Frogfish can be found almost worldwide, but it is very unusual for one to appear in the cold Tohoku region, for they prefer the tropical and subtropical waters often above 20 degrees Celsius (68 degrees Fahrenheit). When this spotfin frogfish was found, the water temperature was 9 degrees Celsius (48 degrees Fahrenheit)! According to the researcher, it is likely that this is the northernmost appearance of spotfish frogfish.
