My Italian fire salamander

[Jimin]

Can the yellow pattern widen as my salamander grows? I wonder if there are yellow patterns that didn't exist.

Bright colours have a key role for animal defense and can be expressed through metabolic production or by acquiring pigments from diet.

Adult show strong variation of colour pattern; variation was strongly related to the individual's size, to habitat productivity and to food availability. Under common garden conditions, differences between populations were not anymore evident, and coloration was only affected by resource availability during larval development.

Environmental conditions and food availability are more important than local adaptations in determining differences in aposematic colour pattern.
