Sea creatures may exhibit the spiraling behavior to navigate the ocean, for mating rituals, or to track prey

The water high in salinity slowly poisons trees, and as they die, all that is left behind are ghostly gray trunks that resemble toothpicks.

'Ghost Forests' May Become More Common as Sea Levels Rise

East Coast woodlands are left parched as brackish water encroaches on landscapes

Ocean creatures are noisier than scientists first thought.

Biologist Marie Fish Catalogued the Sounds of the Ocean for the World to Hear

Scientists once thought marine life kept quiet. Then the Navy tapped an aptly named researcher with an open mind

For decades there were rumors of leaking barrels filled with the pesticide DDT littering the ocean floor off the coast of Santa Catalina Island dumped by the now-defunct, Montrose Chemical Corp, the largest global DDT manufacturer based in Los Angeles

'Underwater Roombas' Scan Southern California Coast for DDT Barrels

Hundreds of tons of the toxic chemical have likely littered the ocean floor near Santa Catalina Island for decades

Partially protected areas are often proposed as a way to bolster marine life and to improve people’s enjoyment of the ocean—neither of which seems to be happening.

Partially Protected Marine Areas Have Little Benefit, Scientists Say

Compared to fully safeguarded marine protected areas, the zones don't show a lot of positive effects for marine life or people’s enjoyment

Sea beans, otherwise known as sea asparagus and pickleweed, belong to the genus Salicornia, marsh plants that thrive in salty soils.

The cyanobacteria species that produces gatorbulin-1, tentatively identified as Lyngbya confervoides, forms these reddish-green, hair-like structures which are a collection of connected single cells rather than a true multicellular organism.

Scientists Find Blue-Green Algae Chemical With Cancer-Fighting Potential

The discovery shows how studying marine biodiversity can enhance biomedical research.

The ring-shaped coral islands known as atolls, like this one in the Maldives Islands in the Indian Ocean, may trace their formation to sea levels repeatedly rising and falling over hundreds of thousands of years, geologists say.

Why Some Geologists Say Charles Darwin's Theory of Coral Atoll Formation Is Wrong
