CROCLIST: morphometric studies in black caiman

[Francisco Villamarin]

Hello all,
I´m studying the nesting biology of black caiman. Does anybody know about 
any study related with morphometric relationships in this species?? I´m 
trying to determine the actual size of a female from a picture of it 
standing by its nest (I know the nest size). My problem is that I´ve got a 
picture of the female in front view so I need to know the relationships 
between craneal measurements (long and wide).
Thank you in advance.
Pancho!
