Can sharks live for 500 years?

What animal can live up to 500 years?
Greenland Shark
Greenland sharks live for between 300 and 500 years and are the longest-living vertebrate. They take life very slowly, moving at an average of 0.76 mph. They grow about a cm every year, and females may not reach sexual maturity until they are 100 to 150 years old – that’s one long childhood!

They are even among the very first genera given a scientific name. By far the most common fossil, based on the number of times it occurs in collections, is the snail Turritella, which is not only found almost everywhere since the Cretaceous, but is often quite abundant within each collection.

What is the most oldest thing in the world?
The zircon crystals from Australia’s Jack Hills are believed to be the oldest thing ever discovered on Earth. Researchers have dated the crystals to about 4.375 billion years ago, just 165 million years after the Earth formed. The zircons provide insight into what the early conditions on Earth were like.
Why is shark meat toxic?
Shark meat is incredibly dangerous because sharks are apex predators who accumulate high levels of toxic chemicals and heavy metals from both skin absorption and from consuming their prey. These dangerous chemicals and metals add up over time and quickly reach toxic levels. This process is known as bioaccumulation.
