I, Octopus – Science Friday

With thousands of chemically-sensitive suckers, color-changing skin, and a brain that literally stretches when they eat, octopuses seem like aliens living in our oceans. Understanding their physical adaptations and ho...

Turning Oil Rigs Into Reefs

If an oil rig is done producing oil, should the oil company return the ecosystem to its natural state by removing the rig? What if the 40 year old rig's underwater structure is covered with thriving marine life? T...

Live Stream: NOAA’s Okeanos Explorer in the Mariana Trench

While exploring the Mariana Trench -- the deepest part of our planet's oceans -- on April 24, 2016, researchers aboard the National Oceanic and Atmospheric Administration (NOAA)'s Okeanos Explorer saw a bioluminescent...

Why Do Deep Sea Creatures Look So Scary?

Why Do Deep Sea Creatures Look So Scary? Anna Rothschild of Gross Science explains how different it is at the bottom of the sea: Food can be scarce, there's tremendous ocean pressure, and it's dark. These environmenta...

Discovered! A “glowing” biofluorescent hawksbill sea turtle

You're on a night dive in the Solomon Islands to film biofluorescence in small sharks and corals. Your underwater camera system includes a blue light and a yellow filter that blocks out blue light, allowing you to see...

How Do Sharks and Rays Use Electricity to Find Hidden Prey?

Imagine if you had six traditional senses instead of five: Sound, sight, touch, smell, taste and... What might you pick? Echolocation? Magnetoreception? How about electroreception? Sharks, rays, skates and sawfish...

How do jellyfish sting?

Have you ever been stung by a jellyfish? From the huge Lion's mane jellyfish to tiny jellyfish larvae, jellies (which aren't actually fish) can accidentally sting ocean swimmers with their built-in defensive mechanism...

The stoplight loosejaw, the marlin, & Extreme Life of the Sea

Challenging environments can help create some of the most marvelous evolutionary solutions. Two examples: The stoplight loosejaw and the marlin. The Stoplight Loosejaw is a small, deep sea dragonfish that has an "i...

Divers may have discovered the largest squid egg mass ever seen

A group of divers discovered a "car-sized ball of squid eggs" at 22 meters (72 feet) deep off the coast of Turkey. From RR Helm at Deep Sea News, who has a lot of excellent information about the find: Lutfu Tanrio...

Studying the deep sea octopus Opisthoteuthis “Adorabilis”

From Science Friday's The Macroscope, Post Doctoral Researcher Stephanie Bush of the Monterey Bay Aquarium Research Institute (MBARI) introduces us to a tiny Opisthoteuthis deep-sea octopus, a creature that's in the s...

ROV footage of deep sea creatures from the coast of Puerto Rico

Real-time science collaboration is much easier thanks to today's streaming video technology. During dives made by a remotely operated vehicle (ROV) off the coast of Puerto Rico, a team of National Oceanic and Atmosphe...

From Drifter to Dynamo: The Story of Plankton – Deep Look

Mind-blowing fact: A massive group of single-celled algae called diatoms are considered champions of photosynthesis. Why? Diatoms are responsible for an estimated 20% to 40% -- maybe even 60% -- of the Earth's oxygen....

Ocean sponges have incredible filtering power

Ocean sponges are fascinating multi-cellular animals that don't walk or swim. They eat by filter-feeding, straining the water around them to capture organic debris particles and microscopic life forms. How powerfu...

ScienceTake: A Surprising Appetite for Dead Jellyfish

Marine scientists previously suspected that dead jellyfish were not a preferred choice of food for ocean floor scavengers, but a recently-recorded test using Helmet and Lion’s Mane jellyfish has prompted a rethinking ...

Tagging Tiny Turtle Hatchlings – ScienceTake

When sea turtle hatchlings emerge from their sand-covered eggs and scurry quickly toward the ocean, we know that, if they're lucky enough to avoid predators, they're helped forward on their journeys by the ocean curre...

Pygmy Seahorses: Masters of vibrantly-colored coral camouflage

The vibrant colors of thumbnail-sized Pygmy Seahorses have always been aligned with the brilliant oranges or purples of the Gorgonian sea fan corals that they're found camouflaged with, but until biologists at San Fra...

Sea cucumbers are underwater vacuum cleaners
