Scientists used a new research approach to show that warming temperatures are turning one of the world’s largest sea turtle colonies almost entirely female, increasing the risk that the colony will not be able to sustain itself in coming decades.
Sand temperatures determine the sex of turtle hatchlings. Warmer temperatures result in more females, while cooler temperatures result in more males. Although researchers have known for decades that temperatures alter the sex of sea turtle offspring, this is the first time they have directly documented the trend in a major wild population.
During the past two decades, temperatures on islands in Australia’s northern Great Barrier Reef have increased to the point “that virtually no male turtles are now being produced from these nesting beaches,” according to the researchers from the United States and Australia who produced the paper.

Spinner dolphins are best known for their above-water displays of leaping and spinning several times. A single spinning leap can include as many as four body revolutions. Spinner dolphins are found throughout the world's tropical and subtropical oceans. Get more information on this species - https://www.fisheries.noaa.gov/species/spinner-dolphin

Home for the holidays—Three rescued Hawaiian monk seals rehabilitated for malnourishment are now back in the wild, in time to make a fresh, healthy start in the new year.

Today also marks the anniversary of the Endangered Species Act, which was signed on December 28, 1973 and provides for the conservation of species that are endangered or threatened throughout all or a significant portion of their range.

46 scientists and crew aboard NOAA ships Oscar Elton Sette and Reuben Lasker have spent the past 179 days surveying an impressive 1.8 million square nautical miles around the main and Northwestern Hawaiian Islands!
Their research helps @NOAA scientists better understand the structure of whale and dolphin populations and their unique habitats. The teams had the opportunity to encounter and study 23 species of whales and dolphins, including false killer whales—a top priority for the survey— and update data about their population size that will inform bycatch reduction strategies. Scientists also saw several beaked whales during HICEAS, including the rare Longman’s beaked whale, which has only recently been named after spending years with a case of mistaken identity.

Six Kemp’s ridley sea turtles rescued from Cape Cod beaches in recent weeks are recovering at NOAA Fisheries’ Woods Hole Science Aquarium.

The animals, the smallest of the endangered marine turtles, came ashore in November after being cold stunned – a kind of hypothermia – when local water temperatures suddenly dropped.

It's #CoralsWeek! Did you know that coral reefs are the most diverse habitats on the planet? Reefs occur in less than 1 percent of the ocean, yet are home to nearly one-quarter of all ocean species. These ancient structures make a perfect home for millions of species of fish, crabs, clams, starfish, squid, sponges, lobsters, seahorses, sea turtles, and more. That exceptional diversity has given them the nickname, “rainforests of the sea.” Find out more about shallow coral reef habitat from our website: https://www.fisheries.noaa.gov/national/habitat-conservation/shallow-coral-reef-habitat

Did you know coral reefs are home to millions of species? Hidden beneath the ocean waters, coral reefs teem with life. Fish, corals, lobsters, clams, seahorses, sponges, and sea turtles are only a few of the thousands of creatures that rely on reefs for their survival.

Coral reefs are also living museums and reflect thousands of years of history. Many U.S. coral reefs were alive and thriving centuries before the European colonization of the nearby shores. Some reefs are even older than our old-growth redwood forests. They are an integral part of many cultures and our natural heritage.
