Zookeepers talk about the diet needed to keep a gorilla and a penguin healthy. A healthy diet gives the animals energy and helps them to recover from illness. Gorillas are vegetarian and eat a large variety of fruit and vegetables. Chestnut is a six-month-old penguin who has been hand-reared. He eats 20 - 30 fish each day and is very hungry and demanding. If the penguin did not eat he would lose body weight, become ill and eventually die.
After watching this clip, children could match the animals with what they eat. It may be used to introduce the question of why animals (including humans) need food. An interactive display on animal diets may be supported by this clip and may lead to discussions on why different animals need different foods.
