By Henry Workman In the Atacama Desert near Caldera, Chile, fossils of 75 prehistoric whales were discovered amid a highway construction project. Estimated at more than 2 million years old but remarkably intact, the remains were found in an unusual cluster no less than 800 meters (or ½ mile) from the ocean. Theories are accumulating […]
By Henry Workman Research from New Zealand’s Massey University and Te Papa has produced footage revealing the hagfish’s one-of-a-kind defense mechanism. When threatened the creature will expel a mucus-like substance which interferes with the gill functioning of predators, causing them to gag and swim away. The study also yielded insight into the hagfish’s own predatory […]
By Henry Workman Marine Science Today Writer Between 245 and 90 million years ago a large, fish-like reptile called the ichthyosaur dominated the Mesozoic ocean at the top of the food chain. It’s unlikely that the ichthyosaur had any predators of its own, which makes a paleontological site in Nevada containing fossil remains of […]
By Henry Workman Marine Science Today Writer Species of jellyfish provide greater competition for more complex organisms than previously thought. Recent research published in Science reveals that in areas where plankton-feeding fish populations have dropped off, mostly due to overfishing, jellyfish that occupy a similar ecological niche have taken their places. The jellyfish populations have […]
By Henry Workman Marine Science Today Writer A virus-fighting substance known as squalamine is the subject of new research published in Proceedings of the National Academy of Sciences (PNAS). The compound was originally discovered in the liver of dogfish, where it plays an important role in protecting it, as well as some other species, from […]
