17. A 3 Year Old When Discovered
At the time of being caught, our skinless shark was about 3 years old. While male blackmouth catsharks have an average lifespan of about 7 to 9 years, females can live as long as 9 to 13 years. So if you adapt that to human years, our fish was in her late 20s to early 30’s when she was discovered.
While scientists find it hard to believe that this catshark could live so long without having any protective skin structures or teeth, the fact is that it managed to grow up in a completely normal and healthy way, even despite lacking these typical formations! Looks like when the going gets tough – the tough get going.
