Fascinating and unexpected aspects of deep-sea creatures that distinguish them as extraordinary on our planet.
The megamouth shark, scientifically known as Megachasma pelagios, is an exceptionally rare shark inhabiting the depths of the ocean.
Between its discovery in 1976 and 2012, a mere 54 sightings or captures of the megamouth shark were documented globally, with only three of these encounters being captured on film.
Similar to whale sharks or basking sharks, megamouth sharks feed on floating organisms and jellyfish by filtering them through the comb-like structures in their mouths. They maintain an open-mouthed swimming posture to efficiently capture their food.
Distinguished by its remarkably large head and mouth, as well as its elastic lips, this species possesses notable characteristics.
Due to numerous distinctions, megamouth sharks are categorized within a distinct family called Megachasmidae, although there is debate among experts suggesting they could potentially belong to the same family as basking sharks, Cetorhinidae.
The megamouth shark boasts a distinctive appearance, featuring a dark brown dorsal side and a white ventral side, along with an asymmetrical tail. Its upper lobe is notably large, comparable in size to the tail of a thresher shark. This unique appearance was observed in a megamouth shark discovered off the coast of Japan.
The megamouth shark is renowned for its considerable size, reaching lengths of up to 5.5 meters. Typically, males measure around 4 meters, while females can grow up to 5 meters in length, weighing up to 1,215 kilograms.
True to its name, the megamouth shark possesses a mouth of remarkable proportions, measuring up to 1 meter in width. It is equipped with numerous small teeth along with a broad and rounded snout, often leading to confusion with young orcas.
The animal’s mouth is adorned with a bioluminescent organ capable of emitting light in the dark. This luminous feature serves to attract floating creatures as well as small fish towards the megamouth shark.
Megamouth sharks are viviparous, meaning the young sharks develop in eggs inside the mother’s womb and hatch internally.
Until 2012, only 54 individual megamouth sharks had been documented.
