Seymour the ageing Giant Bullfrog, shown with a younger cousin, has grown to an unwieldy size at South Africa's Transvaal Snake Park June 3, where he has lived tranquilly for most of his 15-year life. The protected, carnivorous species has become scarce as its natural habitat is destroyed and few live long enough to grow to Seymour's size and weight of nearly one kg (two lbs). The frogs spend most of their lives in a dormant state underground but become active in the rainy season, when many are squashed crossing roads.
