distinctive long, flat, spear-like bills. They belong to families such as Istiophoridae (including marlins and spearfish) and Xiphiidae (swordfish). These fish are primarily found in deep ocean waters and are highly prized by anglers and fisheries for their size and fight. Billfish play a vital role in marine ecosystems as predators, helping maintain balanced fish populations. They are also significant in commercial and recreational fishing, making conservation efforts important to protect their populations amid threats like overfishing and habitat loss.
