Further up the river that empties out into the Grand Waterfall is a small lake. This lake is home to Takigakure's Sakana Clan. The clan is gifted with a Kekkei Genkai that blends their molecular structure with that of a fish. In short, it's a clan of "Mer-people". With being able to alter their bodies to fish form and back comes attributes and traits associated with fish. For example, they don't have to hold their breaths underwater, and their ability to handle deep sea pressure is beyond compare. In human form, they specialize in Water Style Jutsu, and in the water...well, let's just say you wouldn't want to fight one in the water. On a side note, this clan is rivaled and often challenged to contests of Suiton no Jutsu by Kirigakure's Hoshigaki Clan.
