FIGURE 3 An X-ray image of a section showing band pair progression of an oxytetracycline (OTC)-marked Alopias vulpinus recaptured in the northeastern Pacific Ocean. Translucent cartilage (dark bands on image) alternated with more-calcified cartilage (appearing light on image). Opaque, hypermineralized bands are marked with a solid dot; 4 band pairs post birth band and 3.5 band pairs post-OTC. The OTC mark and birth band are labeled. Tagged A. vulpinus A039014 was at liberty 3.81 years, measured 80 cm fork length (LF) at the time of tagging, and 140 cm LF at recapture.
