Elephant Shark
Both New Zealand and Australia are known for its exotic and peculiar creatures, so it comes as no surprise that one of the oldest shark species can be found there. Elephant Sharks use their distinctive snouts to get to shellfish hidden in the sand, that’s basically how they hunt. According to the Nature magazine, they are the slowest-evolving out of all known shark species. Also known as the Australian Ghost Shark, these creatures are about 420 million years old.
