The top predator prowling the seas during the age of the dinosaurs 100 million years ago may have been the octopus.
RIKEN researchers have determined the molecular structure of an enzyme that occurs in fish. This could shed light on molecular processes in a wide range of marine organisms. The work is published in the Journal of Biological ...
Biologists have long puzzled over why organisms with similar numbers of protein-coding genes can differ so dramatically in nervous system complexity. New research points to a potential link between the expanding diversity ...
Biological invasions occur when organisms such as animals and plants are introduced by people to regions of the world where they do not naturally occur. In these new locations, these organisms are referred to as "alien species."
Today's octopuses are intelligent, remarkably flexible animals that lurk in reefs, hide in crevices, or drift through the deep sea. But new research suggests that their earliest relatives may have played a far more predatory ...
"A rose by any other name would smell as sweet," said Juliet Capulet in William Shakespeare's famous play. And the same is presumably true for mollusks, albeit with different odors. When you think about the scientific names ...
Happy Saturday! This week, researchers reported on the familiar phenomenon of speeding away from a slower-driving car only to have it catch up at the next traffic light—they've named it Voorhees law, after the well-known ...
For mating male octopuses, one limb is more important than all others. That is the third right arm or hectocotylus, which is used to transfer sperm to the female because the penis cannot do it directly. Losing the limb can ...
A famous 300-million-year-old fossil that was thought to be the world's oldest octopus—even featuring in the Guinness Book of Records—has turned out to be something else altogether. In what amounts to a case of mistaken identity, ...
