You know how alot of mythical creatures like the unicorn and the dragon, along with ancient creatures like the megladon are considered to for mythics never had existed and ancients to have gone extinct. Well I believe that alot of them it's possible for them to have existed and to still exist today. Here's my short list of the ones that still exist today; unicorns, dragons, fairies, nymphs, megladon, Loc Ness Monster (Nessie), and more.
