Why Coral Reefs May Be the Most Biodiverse Ecosystems on Earth

Maria Faith Saligumba

Imagine plunging beneath the waves into a world bursting with color, drama, and life—a place where creatures of every shape and shade dart, bloom, and battle in a living mosaic. Coral reefs, often called the “rainforests of the sea,” are so much more than pretty underwater landscapes. They’re some of the most densely packed, wildly ...

Sumi

If you feel like you keep hearing about the same few endangered animals over and over, you’re not wrong. Pandas, tigers, rhinos – they dominate the spotlight. But quietly, in forests, oceans, rivers, and even underground, there are other species on the edge of extinction that almost nobody talks about. And if they vanish, they’ll ...

5 Unbelievable Animal Abilities That Science Still Can’t Fully Explain

Sumi

Some animals pull off feats so strange they sound like urban legends until you see the footage or read the data. They sense earthquakes before they happen, find their way across entire oceans, and literally freeze themselves solid, then walk away as if nothing happened. Scientists have measured, scanned, modeled, and argued about these abilities ...

How Ocean Conservation is Evolving: New Strategies to Save Marine Ecosystems

Annette Uy

The vast expanse of the world’s oceans is a source of wonder and a reservoir of resources pivotal for life on Earth. However, these marine ecosystems face unprecedented threats due to human activities. Overfishing, pollution, and climate change are just a few of the factors endangering marine biodiversity. In response, scientists, policymakers, and activists are ...

Mega-Iceberg A23a, Formerly the World's Largest, Turns Into Bright 'Blue Mush' as It Finally Dies After 40 Years at Sea

Mega-Iceberg A23a, Formerly the World’s Largest, Turns Into Bright ‘Blue Mush’ as It Finally Dies After 40 Years at Sea

Linnea H, BSc Sociology

There’s something oddly poetic about watching ice dissolve into blue pools thousands of miles from where it formed. For nearly four decades, the massive iceberg A23a has been a frozen monument drifting through the Southern Ocean, surviving longer than most icebergs ever dream of. Now, satellite images show it’s finally succumbing to warmer waters in ...

Coral Secrets Revealed: Diver-Operated Microscope Captures Photosynthesis in Real Time

April Joy Jovita

A new diver-operated microscope is revolutionizing coral research by allowing scientists to observe photosynthesis and microalgae behavior directly in the ocean. Developed by UC San Diego’s Scripps Institution of Oceanography, the Benthic Underwater Microscope Imaging PAM (BUMP) offers unprecedented access to coral bleaching and how they respond to environmental stress. A Technological Leap for Coral ...

Sea Creatures With the Most Extreme Breath-Holding Abilities

Jan Otte

It is amazing that some animals can stay underwater for hours or even months without breathing, even though their bodies are not designed to do so. Fish get oxygen from water through their gills, but marine animals that breathe air need to make amazing changes to their bodies and behavior to live in the deep. ...
