A 3-foot-long mammoth tusk hidden on the ocean floor could offer clues about the ancient creatures

Members of the science team at the Monterey Bay Aquarium Research Institute observe the mammoth tusk.Darrin Schultz © 2021 MBARI Scientists discovered a 3-foot-long mammoth tusk roughly 10,000 feet below the ocean's surface. The deep sea is ideal for preserving remains, though mammoth fossils rarely wind up there. The tusk belongs to a young female mammoth. Scientists are using it for clues about how she lived. To the untrained eye, it may have looked like a giant wood log. In reality, sc...

Glow-in-the-dark milky seas of maritime lore really exist – satellite proves it

For centuries, sailors have been reporting strange encounters like the one below. “The whole appearance of the ocean was like a plain covered with snow. There was scarce a cloud in the heavens, yet the sky … appeared as black as if a storm was raging. The scene was one of awful grandeur, the sea having turned to phosphorus, and the heavens being hung in blackness, and the stars going out, seemed to indicate that all nature was preparing for that last grand conflagration which we are taught to ...

Toxic Algae Has Sent Hundreds of Americans to the ER Since 2017, CDC Study Finds

Toxic algae blooms have sent over 300 Americans to the emergency room in recent years, new research from the Centers for Disease Control and Prevention has found. Researchers reviewed ER visits related to algae bloom exposure across the country between 2017 and 2019, and they warn that doctors will need to be on the…Read more...

Scientists Are Racing to Save These Sea Stars From Extinction

Since 2013, a disease exacerbated by overheating oceans has been decimating sea star populations, especially those of one particularly striking variety: sunflower sea stars. Over the course of three years, the illness killed off nearly 91% of the sunflower species’ global population. Now, scientists are fighting to…Read more...

How to fool a shark using magnets

It's long been suspected that sharks navigate the oceans using Earth's magnetic field. Sharks are, however, difficult to experiment with.Using magnetism, marine biologists figured out a clever way to fool sharks into thinking they're somewhere that they're not.For some time, scientists have suspected that sharks belong among the growing number of animals known to navigate using Earth's magnetic field. Testing anything with a shark, though, requires some care. "The reason this question has been ...

Colorful Photos Reveal the Secrets of Australia’s Twilight Zone Coral Gardens

In the depths of the ocean off the northwest Australian coast lie vast, mysterious ecosystems. Until recently, they were completely undocumented by scientists. A team of researchers changed that in mid-April, though, after they boarded an oceanic research vessel known as the R/V Falkor. Equipped with advanced robotic…Read more...

Grunion are running — and if you’re lucky, you may see the Southern California phenomenon

All eyes stared out toward the dark ocean, waiting for movement on the wet sand as each wave receded, hoping little wiggly sea creatures would suddenly show. Birds lined the waterline, anxiously waiting for the flopping fish to land on the sand so they could feast. People watched just as eagerly under the stars, hopeful as the two-hour window for the expected grunion run began. Grunion runs should be happening at local beaches this week, a nighttime phenomenon unique to Southern California where...

New research reveals why some octopuses punch fish

Octopuses are part of multispecific collaborative hunting groups with bottom-feeding fish. New research shows octopuses defending their territory by punching fish. The team believes this research helps reveal underlying game structures in the deep sea. The psychologist William James noted that consciousness did not arrive in the universe fully formed. Phenomena like perception and memory are in no way limited to our own form of consciousness, though humans often pretend we're evolution's crown...

Scientists discover slug that can decapitate itself, grow new body

In a recent study, scientists observed two species of sea slug that were able to self-decapitate, survive for weeks without organs, and regenerate entirely new bodies.The study authors proposed that the slugs are able to survive as severed heads because of the unique way they obtain energy from algae.While other animals engage in self-amputation (known as autotomy) to avoid predators, the study authors suggested that sea slugs might shed their bodies to avoid dying from parasites. For almost ev...

Cephalopod aces 'marshmallow test' designed for eager children

Scientists recently ran the Stanford marshmallow experiment on cuttlefish and found they were pretty good at it. The test subjects could wait up to two minutes for a better tasting treat. The study suggests cuttlefish are smarter than you think but isn't the final word on how bright they are. The Stanford marshmallow test, an experiment asking kids to hold off on eating one marshmallow for 15 minutes in exchange for two as a reward, was introduced in 1972 by psychologist Walter Mischel. The st...

Unusual creatures uncovered beneath an Antarctic ice shelf

A new study details the discovery of sessile organisms living under the Antarctic's Filchner-Ronne Ice Shelf.In recent years, scientists have discovered more creatures living in environments once thought inhospitable to life. It's currently unknown how these new organisms find food in such an environment, nor how plentiful they are beneath the continent's ice-blanketed coastlines. Life finds a way. That way may be uncomfortable, brimming with struggle, and demand an unsightly appendage or two, ...

Noise pollution is threatening life in the 'Anthropocene ocean'

The new paper notes three major factors that have changed the ocean soundscape: human activity, climate change, and "massive declines in the abundance of sound-producing animals."Noise pollution threatens marine animals because many rely on sound to communicate with each other and sense predators and prey. The paper noted several solutions for decreasing human-caused noise pollution, including floating wind turbines and quieter boat propellers. From shrimp to whales, marine animals use sound to...

Marine biologists discover 4 new types of photoreceptor

The ocean is full of simple single-celled organisms that somehow follow day-night cycles.Researchers have just discovered four new groups of photoreceptors that help the organisms detect light.The photoreceptors may find use in studies of the human brain. When it comes to senses like ours, tiny single-celled organisms floating in the ocean don't have much going on. And yet, as Sacha Coesel, the lead author of a new study from University of Washington researchers, puts it: "If you look in the oc...

Australian Robots Are Exploring to the Deep Sea to Study Marine Snow

New Blue Whale Population Discovered After Scientists Hear Unknown Song

Do you ever hear a new song and realize it’s unlike anything you’ve heard before? I felt that a few times this year, mostly with Phoebe Bridgers and Polo G. It happened to scientists recently, too. But it wasn’t a new singer or rapper they discovered; it’s a new population of whales.Read more...

NOAA discovers a new, beautifully weird sea creature

Gorgeous simplicity characterizes the comb jelly recently discovered by National Oceanic and Atmospheric Administration Fisheries.The small denizen of the deep was spotted three times beneath the waters off Puerto Rico.Though it's unusual to formally identify an animal strictly based on video observations, the quality of NOAA's video made it possible in a case where there's no better alternative. Usually, when scientists announce the discovery of a previously unknown animal, they have a specime...

Explorers revisit a whale carcass one year later

You may recall that last year, Nautilus EV discovered a whale fall being actively scavenged. One year later they returned to see what happens a year after a baleen whale dies and sinks to the bottom of the sea. Whale falls are of great interest to scientists because they have not been easy to document before the advent of undersea craft. — Read the rest

12 Sea Creatures That Look Extremely Fake
