Wildlife of Antarctica

Orcas regularly feed on penguins in Antarctica

Although orcas are known to predate penguins further north, around sub-Antarctic islands, this is the first time they have been seen hunting the birds in Antarctic continental waters.

What is more, the orcas seem to be particularly choosy about which bits of the penguins they eat; being inclined to take only the best cuts of penguin breast meat.

Antarctic Wildlife – British Antarctic Survey – lots of information

Whales and seals of the Southern Ocean have been severely exploited by man in the past, but are now mostly protected. Some seals and whales have had dramatic population increases in recent decades, though others remain greatly reduced compared to pre-hunting levels. The removal of millions of krill-eating whales and seals had a marked effect on the Antarctic marine ecosystem, and it may be centuries before a new equilibrium is reached.

Wildlife in Antarctica – Lonely Planet

When viewing Antarctic wildlife, it is important to keep your distance. For one thing, the Guidance for Visitors to the Antarctic requires it – and it’s important for your personal safety. Your presence changes the ­animals’ behavior, so the further back you keep, the more natural the animal will act. While wildlife may not seem to be concerned about your presence you may in fact be causing it considerable stress. A single thoughtless gesture can cause the loss of an egg or chick to a predator, or the crushing of a seal pup by a frightened adult. Another reason to keep back is that your photos won’t turn out as well if you press in too close – the animals are more likely to move, blurring your picture.

First nearshore survey of Antarctic krill reveals high density, stable population in shallow waters

Using smaller vessels that allow access to shallow, nearshore waters, researchers conducted the first multi-year survey of the population of Antarctic krill (Euphausia superba) in coastal waters and discovered that nearshore waters had significantly higher krill biomass density than offshore waters. They also found that the nearshore waters had less interannual variation than offshore waters.
