Deep sea fish species found in the north Pacific Ocean have mysteriously been caught in the southwest Atlantic, on the other side of the world.
It is unclear how the animals, a giant rattail grenadier, pelagic eelpout and deep sea squid, travelled so far.
Their discovery 15,000km from their usual home raises the possibility that deep sea currents can transport animals from one polar region to another.
