Abstract
Allotriophagy refers to the consumption of food items considered abnormal for a given species. In this note, we report the recurrent consumption of bread and cookie crumbs by a free-ranging worm lizard (Amphisbaena sp.) in Brazil. While there are a few isolated reports of worm lizards consuming unusual food items, this is the first documented case of such behavior occurring over several months, potentially involving the same individual. Allotriophagy in wild worm lizards may be triggered by nutritional deficiencies or opportunistic feeding. Documenting these cases is important for advancing our understanding of worm lizard behavior, particularly in urban environments.
