A team of marine biologists with the U.S. National Oceanic and Atmospheric Administration's Alaska Fishery Science Center has solved the mystery of why approximately 10 billion snow crabs vanished from the Bering Sea back in 2018/2019—the water there was too warm for them.

Remember those headlines about "90% of snow crabs mysteriously vanish" from a while back?

:desolate:

tl;dr water was too warm which requires more energy (food) for them to sustain themselves, plus too many of them from a previous population boom
