Comments from Peter Brezaitis

1) Vipera berus is a thick bodied snake relative to other species of snakes in Europe, however as compared to other species of vipers such as Bitis gabonica and Bitis Arietans it is a moderately thick bodied snake.

2)"Adults grow to 60 cm in length with an average of 55 cm. Maximum size varies per region. The largest -- over 90 cm -- are found in Sweden; specimens of 104 cm have been observed there on two occasions. In France and Great Britain, the maximum size is 80-87 cm.[2]" Is this important? The average size is important, the reference needs to be checked. If males are larger than females, and the size difference between males and females is important. Are the largest animals males or females" Were they sexed? Point is that there sexual dimorphism.

Peter has gone off now, will print out article and e-mail in comments which I will append. Nancy Sculerati 18:59, 22 April 2007 (CDT) PS- for "who is Peter Brezaitis?" see ISBN 0-8129-6790-9

Interesting fellow; he writes well, so let's hope he decides to help out! I'll add comments about body build and sexual dimorphism: with V. berus, the females are always relatively larger and heavier than the males (sexing snakes is not that difficult). As for mentioning the maximum size(s), why not? It's to give readers a clear indication of where reality stops and fantasy begins. The corresponding (in-line) references are always at the end of each sentence or paragraph. --Jaap Winius 20:08, 23 April 2007 (CDT)

He'll be making more comments, but his point about maximum size and geographic range is partly that we have to check that the same sexwas comnpared at different portions of the range, since females are large, so if females from one area are compared to males of another (or nobody checked the sex, they just recorded a few snake's length) that the data is meaningless. He's a cool guy. Nancy Sculerati 20:17, 23 April 2007 (CDT)
