African penguins feed on anchovies Engraulis japonica and sardines Sardinops ocellata (two types of fish) in the Benguela current. This is a cold water ocean current found close to their islands off South Africa. They can travel for as far as 100 miles to fish for food and usually travel in groups of 8 or more. Penguins feed on as much as 12-15% of their body weight. This is equivalent to a 150 pound human eating 80 hamburgers in one meal. Penguins burn through calories quickly, it takes a lot of energy to keep their body temperatures warm while swimming in the cool waters. Their internal temperature is 102-103 degrees Fahrenheit and the water they swim in can be 48-60 degrees Fahrenheit. We feed our penguins every day at 10:30am and 3:30pm.
