Click beetles store work to amplify power a thousandfold by deforming their external cuticle.

“And that’s where energy storage comes in. Down to the size of a trout or a squid tentacle, unaided muscle can do a decent job with nothing more than ordinary leverage. Below that, muscle needs help; in practice, energy is put in slowly and stored elastically. Some kind of trigger then releases it at a higher rate. Work and energy may be conserved, but power gets amplified…A click beetle stores up work by deforming the external cuticle; its power amplification is fully a thousandfold (Evans 1973). Each of these creatures has some kind of a mechanical catch to prevent premature extension while the work is being put in; the specific arrangements, though, are different for each case.” (Vogel 2003:476)
