Japanese Sea Lion
These now extinct animals roamed the planet up until the 1970’s. They’re a subspecies of the California sea lion, and previously inhabited the Sea of Japan. Mostly, they roamed around the areas of the Japanese Archipelago. It’s one of the saddest extinct animals on this list, as their extinction was aided by hunting during the 1900s. Since they only recently became extinct, it really shows the impact humans have on animals. Luckily, these sea lions were also pretty tame and not necessarily a threat to human safety unless it was a territory issue (Wikipedia).
