Including the addition of 40 new species, this 2nd edition is completely updated to reflect the changes in endangered and threatened status. Color photographs and maps provide students with many species threatened by extinction, including amphibians, birds, crustaceans, fish, insects, mammals, mollusks, reptiles and more. Each of the 240 entries gives a species description, location, reason for endangerment and measures being taken to protect it. (19991001)
