SUMMARY Mantis shrimp are renowned for their unusual method of breaking shells with brief, powerful strikes of their raptorial appendages. Due to the extreme speeds of these strikes underwater, cavitation occurs between their appendages and hard-shelled prey. Here we examine the magnitude and relative contribution of the impact and cavitation forces generated by the peacock mantis shrimp Odontodactylus scyllarus. We present the surprising finding that each strike generates two brief, high… 

The Consequences of Speed: Studies of Cavitation During the Mantis Shrimp Strike and the Control of Rapid Deceleration During Toad Landing

It is found that in rotating and accelerating biological conditions, cavitation inception is best explained only by maximum linear velocity, so in order to study cavitation onset in non-linear kinematic conditions, it is only necessary to match maximum velocity.

A physical model of the extreme mantis shrimp strike: kinematics and cavitation of Ninjabot

In rotating and accelerating biological conditions, cavitation inception is best explained only by maximum linear velocity, and Akaike Information Criterion is used to compare statistical models that correlated cavitation with a variety of kinematic properties.

Inspired by both their mechanical capabilities and evolutionary diversity, research on mantis shrimp strikes has provided interdisciplinary and fundamental insights to the fields of elastic mechanisms, fluid dynamics, evolutionary dynamics, contest dynamics, the physics of fast, small systems, and the rapidly-expanding field of bioinspired materials science.

Linkage mechanics and power amplification of the mantis shrimp's strike

The results of the morphological, kinematic and mechanical analyses suggest a multi-faceted mechanical system that integrates latches, linkages and lever arms and is powered by multiple sites of cuticular energy storage.

Comparative spring mechanics in mantis shrimp

Overall, the study shows a more potent spring mechanism in the faster and more powerful hammering species compared with spearing species while also highlighting the challenges of reconciling within-species and cross-species mechanical analyses when different processes may be acting at these two different levels of analysis.

From telson to attack in mantis shrimp: bridging biomechanics and behavior in crustacean contests.

This multi-level analysis of ritualized fighting in mantis shrimp is comprehensive, but the need to include additional levels of analysis is implored to obtain a truly holistic understanding of this and other crustacean agonistic interactions.

Ritualized fighting and biological armor: the impact mechanics of the mantis shrimp's telson

The mechanical infrastructure of impact resistance in biological armor is revealed and a new window to the biomechanical underpinnings of animal behavior and assessment is opened.

Gearing for speed slows the predatory strike of a mantis shrimp

It is found that a skeletal geometry that creates a large output displacement achieves a slower maximum speed of rotation than a low-displacement system and proposed that transmission efficiency plays a similar role in form–function relationships for skeletal systems in a diversity of animals.

The sweet spot of a biological hammer: the centre of percussion of glyptodont (Mammalia: Xenarthra) tail clubs

A novel method is outlined to determine the centre of percussion (CP) of the glyptodont tail clubs and finds that the largest species had the CP very close to the possible location of horny spikes, consistent with the inference that they were adapted to delivering powerful blows at that point.

Elastic energy storage in the mantis shrimp's fast predatory strike

The remarkable shapes and mineralization patterns that characterize the mantis shrimp's raptorial appendage further reveal a highly integrated mechanical power amplification system based on exoskeletal elastic energy storage.

Electrophysiology and experiments in which the strike has been simulated have shown that the strike is produced by the co-contraction of flexor and extensor muscles in the merus operating a ‘click’ joint.

Biomechanics: Deadly strike mechanism of a mantis shrimp

It is shown that the peacock mantis shrimp (Odontodactylus scyllarus) generates an extremely fast strike that requires major energy storage and release, which is explained in terms of a saddle-shaped exoskeletal spring mechanism.

A more extensive analysis incorporating published data on muscle stresses in other animal groups revealed that stress scales isometrically with the resting sarcomere length among species, as predicted by the sliding filament model of muscle contraction.

A comparison of the strengths of gastropod shells with forces generated by potential crab predators

Carcinus manenas, Liocarcinus puber and Cancer pagurs are thought to be three likely crab predators of the gastropod Calliostoma Zizyphinum, and Carcinus maenas and cancer pagurus were capable of breaking both the shell lips and the whole shells of a wider range of shell sizes than L. puber.

There were no differences in sucker strength among the four octopod species, but seven of the ten decapod species differed from the overall decapod regression curve, including the fast-swimming, open-water species in the decapod sub-order Oegopsida.

Neuromuscular physiology of the strike mechanism of the mantis shrimp, Hemisquilla†

The rapid strike action is explained not in terms of the rapid contraction of these muscles but in their operation of a mechanical device in the form of a “click-joint,” described previously.

How snapping shrimp snap: through cavitating bubbles.

Hydphone measurements in conjunction with time-controlled high-speed imaging of the claw closure demonstrate that the sound is emitted at the cavitation bubble collapse and not on claw closure, and a model for the bubble dynamics based on a Rayleigh-Plesset-type equation quantitatively accounts for the time dependence of the bubble radius and for the emitted sound.


The decrease in hydrostatic pressure generated by octopus suckers adhering to wettable and non-wettable surfaces was measured using a flush-mounted miniature pressure transducer. The cavitation

Fine structure of muscles controlling the strike of the mantis shrimp, Hemisquilla

The ultrastructure of some muscle fibers of the five physiologically different motor units operating the strike of the mantis shrimp were studied by electron microscopy and showed that the rates of both contraction and relaxation are lower the greater the A band or true relaxed sarcomere length.

Snapping shrimp make flashing bubbles

It is shown that a short, intense flash of light is emitted as the bubble collapses, indicating that extreme pressures and temperatures of at least 5,000 K must exist inside the bubble at the point of collapse.
