The S. magellanicus or Magellanic penguin is a South American penguin, breeding in coastal Patagonia, including Argentina, Chile, and the Falkland Islands, with some migrating to Brazil and Uruguay, where they are occasionally seen as far north as Espirito Santo.

S. magellanicus or Magellanic penguins are medium-sized penguins which grow to be 24–30 in. tall and weigh between 6.0 and 14.3 lb. The males are larger than the females, and the weight of both drops while the parents raise their young.

Adults have black backs and white abdomens. There are two black bands between the head and the breast, with the lower band shaped in an inverted horseshoe.

The head is black with a broad white border that runs from behind the eye, around the black ear-coverts and chin, and joins at the throat.

Like other species of penguins, the Magellanic penguin has very rigid wings used to swim under water.

S. magellanicus or Magellanic penguins feed in the water, preying on small pelagic fish, hagfish, cuttlefish, squid, krill, and other crustaceans, and ingest sea water with their prey. Their salt-excreting gland rids the salt from their bodies.

Adult penguins can regularly dive to depths of between 20 m to 50 m deep in order to forage for prey.

During the breeding season males and females have similar foraging and diving patterns as well as diet composition, however bone tissue analysis suggests that diets diverge post-season when limitations imposed by chick rearing are removed.

S. magellanicus or Magellanic penguins do not experience a severe shortage of food like the Galapagos penguins, because they have a consistent food supply being located on the Atlantic coast of South America.

The presence of the large continental shelf in the Atlantic Ocean lets Magellanic penguins forage far from their breeding colony.

Jellyfish including species in the genera Chrysaora and Cyanea were found to be actively sought-out food items, while they previously had been thought to be only accidentally ingested.
