This 14ft monster was caught in a Thai river after an extensive search by a biologist looking to study them. They have a 15inch arrow-shaped barb on their tail that can penetrate thru bone. They feed on clams and shrimp by detecting their electrical signature with special sensors and bury themselves in the mud as a defense.

The biologist who studied them claims that these creatures may be the largest freshwater fish in the world.

There are unverified accounts of individuals growing well over 1,000 pounds (450 kilograms) in weight and more than 20 feet (6 meters) in length

Surpisingly, they exist in a rivers in heavily-populated areas and aren’t on the local menu because they are extremely hard to catch. The one caught in the picture gave birth shortly after being captured and was released without harm.
