Rodents are mammals of the order Rodentia, characterized by two pairs of continuously growing incisors, one pair in the upper jaw and one pair in the lower jaw. About forty percent of all species of mammals are rodents, and they are found on all continents except Antarctica. They are the most diversified mammalian order, including mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs and hamsters. There are arboreal, burrowing, and semi-aquatic species. While the largest species, the capybara, can weigh as much as 66 kg (146 lb), many rodents weigh less than 100 g (3.5 oz) and have robust bodies, short limbs and long tails. They use their sharp incisors to gnaw food, defend themselves, and shape their habitat. Most eat seeds or other plant material. Many rodents live in societies with complex forms of communication, and can be monogamous, polygynous or promiscuous. The rodent fossil record dates back to the Paleocene on the supercontinent of Laurasia. ( Full article... )
| | Westward Ho! is an 1855 British historical novel by Charles Kingsley, set in the Elizabethan era and written in a mock Elizabethan tone. It follows the adventures of Amyas Leigh, who sets sail with Francis Drake and other privateers to the Caribbean, where they battle with the Spanish. Originally targeted at adults, Westward Ho! was deemed suitable for children due to its mixture of patriotism, sentiment and romance, and became a firm favourite of children's literature during the 19th century. It has become less popular in the 21st century because of its anti-Catholicism and its racist attitudes towards indigenous peoples. This photograph shows the cover of an 1899 edition of Westward Ho! published by Frederick Warne & Co., with an illustration of two characters engaging in a sword fight.
