Antarctic sea ice is more than just a platform for penguins. The sea ice's high reflectivity influences the whole Earth's ...

Nature has innumerable life-threatening predators who might be smaller in size or may have an innocent-looking appearance. While most people are familiar with lions, wolves, and sharks, the world is ...

Researchers measured the amount of nitrogen and carbon in the whiskers, which tells them the kinds of animals the leopard ...

Acoustic data from krill fishing vessels, analyzed with machine learning, identify when and where fishing overlaps with krill predators such as whales, penguins, and seals in the Southern Ocean.

Bahlburg D, Menze S, Krafft BA, Lowther AD, Meyer B: Mapping encounters between Antarctic krill fishing vessels and air-breathing krill predators using acoustic data from the fishery, Proceedings ...

Antarctic krill is a key species in the Antarctic marine ecosystem: it is an important food source for many species, such as whales, seals and penguins. However, the small crustaceans are ...

Interestingly, the krill also appeared to lose their appetite in the presence of penguin poop, feeding 64 percent less efficiently than under normal conditions. ( Penguins don't live at the South ...

We thus expect krill to show similar swimming behaviors and suppressed feeding around seals, whales, and other types of krill predators in Antarctica,” said Hellessey.

Krill use their antennae to sniff out food, mates and even pollution. But scientists weren’t sure if they could detect predators by scent. To find out, Hellessey and her colleagues netted krill ...

Imagine looking at the world through the stalked compound eyes of krill in the Southern Ocean. All of a sudden, a penguin appears like a voracious giant, streamlined like a torpedo, chasing and ...
