Within the wild, tortoises have a way more troublesome life than these in captivity. There’s extra competitors for meals, and so they should keep protected from predators, reproduce in harmful environments, hibernate, and defend their territory.

Previous tortoises can have scratches, dings, and dents of their shells, which may point out age. As well as, if their shells look worn clean, it may additionally point out older age. Nonetheless, scrapes and dents are much less dependable as an indicator of age, as a fall from top might trigger shell harm, even in younger tortoises.
5. Test the High quality of the Scutes
There’s a fantasy that counting the rings on tortoise scutes (shell plates) can let you know how previous they’re, just like counting the rings in a tree. That is, sadly, not a dependable solution to age your tortoise; the rings of progress on the scutes present intervals of excellent diet and quick progress moderately than years handed.
For instance, a tortoise with 10 rings on its scutes could possibly be 5 or 30 years previous, relying on its food regimen. Taking a look at how worn the scutes are generally is a higher manner of estimating age, however this will solely work for older tortoises.

Tortoise Life Phases
Tortoises have 4 life phases, starting with an egg and ending as a completely grown grownup tortoise. These phases can take completely different lengths of time relying on the species of tortoise, however the most typical pet tortoises (Hermann’s Tortoise, Purple-Footed Tortoise, Spur-Thighed Tortoise) are all comparable.
Gestation & Stage 1
The gestation interval has an enormous vary, with some eggs taking 3 days to look and a few taking 3 years! As soon as the feminine lays the eggs, they’re coated and incubated for round 8–12 weeks. Eggs within the nest are the primary stage, and so they should be incubated on the proper temperature for the newborn tortoises to develop appropriately.
Stage 2
Hatchlings are the second stage, and so they appear to be tiny, totally fashioned tortoises. The intercourse of the hatchlings is decided through the temperature the eggs had been incubated; this course of (often called environmental intercourse dedication) produces males at decrease temperatures and females at larger temperatures. Subsequent, the tiny tortoises crack the eggs utilizing a small progress on their nostril referred to as an egg tooth.
Phases 3 & 4
Hatchlings will want loads of sustenance to thrive, guaranteeing their progress into the third and fourth life phases: juvenile and grownup. The one actual distinction between these phases is sexual maturity, which takes round 5 years however can take longer or sooner, relying on the species.
Grownup tortoise shells are laborious and have seen progress rings; they’re bigger and may reproduce. Do not forget that most tortoises can stay for 50 years, many stay to over 100, and there are even species which have lived for almost 200 years!
