The Gulf of Mexico deepwater ecosystem collapsed after the 2011 Deepwater Horizon oil spill.
A PNAS study reported animal populations fell 60-85% within three and a half years.
Octopus, krill, squid and shrimp declined sharply, with krill and lanternfish hardest hit.
Researchers warned the die-off could create genetic bottlenecks that impede ecosystem recovery.
In 2016 BP agreed to a $20.8 billion settlement, including up to $8.8 billion for restoration.
