Measurement bars at the bottom show 3 meters and 9 feet for reference. — megalodon Megalodon (*Carcharocles megalodon*) was a species of shark that lived during the Miocene and Pliocene epochs (23.03 million to 2.58 million years ago).

The exact body shape of the megalodon remains a subject of scientific debate, as the species is primarily known from its fossilized teeth and vertebrae rather than a complete skeleton.1

Because of similarities in tooth structure, many researchers have historically suggested that the megalodon likely resembled the modern great white shark, appearing as a bulky, torpedo-shaped fish with a conical snout, large fins, and a crescent-shaped tail.1

However, some scientists propose that the megalodon may have possessed a sleeker, more slender body shape, potentially closer to that of a lemon shark. Proponents of this view argue that a more streamlined form would have allowed for more efficient movement through the water compared to the bulkier proportions associated with the great white shark model. Due to the lack of a complete fossil record, both interpretations remain theoretical.1
