Shooting Mechanisms in Nature: A Systematic Review
Fig 25
Linkage and latch catapult mechanism in the phylum Stomatopoda (species Odontodactylus scyllarus).
(A) The appendage of the mantis shrimp consisting of a saddle-shaped elastic structure located between the merus and the propodus. (B) Compression of the saddle and latching of the propodus by the simultaneous contraction of the extensor and flexor muscles. (C–D) Release of the latch by relaxation of the flexor muscle, allowing outward movement of the propodus. Drawings based on schematic drawings in [133]. Scale bar indicates the length of the propodus, which is in between 3 and 40 mm.
