A sea turtle mandala coloring page for adults. The shell is laid out as a mandala of petals and concentric rings, and the same geometric patterning carries through the flippers and head, giving you dozens of small compartments to work through one at a time. Many people find that kind of slow, repetitive coloring a good way to settle the mind. Free to download and print as a PDF, with no registration.

Have you ever watched a sea turtle come ashore to nest?
Did you know you can swim alongside sea turtles in the waters off Yakushima and Okinawa in Japan?
Did you know sea turtles return to the beach where they hatched?
Do you take an interest in marine conservation work?
Where do sea turtles lay their eggs?
Females return to nest on the stretch of coast where they hatched, often decades later — a behaviour known as natal homing. They come ashore at night, dig a chamber in the sand and lay around a hundred eggs at a time. In Japan, Yakushima, the Nanki coast of Wakayama and the Ogasawara Islands are among the best-known nesting grounds.
How long do sea turtles live?
A long time — fifty to eighty years or more is the figure usually given, though nobody has ever followed a single wild turtle from hatching to death, so these remain estimates. Very few hatchlings make it that far: the survival rate most often quoted is around one in a thousand, itself an estimate rather than a measured number. A turtle that does reach adulthood, however, has a good chance of a very long life.
Is it true that the temperature of the sand decides a turtle’s sex?
Yes. Sea turtles have what is called temperature-dependent sex determination: the temperature of the sand while the eggs develop decides whether the hatchlings are male or female, with warmer nests producing more females. On some beaches, researchers are now recording strongly female-skewed hatches as sand temperatures climb.
