RE: Squamate shedding question


Shedding frequency is roughly proportional to (growth rate + a constant);
A snake or lizard that is warm enough to be active, but not getting enough
food to grow (and may actually be shrinking, as its tissues and bones are
resorbed to sustain metabolism) will still shed fairly regularly (typically
three or four times a year).

In the presence of abundant food, growth doesn't usually stop at all, just
gets slower and slower.

Do lizards shed only while growing?
