The record setter in the image above was recently caught on reel in a freshwater river in Thailand. Giant freshwater rays occur in Southeast Asia and Northern Australia and it is unclear whether or not this species can venture into saltwater for extended periods of time. The mammoth specimen was 6.6 feet across by almost 7 feet long and it was captured and released as part of a NatGeo program covering megafishes.
