  Did you know that there is no precise method of visually determining a tortoise’s age? Some use growth rings on the scutes of the carapace (top shell) to indicate age, but just like growth rings on a tree, a tortoise can develop no rings, or up to several growth rings per season. Others use forelimb size or shell length by measuring the midline carapace length (MCL) to estimate age, but these methods can still be inaccurate, as growth rates and length can vary year to year depending on food availability and environmental conditions. Upon hatching, tortoises emerge at around 45 mm (< 2 inches), and can grow up to 360mm (14.17 inches)! Our biologists estimate age in the field using carapace length at the midline (MCL) paired with other
