Their distinctive feature is an oval cross-section, which contrasts with the mostly circular shapes of natural and man-made stingers. However, the reason for their eccentricity remains poorly understood. We explore the hypothesis that the morphology of prickles is physically limited by trade-offs between bending, buckling and cutting. In our experiments, polydimethylsiloxane stingers with varying cross-sectional shapes were used to lacerate a gelatin skin analogue. Circular stingers bend along the direction of travel and create superficial scratches. By contrast, prickles with a moderate aspect ratio have enough mechanical stability to cut (or provide grip). However, when they become too narrow, the blades weaken and buckle. The least unfavourable aspect ratio falls between 2 and 4, not inconsistent with the available biological data (2.7\u00b10.7). This novel mechanical trade-off suggests that cutting mechanics are a potential driver of the rose prickle morphology.<\/jats:p>","DOI":"10.1098\/rsif.2025.1300","type":"journal-article","created":{"date-parts":[[2026,8,12]],"date-time":"2026-08-12T00:09:17Z","timestamp":1786493357000},"source":"Crossref","is-referenced-by-count":1,"title":["Mechanical limits shape the eccentric form of rose prickles"],"prefix":"10.1098","volume":"23","author":[{"given":"Sabrina","family":"Gennis","sequence":"first","affiliation":[{"name":"Department of Physics, Technical University of Denmark 1 , Kgs.
