Genesis and Giant Megalodon Longevity

The largest shark in the world today is the whale shark, an endangered resident of tropical waters that grows around 17 meters (55.7 feet). Be amazed but not afraid because it eats plankton. Something that might have kept people cautious when swimming was Otodus megalodon.

New information on megalodon has been issued where it could have grown up to 24.3 meters (80 feet), and it apparently was a predator that would eat lots of things, including other predators. It could have lived for hundreds of years, so it did not reach maturity any time soon.

Biblical creationists are interested in growth calculations for the megalodon because of how humans and organisms lived for extended periods until after the Genesis Flood. More data are needed to be certain of calculations, but it is also reasonable to compare their size (and therefore age) to the Greenland shark for reference.
Fossil remains of the giant shark Otodus megalodon have been found in Miocene and Pliocene rock layers, which ICR scientists interpret as having been formed during the Genesis Flood. Paleontologists recently revised the estimated adult body length for megalodon upward from 15.9 meters (52 feet) to 24.3 meters (80 feet). Based on considerations of swimming efficiency, they concluded the megalodon’s body was probably more elongated like that of a lemon shark (see figure) rather than stocky and bulky like that of a great white. This megalodon took a long time to skeletally mature, and delayed maturation is often associated with greater longevity in living animals.
