文摘
- •
Behaviour was recorded in free-ranging lizards of different age classes.
- •
Redder (less orange) lizards took more risks by staying further from refuge.
- •
This is consistent with red coloration being an antipredator mechanism.
- •
Rate of tail and limb display was not significantly related to coloration.
- •
This is not consistent with red coloration having a pursuit deterrent function.
