Two researchers from Trinity College Dublin are among a four-strong team of principal investigators spearheading a new €10.4 million project funded by the European Research Council (ERC) to assess the importance of marine life to human societies during the last two millennia, with a focus on understanding the consequences of […]

When it comes to hitching a ride, whale-surfing remoras are perfectly at home latching onto the largest creatures on the planet. “From static photos, it’s easy to […]

A new study shows that the body size of the iconic gigantic Megalodon or megatooth shark, about 50 feet (15 meters) in length, is indeed anomalously large compared to body sizes of its relatives. Formally called Otodus megalodon, the fossil shark that lived nearly worldwide roughly 15-3.6 million years ago is […]

The reef at North Rock, Bermuda, similar to the reef (Sea Venture Shoals) where coral fragments were collected for this study. Credit: Stacy Peltier New research shows that pulses of cooler deep water reduced heat stress responses in corals. The risk of severe coral bleaching—a condition in which corals lose […]

Tea There Are Many More Angelfishes in the Sea Why do some fish species form hybrids while others don’t? In attempting to answer this question, new research has uncovered that angelfish are the chief […]

Nova Southeastern University researchers lead team studying smooth hammerhead sharks. They are some of the most iconic and unique-looking creatures in our oceans. While some may think they look a bit “odd,” one thing researchers agree on is that little is known about hammerhead sharks. Many of the 10 hammerhead […]

Using state-of-the-art robotics, a research team from the University of Konstanz, Science of Intelligence, and the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) shows that animals’ speed is fundamental for collective behavioral patterns, and that ultimately it is the faster individuals that have the strongest influence on group-level […]

ANIMATION Sharks’ non-bony skeletons were thought to be the template before bony internal skeletons evolved, but a new fossil discovery suggests otherwise. The discovery of a 410-million-year-old fish fossil with a bony skull suggests the lighter skeletons of sharks may have evolved from bony ancestors, rather than the other way […]
