The carcass of a Steller sea lion washed up this weekend in Unalaska's Morris Cove.

The dead marine mammal was an adult male, almost eight feet long, according to Melissa Good of the Alaska Sea Grant program.

Good said it's unclear why the animal died.

She found it on the beach Saturday in a moderate state of decay.

In an effort to figure out what’s behind the mysterious decline of Steller sea lions, scientists are trying out crowdsourcing for the first time. The project is called Steller Watch. The idea is to convince the public to comb through pictures looking for sea lions.

Alaska’s endangered Steller sea lion population continues its precipitous decline. The 2016 survey by the National Oceanic and Atmospheric Administration (NOAA) shows an overall increase in the number of Steller sea lions across Alaska, but a mysterious drop in parts of the western stock.
