The tip of the squid’s beak is 100 times stiffer than its base. Zok and his colleagues have recently uncovered the mystery to the squid’s beak.Īccording to researchers the key is that the hardness of the squid’s beak is graded. The blade would cut through the Jell-o at least as much as the targeted object”. “You can imagine the problems you’d encounter if you attached a knife blade to a block of Jell-O and tried to use that blade for cutting. “Here you have a ‘cutting tool’ that’s extremely hard and stiff at its tip and is attached to a material - the muscular buccal mass - that has the consistency of Jell-O,” explains Frank Zok, professor and associate chair of the Department of Materials at the University of California of Santa Barbara. But how does a squid, whose body is soft and supple, have a beak that is considered one of the hardest organic materials in natures? Scientists have long pondered this question. Scientists can tell the diet of a whale by the variety of beaks left behind, sometimes numbering in the thousands. When scientists dissect the stomachs of sperm whales, they find the super-hard beaks of squids, the only part of them that is indigestible.
