Happy Spooky Wednesday, everyone!

This week, Kala is sharing some of the mysteries of Lake Baikal in Siberia, Russia. This is the world’s deepest, oldest, and largest (by volume) freshwater lake!

What could possibly be hiding in its depths? It holds more flora and fauna than any other lake in the world, including the only existing freshwater seals, fish that turn into an oily substance, and… mermaids? Also, there may be a monster.

It’s definitely not a sturgeon.
