In honor of World Sea Turtle Day on June 16, 2018, join us for Sea Turtle Week, June 11-15. Sea turtles, also called marine turtles, are air-breathing reptiles with streamlined bodies and large flippers. Well-adapted to life in the marine environment, they inhabit tropical and subtropical ocean waters throughout the world.

Although sea turtles live most of their lives in the ocean, adult females must return to beaches on land to lay their eggs. They often migrate long distances between feeding grounds and nesting beaches. Seven species have been identified worldwide. Six sea turtle species are found in U.S. waters (the flatback sea turtle is found only in Australia and Papua New Guinea).
NOAA Fisheries works with our partners to improve the conservation and recovery of threatened and endangered sea turtles. This #SeaTurtleWeek, we highlight the science we conduct to conserve sea turtles.
Sea Turtle Features
Sea Turtles: Is the Future Female?
Are sea turtles destined to turn all female? This video documents cutting edge research that discovers alarming trends as global temperatures rise, and fewer male turtles are hatching from the nesting beaches.
Hawaiian Hawksbill Turtles: One of the World's Most Endangered Sea Turtle Populations
See what scientists are discovering about the Hawaiian hawksbill sea turtle in their efforts to bring back the endangered population.
Leatherback Turtles: Understanding the Pacific Population
Watch our new video to see how NOAA scientists are studying the Pacific leatherback sea turtle, a NOAA Fisheries Species in the Spotlight.
New Species Named for NOAA Fisheries Scientist
Veterinarian and sea turtle pathologist Dr. Brian Stacy became the first Office of Protected Resources scientist to have a new species named for him.

Cold Snaps and Stunned Sea Turtles
For sea turtles, cold water temperatures can be fatal. Sudden cold snaps or intense, prolonged cold can be very dangerous for sea turtles, especially during the winter.

Chat with NOAA Sea Turtle Scientists
A combination of skeletochronology and stable isotope analysis enables Drs. Larisa Avens and Cali Turner Tomaszewicz to accurately age sea turtles that have stranded and understand where they lived and for how long, what their diet consisted of, and when they had years of slow or rapid growth.Ask NOAA scientists your questions about sea turtles on Tuesday, June 12 at 1-3pm EST.

Celebrating and Conserving Sea Turtles
Every day NOAA scientists and managers work hard to conserve and recover protected species as part of our mission, and sea turtle conservation activities have been a hallmark of those efforts.

Faces of Sea Turtle Conservation
NOAA Fisheries scientists developed a new technique that gives us more insight on sea turtle populations than ever before, extracting life history and other information from sea turtle bones. The technology combines bone dating, or “skeletochronology,” and the sequential sampling of annual growth rings for chemical signatures like stable carbon and nitrogen isotope ratios.
