Do sea turtles live as long as Crush in Finding Nemo?

Yes. Scientists have not been able to determine the lifespan of sea turtles, since they tend to outlive humans, and therefore any research projects. Also, tagging and monitoring is a fairly new technology, so consistent, reliable data has not yet become available. Nonetheless, sea turtles as believed to live for up to a century, and quite possibly longer. Unfortunately, many sea turtles involved in research are likely to die from a variety of threats such as being entangled in fishing line or nets, being illegally poached for their meat and shells, and from pollution and ingesting rubbish.
