170O POUND GREAT WHITE SHARK TRACKED - FLORIDA TO NORTH CAROLINA : HE'S NAMED "CONTENDER"

CBS NEWS : 1700 POUND SHARK TRACKED OFF COAST OF NORTH CAROLINA 

Excerpt:

Sharks don't ping every day. Their movements are tracked by devices attached to their dorsal fins. The trackers can't transmit through water, OCEARCH senior data scientist John Tyminski said in a video published by the organization. To accurately confirm a shark's location, the tracker must break the surface while an Argos satellite is above. The satellites are only in a given spot for about 13 minutes. During that time, the tracker must send multiple messages for a location to be confirmed.

FIRST SHARK OFF ANTARCTICA CAUGHT ON CAMERA - WHY IT MATTERS

FORBES : ANTARCTICAS FIRST SHARK CAUGHT ON CAMERA 

Excerpt: Sharks have survived mass extinctions, shifting continents and dramatic climate swings for more than 400 million years. They patrol coral reefs, cruise open oceans, call kelp forests home and rule the deep sea. And while Greenland sharks (Somniosus microcephalus) are known to rule the icy, dark waters of the Arctic Ocean, the Antarctic landscape has long been barren of this predator. The Southern Ocean is frigid, remote and punishingly cold, with temperatures dipping below zero. Which is why new footage captured near the South Shetland Islands is so remarkable: for the first time, a shark has been recorded on video in the Southern Ocean itself.

TOM GRUBER FIRST FOOTAGE OF HAWAIIAN DAY OCTOPUS WHO RECOGNIZED HERSELF ?! DO YOU AGREE?

I think Octopuses might be the most intelligent of sea creatures, other than the whales.  In this video, Tom  Gruber, the inventor of Siri, filmed one that saw itself in a mirror.  To be honest, I think the octopus saw another octopus.  DO YOU THINK IT KNEW IT WAS LOOKING AT ITSELF?

CARNIVOROUS DEATH BALL SPONGES! ZOBIE WORMS!?

Carnivorous!  OCEAN CENSUS ORG

Excerpt:

Its spherical form is covered in tiny hooks that trap prey, a clear contrast to the gentle, passive, filter-feeding undertaken by most sponges. ‘Zombie worms’ (Osedax sp.) were also observed. Although not thought to be new to science, these worms have no mouth or gut and rely on symbiotic bacteria to break down fats inside the bones of whales and other large vertebrates.

 

SMITHSONIAN : NEW SPECIES IN SOUTHERN OCEAN

RARE SIGHTING OF GIANT PHANTOM JELLY FISH OFF THE COAST OF ARGENTINA

OOOH this BBC website has video of the swimming phantom!

BBC NEWS : RARE SIGNTING PHANTOM JELLY OFF ARGENTINA

Excerpt:

A rare phantom jellyfish has been spotted by scientists exploring the deep sea near Argentina.

Stygiomedusa gigantea, more commonly known as the giant phantom jellyfish, was filmed 250 metres below the surface in the South Atlantic Ocean.

Scientists from the Schmidt Ocean Institute documented the creature, which can grow up to 1m (3.3ft) in diameter, with their arms reaching up to 10m (33ft) long.

Their four arms, which look like long pink ribbons, are not stinging tentacles. Instead the jellyfish use them to catch their prey of fish and plankton, according to the institute.

The team also discovered 28 potential new species including corals, sea urchins, and sea anemones.

ORCAS HAVE BEEN SINKING BOATS

It's true... there have been a number of reports.


DIVE MAGAZINE : ORCAS SINK BOAT - PORTUGAL


OUTSIDE ONLIE : WE SAILED THROUGH ORCA ALLEY - BOATS RAMMED -SINKING


Excerpt: Along the Iberian Peninsula, where the North Atlantic collides with the rugged coastlines of Spain and Portugal before pinching into the Mediterranean Sea, an endangered subpopulation of orcas has developed the unfortunate habit of ramming into sailboats. The powerful animals target the rudders, often breaking them and destroying or disabling a boat’s steering. Such force can sometimes also damage a boat’s hull and cause a leak.

