An introduction to the history of dolphins an aquatic mammal

Is a dolphin a mammal?

Old-fashioned indeed—whales are mammals, not fish.

Thankfully, our scientific understanding of whales has come a long way sinceand much of that knowledge is collected in Whales, Dolphins, and Porpoises, a sperm whale-sized compendium of all things cetacean. Some whales release a ring of bubbles to corral their prey, and recent research suggests that bowhead whales may live for more than years.

Whales, Dolphins, and Porpoises, edited by whale biologist Berta, explains the diet, conservation status, and a host of other details for each of the 89 species of cetacea. This guide is a fantastic resource for biologists and aquatic-mammal watchers alike.

There is a sequence of illustrations showing what each species looks like above water as it dives. This informative and captivating book will be a fine addition to libraries that serve everyone from laypeople to researchers and scientists who are interested in learning more about marine mammalogy, in particular the titular species.

Although there is no shortage of guidebooks that focus on cetacean species, Whales, Dolphins, and Porpoises: A Natural History and Species Guide gives homage to the diversity of this taxonomic group through its large page size, ample species-specific illustrations, and efficiently organized authoritative text.
