Did you know? An elephant lives on average 60 years. That represents 100 lives of a butterfly. A chicken, on the other hand, lives on average 12 years, which is 3 lives of a fox but also 3 lives of an earthworm... In colorful compositions, Giulia Vetri compares the longevity of animals, with a human presence as a reference. She starts with the shortest, with the famous mayfly, to the longest: bicentennial cetaceans, trees, millennial corals, and the immortal jellyfish... Some pages group animals that share the same longevity, while others present playful equivalences that sometimes create surprises. A captivating documentary section explains the factors that influence the lifespan of a living being: is it male or female? A wild, domestic, or captive animal? Does its natural environment experience upheavals?