Orcas, also called killer whales (Orcinus orca), are known for their prowess as marine predators, and they’re intelligent and highly social. Across their global range, they’re unusually flexible in what they eat, how they hunt, and where they call home. Among their many talents, they’re masters of surprise.

PANAMA : OCEAN WATERS DID NOT RISE SEASONALLY FOR THE FIRST TIME IN 40 YEARS : TERRIBLE CONCERN THAT OCEAN SYSTEM IS COLLAPSING

NEWSROOM PANAMA : FOR THE FIRST TIME IN 40 YEARS

Excerpt: For over 40 years, seasonal upwelling in the Gulf of Panama has followed a consistent pattern. Between the end of the calendar year and early spring, trade winds from the north push surface waters offshore, drawing cooler, deeper water upward. The process delivers nutrients that stimulate phytoplankton growth, forming the foundation of the marine food web. .................

In early 2025, that system failed. No cold water rose to the surface. No spike in surface chlorophyll was recorded. Ocean surface temperatures remained elevated through the season. According to data collected by scientists aboard the S/Y Eugen Seibold, a research vessel jointly operated by the Smithsonian Tropical Research Institute and the Max Planck Institute, the vertical movement of water that characterizes the upwelling was entirely absent. The study documenting the event, published in Proceedings of the National Academy of Sciences, confirms it as the first complete suppression of the upwelling in the observational record. Researchers noted that this shift eliminated a key stabilizing mechanism in the region’s marine ecosystem and exposed vulnerabilities in the broader ocean-climate system.

Winds Weaken, With Cascading Effects

At the center of the disruption was a collapse in atmospheric drivers. The northern trade winds, normally responsible for triggering the upwelling process, were significantly weaker in early 2025. As a result, surface waters remained in place, and the temperature differential needed to initiate vertical mixing did not materialize. The absence of cooler waters had immediate ecological effects. Without an influx of nutrients, phytoplankton production declined sharply. Satellite observations confirmed reduced chlorophyll-a concentrations throughout the Gulf of Panama during the period when biological productivity typically peaks.

OCNONPROFITCENTRAL : OCEAN DEFENDERS ALLIANCE

This looks like a great one!

Excerpt: In 23 years, ODA has performed just under 600 ocean cleanups in 7 different counties of California and Hawai'i. The debris that has been removed from harm's way includes:

Plastics: over 84 tons (168,000 pounds)
Traps: 540
Trap lines that entangle whales: 51,000 feet
Fishing line: 293,000 feet
Nets: 49,000 pounds
Misc Debris: 139,000 pounds
Lead fishing weights: 11,500 pounds

And so much more! Marine wildlife and their habitats are safer without this hazardous debris.

************

Ocean Defenders Alliance (ODA) began protecting California's ocean ecosystems and wildlife in 2000. We are the longest running nonprofit focused solely on removal of dangerous man-made fishing gear from the coastal waters of California.  Since then, and because of the help of our many wonderful volunteers, we have removed vast amounts of trap-line and net that too often entangle whales, dolphins, and sea lions. We have also recovered hundreds of abandoned lobster traps and many tons of other debris that was threatening marine life. The result for sea life is simple: ODA's work has saved hundreds of thousands of animals from unnecessary and horrific death (most often drowning or starvation).  The world's oceans are in serious decline, primarily due to human abuse and neglect--but there is cause for hope! Working together with respect and focus, we will increase our already positive impact.  Please help us ensure healthy oceans for future generations. The time to act is NOW! Come join us!

PREHISTORIC SHELL TRUMPETS STILL MAKE SOUND!

DAILY MAIL : SCIENCE : PREHISTORIC SHELL TRUMPETS 

Excerpts: Amazingly, eight of the instruments still worked perfectly, with the loudest toot reaching 111.5 decibels - as loud as a powerful car horn or trombone.

Researchers believe that these trumpets would have been used as an ancient form of communication technology, with simple codes shared between communities.

These blasts could easily travel the three to six miles (five to 10 km) between the Stone Age villages where the horns were discovered.

