Book Description
Steller's classic work, published in Latin in 1751 and in German in 1753, contains the only scientific description from life of the Steller's sea cow (Hydrodamalis gigas), as well as the first scientific descriptions of the fur seal or "sea bear" (Callorhinus ursinus), Steller's sea lion (Eumetopias jubatus), and the sea otter (Enhydra lutris). Steller's sea cow was a sirenian, or manatee, inhabiting the North Pacific Ocean and Bering Sea. It was first discovered by Europeans in 1741 and rendered extinct by 1768. It was a 30-foot long, plant-eating aquatic mammal, weighing up to 12 tons, that lived in large herds on the coasts of Alaska and Kamchatka. Steller made his observations as part of Vitus Bering's second voyage, during which the crew was shipwrecked for 9 months on Bering Island, from November 1741 to August 1742.

Book Description
An insider's view on bringing extinct species back to life Could extinct species, like mammoths and passenger pigeons, be brought back to life? In How to Clone a Mammoth, Beth Shapiro, an evolutionary biologist and pioneer in ancient DNA research, addresses this intriguing question by walking readers through the astonishing and controversial process of de-extinction. From deciding which species should be restored to anticipating how revived populations might be overseen in the wild, Shapiro vividly explores the extraordinary cutting-edge science that is being used to resurrect the past. Considering de-extinction's practical benefits and ethical challenges, Shapiro argues that the overarching goal should be the revitalization and stabilization of contemporary ecosystems. Looking at the very real and compelling science behind an idea once seen as science fiction, How to Clone a Mammoth demonstrates how de-extinction will redefine conservation's future.
