Frequently asked questions
Is a tortoise a turtle?
Yes. All tortoises are turtles (members of order Testudines), but not all turtles are tortoises. Tortoise refers specifically to terrestrial herbivorous turtles with domed shells.
Which is easier to keep?
Aquatic turtles have lower lifespan commitments but heavier housing requirements (large filtered tanks). Tortoises live much longer but housing is simpler structurally.
What's the largest turtle?
Leatherback sea turtle — up to 7 ft and 2000+ lbs. Among popular pets, Aldabra giant tortoise (up to 550+ lbs) is largest.
Why do tortoises live so long?
Slow metabolism, low reproductive demand, evolved longevity. Some species exceed 150 years.
Can a tortoise swim?
Most cannot. They are land animals with weight-bearing legs, not swimming adaptations. Tortoises can drown in water.
