The megamouth shark was formally described as Megachasma pelagios in 1983.
Genetic studies confirm that the megamouth shark belongs to its own family, Megachasmidae, with no close living relatives among modern sharks. Its lineage split deeply from other lamniform sharks, leaving it evolutionarily isolated.

While most shark families contain multiple species, the megamouth stands alone as the sole surviving member of its lineage. That isolation means an entire evolutionary branch depends on a single living species.
If lost, Megachasmidae would disappear completely, erasing tens of millions of years of independent evolutionary history and narrowing the genetic diversity of Earth’s largest predatory fish.
