Amphibians and reptiles have adopted almost every habitat and every device for survival. Humans, however, are irrationally prejudiced against them. ‘Cold-blooded’ is a term of dislike, though their blood is not cold at all - merely on occasion cooler than ours. They offer no threat unless, perhaps, when trodden on or cornered. Of all groups, surely the reptiles deserve our better understanding and this is what Sir David offers, with greater enjoyment along the way. Few people will read him unmoved or unenlightened.
