Buehr sticks to the sober and sensible examination of reports from early sailors to the present in describing the strange and monstrous marine life suspected to exist. His musings about sea monsters tend toward the scientifically possible explanations of where and how the huge and unidentifiable creatures could survive. Not at all sensational, this is more like a sifting of the evidence. The result is an exercise in assessing the authority of witnesses who might have been seeing through a screen of fear, ignorance and hysteria. As is usual with this author/ illustrator's books, the text is straightforward and interesting and his illustration's are careful and graphic.
