Northernmost record of a whale shark Rhincodon typus from the Sea of Okhotsk.

The whale shark Rhincodon typus is the world's largest fish and it occurs in tropical, subtropical and warm temperate waters. Here, the northernmost record of R. typus is reported, when it was found in the Sea of Okhotsk for the first time. This occurrence can be explained by the unusually high sea surface temperature during the summer of 2012. [ABSTRACT FROM AUTHOR]
