The mystery of how a shark got on a subway train may have been solved.
According to published reports, the dead dogfish shark that a NY1 viewer saw on the N train was first found by three children who saw it lying in the sand in Coney Island.
A man then reportedly took the shark off the beach and onto the subway, where he left it.
Pictures of the shark then made the rounds of social media.
MTA officials say crews disposed of it.
