Weddell Seals Time Their Hunts Strategically
New research from the Woods Hole Oceanographic Institution (WHOI) and partners reveals that Weddell seals that inhabit the icy waters of Erebus Bay, Antarctica employ a careful hunting strategy when it comes to diving, timing their dives to balance energy use and foraging efficiency.
The study, published in Communications Biology, shows that the seals perform their longest and deepest dives early in the day, and not during midday when sunlight is at its peak.
