baby boa umbilical line

[richardhind]

Hi there
just wondered how long till the line where the umbilical cord was disappears?just wondered as ive got an 9 week old with line and a supposed 10 month old boa where i can still see the line also.they the same size and im not sure whether there about the same age or are 8 months apart,she seems quite small for nearly a year old,compared to the other male,she may just be a slow starter.
cheers richard
