How they manage to process this food to porridge and despite of a stomach temperature of 39°c, it does not taint, and it is still unknown.

The food has and it also passes to the gizzard. The proventriculus also starts to digest the fish and crustaceans before it passes to the gizzard. The proventriculus is also the second part of the penguin stomach.

King penguins can take 20 kg of food in one meal. That is 1-5 times their own weight. They need large reserves, but they also need to feed their chicks too. Sometimes, penguins also eat little stones to increase their digestion.

For the chicks this would be a catastrophical and therfore, penguins are also able to stop the digestion and even after three days (adelie penguins) they can bring back fresh food to feed the chicks.

Penguins have crops (special pouches in their throat) that they use to store food in for their babies. They fill their crop with shrimp or fish and take it back to their nest and give it to their babies. The proventriculus is a part of the stomach in penguins that digests the enzymes.

Penguins have an unusually long oesophagus because their stomach is located so low in their body, virtually between their knees. The stomach is a big muscular bag that has a glandular lining in the top part and a folded, muscular part in the bottom.

Occasionally, penguins swallow little pebbles that might aid their digestion of fish, squid, or crustaceans. While a penguin has no teeth, the food goes directly to the stomach. Here it is stored for regurgatation as food for the chicks or for digestion.

Most penguin species can eat 1/4 of their body weight in one meal. Their stomach starts direct under their neck and goes down like a big sac. Penguins have a very fast digestion and can transform the content of their entire stomach in energy in less than 6 hours.

The liver and pancreas produce the necessary elements to aid the digestion. The pancretic juice delivers, among other functions, by carbonates for the regulation of the acidity in the stomach and supplies enzymes for digestion. From here, the almost digested food leaves the body.
