Like Humans, Sperm Whales May Be Speaking In Different Regional Dialects
Scientists have found that sperm whales in the eastern Mediterranean have developed a faster, distinct vocal dialect compared to whales in the western Mediterranean, highlighting how animal communication and culture can evolve over generations.

Cocaine Unlocks 'Wanderlust' Spirit In Salmon, Study Finds
A new study shows that cocaine and its main byproduct alter salmon movement and dispersal behaviour.

Scientists Discover Clicking Sounds in Rig Sharks for the First Time
Sharks were long thought to be silent, but a surprising new study reveals that rig sharks can make clicking sounds when handled. Evolutionary biologist Carolin Nieder first discovered the clicks by accident during lab tests. These sounds—likely produced by snapping their flat teeth—occurred most often during initial handling, suggesting a stres...

Cuttlefish May Communicate Using Tentacle Waves, Study Finds
Cuttlefish are known to use more than color-changing and posture to communicate — new research suggests they wave their tentacles to send signals. Scientists at École Normale Supérieure observed four distinct wave patterns and found cuttlefish respond both visually and through water vibrations. With plans to use AI and robotics to decode these ...

Study Finds Grey Seals Can Track Blood Oxygen to Prevent Drowning
A study has revealed that grey seals can monitor their blood oxygen levels to determine when they need to surface for air. Researchers tested seals in controlled environments, exposing them to different oxygen and carbon dioxide levels. The findings confirmed that higher oxygen led to longer dives, while reduced oxygen shortened them. Surprisingly,...

Pregnant Great White Shark Killed in Queensland to Aid in Scientific Research
An 18-foot pregnant great white shark was killed on a Queensland drumline in August. This marks the largest white shark caught by the state’s Shark Control Program since its inception in 1962. While her death is a conservation setback, researchers are using samples from her body to study the species’ biology, reproductive patterns, and environm...

Solitary Dolphin in Baltic Sea Talks to Himself, Researchers Think it's a Sign of Loneliness
A bottlenose dolphin, known as Delle, has been observed in the Baltic Sea making thousands of vocalisations. The solitary dolphin’s sounds, including whistles and clicks, suggest it may be lonely and trying to communicate. Despite being in an area outside the usual range for these dolphins, no other dolphins were nearby. Researchers are exploring...

Record-Breaking Marine Predation Event Provides Insights into Ocean Ecosystems
In a groundbreaking observation, scientists have recorded the largest marine predation event ever documented, offering unprecedented insights into ocean ecosystem dynamics. Using advanced sonar technology, researchers tracked interactions between capelin, a small forage fish, and their primary predator, cod, as part of a massive, coordinated predat...

Panda-Coloured Amphipod Confirmed as New Species, Discovered Along Japan’s Coastline
A newly discovered amphipod species, Melita panda, has been confirmed as a unique species in Japan’s coastal waters. This crustacean, named for its black-and-white coloring resembling that of a panda, was originally found in the 1990s but has only now been recognized as a distinct species. Researchers at Hiroshima University conducted thorough ge...

Researchers Create Innovative 3D Maps to Understand Octopus Arm Systems
Researchers at San Francisco State University have developed advanced three-dimensional maps of octopus arms, revealing their complex nervous systems. Led by Robyn Crook, the team used innovative imaging techniques to understand how octopus arms can function almost independently from the brain. These discoveries highlight the unique neuronal organi...

Scientists Discover Ghostly 'Spookfish' That Prowls Pacific Ocean Floor
Scientists in New Zealand said Tuesday they have discovered a new species of "ghost shark", a type of fish that prowls the Pacific Ocean floor hunting prey more than a mile down.

Porbeagle Shark Predation Documented: Great White Likely Behind Attack
Scientists have documented the first case of an adult porbeagle shark being predated upon by a great white shark. In 2020, a porbeagle shark fitted with tracking devices went missing, and the recovered data indicated that the shark was likely eaten by a larger predator. Analysis of temperature data from the tag pointed to a great white shark, thoug...

"We Saw Skeletons": Mysterious Sea Urchin Deaths Threaten Red Sea Corals
The Red Sea's spectacular coral reefs face a new threat, marine biologists warn -- the mass death of sea urchins that may be caused by a mystery disease.
