The animal on the cover of Practical PostgreSQL is a mammoth. Mammoths (of the genus Mammuthus) inhabited the Earth during the last Ice Age, which ended about 10,000 years ago. There are several types of mammoths, such as Colombian and Imperial, but the best known is the woolly mammoth. Mammoths resided on the tundra of Asia, Europe, and North America. They are believed to have migrated to North America over the Bering Strait land bridge.

Known for their large size, mammoths ranged from 12 to 15 feet tall at the shoulder and weighed as much as 6 to 8 tons. They had long, dense hair and under fur, long trunks, and large ears. Their most prominent features were long, curved tusks that measured up to 16 feet. Mammoths used their tusks for digging underneath the snow to find food, for protection, and in mating rituals. As herbivores, they ate leaves of willow, hornbeam, fir, hazel, and alden. They lived up to 60 years in age.
