Penguins play a cat-and-mouse-game with their prey. They start looking for fish by diving at a rate of 5 till 10 km/hr and under an angle of 5 degree till 85 degrees. On a certain depth they either swim a while horizontally or they ascend again under the same angle.Of course the fish tries to escape.While penguins need air to breath, they have to go to the surface of the water after a few minutes. Luckily for them, their prey can't dive deeper either, because the lack on oxygen and food so deep in the water.o find out when and where penguins eat what, scientists of the Alfred-Wegener-Institut fuer FÃ¼r-polar Und meeresforschung developed a special. Sensor a penguin is an-warm blooded (animal body temperature is aboutÂ°39), c but their prey has only a temperature of -about Â°2 c + till Â°13. c
