"How the mantis shrimp uses a boxer's technique to protect itself"


The mantis shrimp is known as the ocean's heavy‐hitter. It has a hammer-like club that moves with the speed of a .22 calibre bullet and strikes with the force of 1,500 newtons ‐ enough to smash the glass of an aquarium ‐ that pulverises its prey. Until now, scientists have not known how the animal does this without injuring itself, but a new study shows that the hammer is bound with unique structure that protects it rather in the way binding protects a boxer's hands...

"Researchers Developing Super–Strong Materials Thanks to a 3D Printer and the Mantis Shrimp"


The rainbow–colored mantis shrimp is gorgeous to look at – to humans, anyway. To its fellow crustaceans, it’s a purple–eyed horror. The mantis shrimp is a brutal killer that dispatches its prey by beating it to death with a fist–like appendage that can hammer out blows at speeds of 10,000g – the velocity of a .22 caliber bullet. It may be a crab’s worst nightmare, but that appendage, called a dactyl club, is currently of great interest to researchers at Purdue University and the University of California, Riverside... read article

"The Secret of the Glass–Cracking Mantis Shrimp"


Mantis shrimp may reach only about 6 inches in length, but they pack quite a punch with their "clubs," appendages they slam down on prey with incredible velocity and power. These clubs reach speeds equivalent to that of a bullet fired from a gun, and their strike can break aquarium glass and split open human thumbs. This movement also creates an imploding underwater air bubble that, ever so briefly, reaches a temperature greater than the surface of the sun... read article

"Tiny Shrimp’s Powerful Punch Inspires a New Kind of Human Helmet"


Mantis shrimp pack a famously big punch. The same engineering that keeps their hammer–like claws intact could shape a new generation of human body armor.

The mantis shrimp has gained notoriety in recent years after being featured on popular internet sites such as YouTube or the webcomic, "The Oatmeal." This week, however, scientists have released a study that suggests the mantis shrimp may soon become better known for the body armor – including a helmet – it inspires... read article

"Scientists Crack Mystery of Shrimp Packing Such a Punch it can Split Your Thumb"


In tropical shallows the world over, a peculiar sort of creature scurries along the sea floor, unassuming except for the fact that it sports one of the most powerful biological appendages known to science – its spring–loaded claws. The mantis shrimp, which typically grows no more than 6 inches in length, is an aggressive, burrowing crustacean that looks a bit like a crayfish dipped in neon spray paint. Fishermen call the animals "thumb–splitters" – at least one man has had a finger amputated after a mantis shrimp strike – and a blow from the crustacean’s truncheon can crack a pane of stock aquarium glass... read article

"Ultra–strong 3D printed material inspired by natural herringbone pattern on mantis shrimp"


Researchers at the University of California, Riverside and Purdue University have used the mantis shrimp as inspiration for a new 3D printed material. The crustacean's club–like appendage, used to beat prey, consists of an unusual herringbone pattern, which the researchers synthetically replicated.

When looking for ways to strengthen a material, nature often provides the best answers. Airbus recently found that they could copy cell and bone structures to make a 3D printed airplane cabin partition, while researchers at Purdue University last year had a "Eureka!" moment with honeycombs, whose patterns were mimicked to make a super–strong 3D printed material for football helmets... read article

Convergent Evolution to Engineering: Multiscale Structures and Mechanics in Damage Tolerant Functional Bio–composite and Biomimetic Materials


Professor David Kisailus and a team of researchers from several universities across the country received a $7.5 million from the Department of Defense’s Multidisciplinary University Research Initiative Program (MURI) to study design structures of several organisms and develop tough materials based on those structures.
 
This MURI program is designed to uncover fundamental design rules and develop simple and basic scientific foundations for the predictable design of bio–inspired materials that are lightweight, tough and strong. An integrated team of materials scientists, biologists, and engineers will elucidate hundreds of millions of years of evolutionary changes in plant and animal species to understand structures and physical mechanisms that underpin the micro– and nanomechanics of tough, strong structures. We will incorporate comparative analyses of multiscale structures to pinpoint which design principles are evolutionarily unique solutions and which have arisen convergently; when more than one evolutionary path arrives at the same solution, we have a good indication that it is the best solution. We will also extend these structural themes to incorporate multifunctionality, for example, sensory and self–healing elements. In addition, we look to take small–scale mimicry and extend it to large scale processing. Through this process, we will derive new experimental characterization, modeling and biomimetic toolkits, which will be useful for other programs within the DOD and beyond.
 
The overall objectives of the program are to: Understand the effect of material components (organic, inorganic and porosity) on composites properties (density, stiffness and toughness). Uncover the effect of gradients and interfacial components on mechanical properties. Reveal the effect of length scale on mechanical properties. Orchestrate commonalities between design features within varied classes of organisms.

The Stomatopod Dactyl Club: A Formidable Damage–Tolerant Biological Hammer


Congratulations to members of the Kisailus lab for publishing in the June 8 edition of Science, "Lightweight Impact–Resistant Composite Materials: Lessons from Mantis Shrimp" Kisailus and James C. Weaver, who worked with Kisailus as a post–doctoral scholar and is now at Harvard University, began work on the mantis shrimp when Kisailus arrived at UC Riverside in 2007. They were later joined at UC Riverside by Garrett W. Milliron, a Ph.D. student, and Steven Herrera, an undergraduate student. Kisailus and Pablo Zavattieri, of Purdue University, one of the co–authors of Science paper, just received additional $590,000 in funding from the Air Force Office of Scientific Research to continue work on the stomatopod. They want to further understand the structure of club and continue work designing materials inspired by that structure. Additionally, this work has received an enormous amount of press coverage including articles in the New York Times and Chemical and Engineering News
