The reef manta ray (Mobula alfredi) is a tough swimmer. They can travel hundreds of kilometers to feed themselves. The longest recorded movement for an individual reef manta ray was 1,150km, observed in eastern Australia.
Humans have long been fascinated by organisms that can produce light. Aristotle, who was a scientist as well as a philosopher, wrote the first detailed descriptions of what he called "cold light" more than 2,000 years ago. ...
New research by Swansea University and the University of Zurich has found that sharks retained high levels of functional diversity for most of the last 66 million years, before steadily declining over the last 10 million ...
The most advanced molecular techniques contribute significantly to the identification of endangered sharks, rays and skates, collectively known as elasmobranchs, and are therefore fundamental to the enforcement of the laws ...
The deep sea is the largest living space on Earth, but many of the animals and habitats far beneath the ocean's surface remain shrouded in mystery. MBARI's advanced underwater robots, including remotely operated vehicles ...
Juvenile social play predicts adult reproductive success in male bottlenose dolphins, a new study has found.
Shark finning—the practice of removing the fins from a captured shark and discarding the rest, often still alive, back into the ocean—is banned in many countries due to its inhumane and unsustainable nature. However, ...
Using a novel genetic clock, a team of researchers from Kiel, London, Oldenburg, and Davis, California, has determined the age of a large marine plant clone for the first time. This seagrass clone from the Baltic Sea dates ...
When scientists want to study the long-distance movement of marine animals, they will instrument them with a small device called an acoustic transmitter—or tag—which emits unique signals or "pings." These signals are ...
A tiger shark has surprised Australian scientists on an ocean research trip by regurgitating a spiky land-loving echidna in front of them.
