Here’s a new mystery fish photograph just received. Anyone have any ideas what it is?

Although it is not a cryptid, it certainly is an unknown until identified. These photos are making the Internet rounds as evidence of a new world record piranha, an extremely dubious identification.

Meanwhile, the Cryptomundo mystery fish photograph on an antique postcard (first noted at Cryptomundo on November 29, 2005, contributed by phyllis) has still not been solved.
