Megalodon, a massive ancient shark, had a cartilaginous skeleton, making its exact size difficult to determine. Most size estimates are based on well-preserved teeth and some vertebrae fossils. Understanding its size and biology helps scientists infer its role in prehistoric marine ecosystems and its impact on the evolution of other marine species, especially whales.
