Manta Ray

Again, as scary and large the stingray in the photo may look, others have been caught and documented to be much larger. For example, back in 2015, a stingray weighing nearly 800 pounds became the largest freshwater fish ever caught by rod and line. The stingray came in with a measured length of 14 feet and width of 8 feet and took nearly two hours to reel in.
