How does the bill of the White Marlin differ structurally from the Atlantic Blue Marlin's bill?
Answer
The White Marlin’s bill is generally shorter and stouter.
Distinguishing the White Marlin from other large billfish, especially the Blue Marlin (*Makaira* species), relies heavily on proportional metrics, where the bill is key. The bill, or rostrum, of the White Marlin (*Kajikia albida*) is consistently described as being shorter and possessing a somewhat stouter build when directly compared to the bill of the Atlantic Blue Marlin. This dimensional difference is considered a critical diagnostic feature that anglers and biologists utilize for accurate field identification, aiding in correct documentation of catch statistics.
