Despite the deadly environmental conditions in the Antarctic, emperor penguins have developed a surviving strategy which allows them to breed the eggs during 4 months of winter time. This is realized by a huddle of huge numbers of tightly grouped penguins. Though no individual has the overview to realize an optimized strategy of the whole huddle, it behaves according to certain rules which are vital for the survive. These rules are found employing a cellular automates model. First, each individual feels attracted by the most nearest and next-but-next-nearest neighbors which creates the attraction of the huddle. If a stress situation occurs like created by external enemy, the individuals cease to see the next-but-next-nearest neighbor but see only the next neighbors which leads to an expel of the crowed. Second, there is a pushing of an individual in front if too many sides of the individual are uncovered.
