Some animal species congregate in huge groups. Icelandic puffins form colonies of more than a million, which provides shared information about food sources and reduces the odds of being attacked. Social spiders in Ecuador gather by the thousands to capture large prey. Leaf cutter ants in Costa Rica build enormous acre-wide cities to house multimillion-citizen colonies.
