Three adult gray whales photographed via drone in 2017, 2018 and 2019 in Laguna San Ignacio off the coast of Mexico. The three shots show increasingly skinny whales, a bad sign for an animal that needs to make a 10,000-mile return trip to reach its feeding grounds.

Nearly 400 Gray Whales Have Died Off the West Coast Since 2019

Scientists say the die-off, which is entering its third year, is likely due to a scarcity of food in the animals’ cold water feeding grounds

How the Pandemic Is Undermining Weather Monitoring

Scientists are scrambling to patch the cracks forming in the global marine weather monitoring system

Warming waters cause the sharks to hatch early and underdeveloped, making them vulnerable to predation.

Ocean Warming Threatens Baby Sharks in the Great Barrier Reef

Researchers found the hatchlings of the egg-laying epaulette shark are weakened by rising sea temperatures

Researchers estimate this seagrass found in the Mediterranean could trap about 867 million plastic pieces per year in coastal areas.

Researchers find the Mediterranean species of seagrass collects plastics in fibrous balls that form from its fallen leaves

Lightning strikes over the Atlantic Ocean off the coast of Florida.

Why Are Lightning 'Superbolts' More Common Over the Ocean?

Salt seems to be the reason why bolts are brighter over seas than over land

Researchers are hoping to track the conditions lobsters experience as they travel through the supply chain with an eye to reducing the number that die along the way.

A New Device Tracks Lobsters as They Move Through the Supply Chain

Researchers hope the technology can be used to reduce the number of the crustaceans that die along the way

Dolphins can tolerate freshwater for short periods of time, but they developed painful lesions after the storms as a result of prolonged exposure.

Fatal Skin Disease Outbreak in Dolphins Linked to Climate Change–Fueled Storm Surges

When the porpoises are exposed to freshwater after extreme weather, they develop grisly lesions that can lead to their deaths

The group’s identification also highlights how much of ocean life—even when it comes to the largest sea creatures—has yet to be discovered.

Scientists Eavesdrop on New Population of Blue Whales Singing in the Indian Ocean

Scientists have identified a previously unknown blue whale song, suggesting that a distinct population had long gone undetected

With a population of around 366 whales, 'every individual counts' in coming back from the brink of extinction

A small hike in the water temperature triggers corals to dispel the algae, causing them to bleach and turn a ghostly shade of white.

Some Corals Can Survive Through Relentless Heat Waves, Surprising Scientists

The organisms can recover during a heat wave instead of afterwards, and scientists call it a 'game changer' for conservation of the species

Researchers caught an 81-year-old midnight snapper (Macolor macularis) like the one pictured here off the coast of Western Australia. The fish is the oldest coral reef fish ever discovered.

The study suggests that the island is built from sediment generated by the surrounding coral reef, such as from crushed up dead coral, weathered shells and dried-up microorganisms.

This Pacific Island Is Both Sinking and Growing

Sediment produced by surrounding coral reefs has helped Jeh Island outrace rising sea levels

Marine mammals could contract the virus through their mucus membranes, like their blowholes, eyes and mouths.

Can Marine Mammals Catch Covid-19 via Wastewater? The Evidence Is Murky
