 In 2015 , the Cerro Fatal tortoises were described as a distinct taxon , donfaustoi . Prior to the identification of this subspecies through genetic analysis , it was noted that there existed differences in shells between the Cerro Fatal tortoises and other tortoises on Santa Cruz . By classifying the Cerro Fatal tortoises into a new taxon , greater attention can be paid to protecting its habitat , according to Adalgisa Caccone , who is a member of the team making this classification .
