April Flowers for redOrbit.com - Your Universe Online Though the vampire squid was first discovered about 100 years ago, and a dozen scientific papers have been published, marine biologists have not been able to find out what the creature eats. A new study, led by the Monterrey Bay Aquarium Research Institute (MBARI), shows that unlike its relatives the octopus and squid, which eat live prey, the vampire squid uses two thread-like filaments to capture bits of organic debris that sink...

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. The researchers, of which includes a professor from the University of Virginia, said the ancient brownish-black pigment, known as eumelanin, is widespread in the animal kingdom in squid ink, bird feathers and even human hair and skin. And because the fossilized pigment is so similar to...

First Fruitful, Then Futile: Ammonites Or The Boon And Bane Of Many Offspring

For 300 million years, they were the ultimate survivors. They successfully negotiated three mass extinctions, only to die out eventually at the end of the Cretaceous along with the dinosaurs: Ammonoids, or ammonites as they are also known, were marine cephalopods believed to be related to today's squid and nautiloids. Ammonoids changed their reproductive strategy early on in the course of evolution. However, what was once a successful initial strategy may well have proved to be a fatal...

Once thought to be only the realm of the blue-ringed octopus, researchers have now shown that all octopuses and cuttlefish, and some squid are venomous. The work indicates that they all share a common, ancient venomous ancestor and highlights new avenues for drug discovery. Conducted by scientists from the University of Melbourne, University of Brussels and Museum Victoria, the study was published in the Journal of Molecular Evolution. Dr Bryan Fry from the Department of Biochemistry at the...
