The zoo welcomed the hatchlings on June 16 and on June 22, and is the result of "product of more than a decade of dedicated effort to successfully reproduce this species, grow the population and ...
A study on the evolution of tortoise body size over the past 23 million years is published by Joos et al. (2022), who report evidence of limited variation of tortoise body size until the reduction of both mean body size and maximum body size in mainland tortoises in the Early Pleistocene and in island tortoises in the Late Pleistocene and Holocene.
As of December 2023, of the 157,190 species currently on the IUCN Red List, 9,760 of those are listed as critically endangered, with 1,302 being possibly extinct and 67 possibly extinct in the wild.
