A Japanese fisherman once caught a frilled shark at the surface of the water in 2007. The shark was then put on display in a marine park in Japan. Unfortunately, it died after only a few hours in captivity showing how fragile these animals are when they are not in their natural environment.

It's interesting that these animals hold the world record for the longest time it takes for an animal to give birth. Their pregnancy can last up to 42 months. The silver medalist elephant, on the other hand, only needs 18 to 22 months to have a baby. But the shark babies grow inside the mother, and they don't come out until they are ready to live on their own. This way, the younglings that are already well-developed and have a better chance of surviving after they are born.

Even though the shark is not in danger, the IUCN says that overfishing makes it harder for them to find food. Most of the time, they get caught in fishing nets, which can be dangerous for the species. Frilled shark babies take a long time to grow up, so when female frilled sharks are caught by accident, it can hurt their numbers.
