NOAA Fisheries recently reported that a young male Hawaiian monk seal -- RK88, also known as "Kuokala" -- has passed away.

He was found dead at Camp Erdman, Ka'ena Point on August 21. Test results rule that his death was due to drowning in a lay gill net.

"RK88's nutritional condition was being closely monitored earlier in the year, but he was sighted regularly in the weeks prior to his death in good body condition," NOAA reported. 

Other tests confirmed that RK88 was healthy at the time of his death, and there was no evidence of disease or other health concerns.

NOAA encourages the public report illegal gill nets to the Hawaii Department of Land and Natural Resources hotline at (808) 643-DLNR (3567).
