"Endangered Species, presents information on endangered and threatened mammals, birds, reptiles, amphibians, fish, mollusks, insects, arachnids, crustaceans, and plants. Its 240 entries were chosen to give a glimpse of the broad range of species currently facing endangerment. While well-publicized examples such as the American bison, northern spotted owl, and gray wolf are examined, so, too, are less conspicuous--yet no less threatened--species such as the Australian ant, Cape vulture, freshwater sawfish, and Peebles Navajo cactus.
