The bountiful creatures sequester carbon and are a vital food source for marine predators, but their future is uncertain ...

The penguin poop didn’t only influence krill movements. In another phase of the experiment, researchers noticed the ...

A keystone prey species in the Southern Ocean is retreating towards the Antarctic because of climate change. Krill are small, shrimp-like creatures that swarm in vast numbers and form a major part ...

The foul stench of penguin poop sets Antarctic krill on edge. In lab experiments, the mere scent of penguin droppings — or guano — sent krill scrambling for escape, researchers report March 20 in ...

The study suggests that even the faintest hint of penguin droppings in the water is enough to prompt krill into escape ...

“Here we show for the first time that a small amount of penguin guano causes a sudden change in the feeding and swimming ...

Recent times have seen an increase in the demand for Antarctic krill oil due to the numerous health benefits it offers. This oil, derived from small shrimp-like organisms known as krill that dwell ...

“Here we show for the first time that a small amount of penguin guano causes a sudden change in the feeding and swimming behaviors of Antarctic krill,” said Dr. Nicole Hellessey, a postdoctoral ...

A species such as krill (Euphausia superba), which is the largest wild animal species by collective biomass, is not only the keystone species of the Antarctic ecosystem, preyed upon by many higher ...
