What four decades of canned salmon reveal about marine food webs
By analyzing 42 years worth of canned salmon, University of Washington scientists show that levels a common marine parasite rose in two salmon species in the Gulf of Alaska from 1979 to 2021. The rise may be a sign of ecosystem recovery, possibly influenced by the 1972 Marine Mammal Protection Act.
Crunch! Underwater Acoustics Expose ‘Shell-crushing’ Sounds in a Large Marine Predator
“Shell-crushing,” an explosive sound, occurs when marine animals crack open hard shells like clams to eat the edible tissue. There hasn’t been any data to support this feeding noise, until now. A study is the first to quantify these sounds using underwater acoustics in a marine animal in a controlled setting. Scientists know what type of shell a ray is eating based on the sound it makes and show it’s audible above ambient noise in lagoons out to 100 meters.
