What is bill law larva?

Bill law larva, also known as the larval stage of the billfish, refers to the juvenile form of certain species of billfish, such as marlins and sailfish. These larvae are characterized by their elongated bodies and distinctive features that resemble their adult counterparts but are much smaller. They primarily inhabit the open ocean and undergo various developmental stages before maturing into adult billfish. Understanding their larval stage is crucial for fisheries management and conservation efforts.
