A tortoise grows surprisingly fast during its first few years of life. For example a gopher tortoise (Gopherus polyphemus) hatchling that weighed only 21 grams in September can reach a weight of 1000 grams by the following May (Degenhardt et al. 1996). That’s a growth rate of nearly 50 grams per month!
As tortoises age their growth rate begins to slow. Young adult tortoises may continue to grow for several years but the rate of growth gradually decreases until it levels off in adulthood. After that tortoises only put on weight in response to conditions like pregnancy or drought (Dodd 2000).
Why do tortoises grow so quickly when they’re young? It’s thought that their rapid growth helps them survive and thrive in the wild. For example young tortoises must be able to outrun predators and escape being eaten. They also need to be big enough to defended themselves against other animals like competitive males during breeding season (Dodd 2000).
In captivity tortoises can live for decades and grow to be quite large. For example a sulcata tortoise (Centrochelys sulcata) may reach weights of over 100 kg (220 lb) and lengths of over 1 meter (3 ft) (Ernst and Zug 1996)!
Assuming optimal care a tortoise’s growth rate will depend on several factors including species sex diet and housing. In this article we’ll discuss these factors and how they influence a tortoise’s growth rate. We’ll also give you some tips on how to ensure your tortoise grows as quickly and healthy as possible.
Species: Some tortoise species grow faster than others. For example sulcata tortoises grow much faster than Russian tortoises (Testudo horsfieldii) (Ernst and Zug 1996; Highfield and Martin 1990).
Sex: In many species males grow faster and larger than females (Dodd 2000; highfield and Martin 1990). For example male gopher tortoises (Gopherus polyphemus) can reach weights of up to 4 kg (9 lb) while females only grow to about 2.3 kg (5 lb) (Degenhardt et al. 1996).
Diet: A nutritious diet is essential for optimal growth in tortoises. A diet that’s too high in protein can actually stunt a tortoise’s growth (Bennett 1995).
Housing: Tortoises that are kept outdoors and have plenty of space to roam around tend to grow faster than those that are kept indoors (Dodd 2000). This is likely because outdoor tortoises have more opportunities to exercise and bask in the sun which helps them absorb more calcium and other nutrients.
