Legs and feet: Front legs and feet are flat and shovel like which helps them dig their burrows, back legs and feet are elephantine.
No webbing is present between toes.
Three key requirements:
1. Dry upland habitat with sandy, well drained soils for ideal burrowing and nesting.
2. Open tree canopy so that plenty of sunlight reaches the ground.
3. Low growing food plants for their herbaceous (plant-only) diet including gopher apple and purple love grass.
Mating Season: April through July
Females reach between 10-20 years old.
Females lay a clutch of 4-7 ping-pong ball sized eggs which are buried in the ground. Gestation:80-100 days
Sex is determined by temperature of the soil. Eggs> F 85 (30C) develop into females, < 85 F develop into males.
Hatchlings are 1-2 inches (3-5cm) and grown 3/4 inches a year.
Gopher tortoise burrow provide a home and refuge to over 350 vertebrate and invertebrate species.
Many share the burrow with the tortoise or use abandoned burrows.
Used to regulate body temperature and as shelter from predators and wildfires.
Up to 50ft (15 m) long and 15ft (5 m) deep, depending on water table. Width is about the length of the tortoise.
Aron (or Mound) in front of the burrow is often used as nesting site.
Multiple burrows may be used by individual tortoises.
Burrows provide shelter from heat, cold, fire and safe place to raise young.

Also see . . . Gopher Tortoise. opher tortoises are long-lived reptiles that occupy upland habitat throughout Florida including forests, pastures, and yards. They dig deep burrows for shelter and forage on low-growing plants. Gopher tortoises share these burrows with more than 350 other species, and are therefore referred to as a keystone species. Conservation of gopher tortoises depends not only on the efforts of FWC and other conservation groups, but also on Florida's citizens. There are many ways to co-exist with these gentle land tortoises. (Submitted on July 29, 2017, by Sandra Hughes of Killen, Alabama, USA.)
