Description
Adélie Antoine and nine co-authors follow mother Weddell seals hunting under Antarctic sea ice in a 2023 study from Terre Adélie, East Antarctica. Feeding a pup is the most costly part of a seal's life, yet fine detail on how mothers hunt was scarce.
In 2019 the team fitted three nursing females with sonar tags for seven days. The seals spent most of their time hauled out on the ice. Dives were shallow compared with other seasons, and all feeding lunges took place on the seafloor. The tags logged 331 prey capture attempts, with 125 prey sized on the sonar echoes. Half the prey fought back or fled. The study gives a close view of how these mothers balance feeding themselves and their pups.
