The nutritional biology of common octopus paralarvae is a rapidly advancing field that integrates physiology, biochemistry and molecular biology. Paralarvae, representing the early, planktonic stage ...

The octopus is one of the most extreme animals on Earth. Its biology looks more like science fiction than natural evolution. From decentralized brains to color-changing skin and near-human ...

Octopuses possess a unique three-heart system that allows them to survive temporary cardiac pauses, a feat impossible for most animals. This, combined with their efficient haemocyanin oxygen carrier ...
