After a decade-long investigation, researchers have uncovered the culprit behind the massive die-off of sea stars, which has claimed billions of lives along the Pacific Coast. The disease, caused by a strain of bacteria known as Vibrio pectenicida, led to the phenomenon where affected starfish disintegrate into a gooey substance. This breakthrough not only clarifies the mystery behind the sea star epidemic but also raises concerns about a potential link to global warming. The findings mark a significant advancement in marine biology, providing hope for conservation efforts aimed at protecting the remaining sea star populations.