They could have been used to communicate between different settlements, warning of attacks or coordinating harvest times.

Others, found deep within abandoned mines, might have been used to send messages through the underground darkness.

HUNDREDS OF PINK DOLPHINS FOUND DEAD IN BRAZIL'S LAKE TEFE : THEY BOILED IN HEAT WAVE WATER HOTTER THAN A JACUZZI

CBS : DOLPHINS DEAD IN WATER HOTTER THAN JACUZZI BRAZIL LAKE TEFE 

Excerpts: 

Officials from the World Wildlife Fund Brazil said 153 dolphins were found dead the week of Sept. 23, 2023, including 130 pink dolphins, and 23 tucuxi dolphins. Both are listed as endangered on the IUCN Red List and the latter of which are considered "the guardians of rivers and a symbol of good luck," according to RiverDolphins.org.

"The climate emergency is here"

What made it even more remarkable, said Fleischmann, was that the same temperature was found not just at the surface but throughout the two-meter-deep water column.

Using computer modeling, the team identified four key drivers: strong solar heating, shallow waters, low wind speeds, and high turbidity — a measure of water haziness.

These factors reinforce one another. Shallowness increases turbidity, which traps more heat, while low wind carries less heat away, leaving the water more exposed to clear skies and intense sunlight.

Another stressor for aquatic life was the large swing between highs and lows, with the peak of 41C in Tefe followed by a nighttime low of 27C.

BLUE WHALES GONE SILENT?! CLIMATE CHANGE? ALL ENERGY USED TO FIND ENOUGH FOOD - KRILL

THE WEEK : BLUE WHALES NOT SINGING -CLIMATE CHANGE

Excerpt: The study tracked over six years of acoustic monitoring in the central California Current Ecosystem. During those years, blue whale sounds decreased by approximately 40%.

"We don't hear them singing," John Ryan, a biological oceanographer at the Monterey Bay Aquarium Research Institute and the lead author of the study, said to National Geographic. They are "spending all their energy searching." There's "just not enough time left over" for singing, and that "tells us those years are incredibly stressful." It's like "trying to sing while you are starving,"

"When we have these really hot years and marine heat waves, it's more than just temperature," Kelly Benoit-Bird, a marine biologist at Monterey Bay Aquarium and co-author of the study, said to National Geographic. "The whole system changes, and we don't get the krill." So the animals that "rely only on krill are kind of out of luck." High ocean temperatures lead to algal blooms that can kill krill. And blue whales are "forced to forage over a much larger geographic area when krill populations become depleted," said Newsweek.

Marine heat waves are only going to get worse due to fossil fuel usage. Oceans act as the world's largest carbon sink, meaning they "already absorb more than 90% of the excess heat from climate change," said The Independent. There are "whole ecosystem consequences of these marine heat waves," said Benoit-Bird. If whales "can't find food and they can traverse the entire West Coast of North America, that's a really large-scale consequence."

LEAF SHAPED FANGS?! PACIFIC DISCOVERY LINKS UNPRECEDENTED FIND! GINKO BEAKED WHALES

Unprecedented!   OOOOH this is great!

UNION RAYO: GOODBYE TO DECADES OF ASSUMPTIONS : GINKO BEAKED WHALES

Excerpt: For the first time in history, a team of scientists managed to see, record and document the elusive ginkgo-toothed beaked whale (Mesoplodon ginkgodens) swimming in open sea, off the coast of Baja California, Mexico. And the best part is that with this encounter they also solved a mystery that had been puzzling experts for more than a decade, a mysterious acoustic signal, the famous BW43, that no one had managed to attribute to a specific species.

.... For the first time, a species known only from stranded remains was alive, recorded, confirmed!!! Now scientists can track this species without seeing it, just by listening to its signals in the ocean.

Battles, wounds and sharks

The ginkgo-toothed beaked whale has a distinctive feature and it is that the males develop two flat leaf-shaped teeth near the tip of the snout. They do not use them to eat, but to fight with other males for the females.

The photos show long scars, cuts, white lines, many battles on their backs. In addition, many had circular bite marks made by sharks called “cookie cutters”.
