- Seal Facts - Woods Hole Oceanographic Institution
Seals like this one photographed during the Sea Ice Physics and Ecosystem Experiment (SIPEX-II) in Antarctica, depend on sea ice to survive They hunt for food, such as fish and krill, under the ice, and use the ice surface for rest and to have their pups (Photo by Peter Kimball, Woods Hole Oceanographic Institution)
- Weddell seals in the Antarctic strategically time their most extreme . . .
New research shows Weddell seals avoid making extreme dives for prey during midday, allowing the seals to keep diving over and over without having to pause for long This allows them to spend almost all of their time underwater, foraging under high-light conditions, which is best for visual hunters (Michelle Shero, ©Woods Hole Oceanographic Institution)
- The Return of the Seals – Woods Hole Oceanographic Institution
WHOI biologist Rebecca Gast examines whether the recovered and thriving population of gray seals in Cape Cod waters has affected water quality off the beaches they frequent
- Seal Whiskers Inspire Marine Technology - Woods Hole Oceanographic . . .
Could seals also use their whiskers to “feel” the surrounding water patterns to track fish that swim by? In the early 2000s, marine biologists at the University of Rostock in Germany began to explore that theory They conducted experiments in which they placed a blindfold and earmuffs on a seal
- Studying How Seals Adapt to Extreme Environments Could Lead to Benefits . . .
However, seals appear to manipulate how glucose is transferred between maternal and fetal blood differently from all other animals studied to date and may provide insight into early intervention for human pregnancies with gestational diabetes, the article indicates
- Creature Feature: Elephant Seal - Woods Hole Oceanographic Institution
About Elephant seals You may have seen (and heard) elephant seals on a beach: roaring, clumsy and (let’s face it) terrifying as they jostle for mates These enormous, blubbery marine mammals awkwardly belly-flop around on land, but are elegantly adapted for life in the twilight zone—where they spend 90% of their at-sea time Two distinct species, the Northern and Southern elephant seal
- About Elephant seals - Woods Hole Oceanographic Institution
Elephant seals’ large eyes are specialized to detect bioluminescent glimmers in low light, but they rely just as much on other senses to hunt and escape sharks and orcas in the twilight zone Their inner ears have adapted to amplify sound and adjust to pressure changes, while their whiskers (called vibrissae) help the seal locate prey and navigate—much like a cat’s whiskers
- How Do Marine Mammals Avoid the Bends? - Woods Hole Oceanographic . . .
Deep-diving whales and other marine mammals can get the bends - the same painful and potentially life-threatening decompression sickness that strikes scuba divers who surface too quickly A new study offers a hypothesis of how marine mammals generally avoid getting the bends and how they can succumb under stressful conditions
