However, the Cretaceous-aged M. comanchensis has been recently reclassified as an odontaspid shark in the genus Pseudomegachasma, and is in fact unrelated to the megamouth shark despite similar teeth morphology. [8] They are a very rare genus of shark that are mainly found in temperate and tropical waters among the Pacific, Atlantic and Indian ...
