The new Humboldt data is about to be published in a special issue on oceanic squid in the journal Deep Sea Research II. The water is a surprisingly crucial element too. The Humboldt squid’s beak is two inches long and incredibly hard (difficult to dent or scratch), stiff (difficult to bend out of shape) and tough (resistant to fractures). Behaviour Upon reaching striking distance, they open their eight swimming and grasping arms, and extend two long tentacles covered in sharp 'teeth', grabbing their prey and pulling it back towards a parrot-like b… Miserez found that the soft base is mostly water (70%) and chitin (25%). When Miserez dissolved all the components away aside from chitin, he found that this polymer forms an intricate network of fibres, just 30 nanometres thick. Miserez also tantalisingly suggests that Dopa-rich proteins tend to repel water, so their presence at the beak’s tip during development could help to set up the chemical gradient by driving water away to the base.
