Federal officials are looking for the two swimmers who were seen riding a dying whale in South Florida, Local 10 reports.

The National Oceanic and Atmospheric Administration asks anyone with more information to call their hotline (800-856-1964).

According to published reports, a Pompano Beach resident snapped a picture of one man riding the dying whale Sunday morning. The swimmers could face a misdemeanor conviction of harassing a marine mammal, which carries a maximum penalty of one year in jail and a fine of up to $100,000.

City officials had the 40-foot sperm whale carcass towed out to sea rather than allow scientists to perform a necropsy.

Federal officials argued that learning the animal's cause of death would provide invaluable information for conservation.
