They don't irritate you by being noisy. They have enough sense to stick their heads in their shells when things get too weird. You can watch them online on the live turtle cam . They come in a lot of sizes and colors. Turtles move at a predictably slow and comfortable pace in an unpredictable and frenetic cosmos.
Turtles dig both water and terra firma.
Some of them are endangered species. They seem pretty nice. Baby turtles follow light from the moon and stars to know where to swim when they are first born. I took pictures of them on Grand Cayman Island during spring break. They hatch from eggs like chickens but they have to learn to swim right away.
