The Book of Frogs
With over 7,000 known species, frogs display a stunning array of forms and behaviours.
A single gram of the toxin produced by the skin of the Golden Poison Frog can kill 100,000 people. Darwin's Frog males carry their tadpoles in their vocal sacs for sixty days before coughing them out into the world.
The Wood Frogs of North America freeze every winter, reanimating in the spring from the glucose and urea that prevent cell collapse during the cold months. 656 pages.
