Hot Bodies Reveal Where Pacific Bluefin Tuna Eat

Scientists have developed a new way to measure how and when ocean predators consume prey, and they’ve used it to identify the Pacific bluefin’s favorite hot spots. The findings could help design better conservation policies to help a species in steep decline. Pacific bluefin tuna are superbly streamlined, bullet-shaped fish, with powerful swimming muscles capable […]

This Cave May Hold Clues To Future Climate Change

A period of abrupt climate change 12,000 years ago occurred rapidly in northern latitudes but much more gradually in equatorial regions, report researchers. The discovery could prove important for understanding and responding to future climate change. The research focuses on the Younger Dryas, a cooling period that started when the North Atlantic Current, an ocean […]

Climate Change Will Reshuffle Marine Life

Marine species are relocating, generally toward the poles, to find water temperatures that better suit them, scientists say. By the end of the century, they predict warmer oceans will result in significant global redistribution of marine life. This in turn will increase biodiversity in many areas or lead to extinctions in others, all while creating […]

Rare Slimy Nautilus Seen For First Time In 30 years

Earlier this month, biologist Peter Ward returned from visiting the South Pacific with news that he had come across an old friend he hadn’t seen in more than three decades. It happened to be a creature that scientists think may be one of the rarest animals in the world. Allonautilus scrobiculatus is a species of […]
