The specimen found in the Baltic measured in at 46 by 72 centimeters (18 by 28 inches) -- relatively small. The largest recorded example of ocean sunfish weighed 2.3 metric tons (5,000 pounds) and measured longer than three meters (10 feet). Researchers at the museum have preserved the fish in formaldehyde and plan to analyze its DNA to determine from which population of fish it came.
