An international team of scientists have for the first time discovered two 160-million-year-old giant cephalopod fossils with intact ink sacs that contain dried pigment similar to that of modern cuttlefish.

Cuttlefish have the most acute polarization vision yet found in any animal, researchers at the University of Bristol have discovered by showing them movies on a modified LCD computer screen to test their eyesight.

Team from MBL, West Point uses new imaging technology to 'see' camouflaged marine animals in the eyes of their predators.

Noise pollution in the oceans has been shown to cause physical and behavioral changes in marine life, especially in dolphins and whales, which rely on sound for daily activities.

In deep ocean waters, it's sometimes difficult to hide from predators -- that's why so many sea creatures have evolved extraordinary methods of disguise.
