Osteophagy by the desert tortoise (Gopherus agassizii).

摘要

The desert tortoise (Gopherus agassizii) has undergone significant declines in the past several decades. Thus, many carcasses are present across the desert landscape. Here we report on osteophagy by the desert tortoise, specifically the consumption of bones from deceased desert tortoises. Desert tortoises seem to have an appetite for calcium-rich substances. To our knowledge, this is the first documentation of desert tortoises consuming conspecific skeletal remains.
