Study: great whites can live past 70

Adult white sharks, also called great whites, can live up to 70 years or more, which is far longer than previously thought, according to a new study that used radiocarbon dating to determine age estimates for white sharks in the northwest Atlantic Ocean.

Scientists said that a shark's age is typically calculated by counting alternating opaque and translucent band pairs that are deposited in their spinal column.

However, as it is unclear if these band pairs are deposited annually, scientists find it difficult to accurately estimate the age or provide estimates for the longevity of many shark species.

The new study, published on Wednesday in Plos One, addresses this concern by determining the periodicity of band-pair deposits in white sharks from the northwest Atlantic using radiocarbon dating.
