Amplification curves of LAMP assays for the CITES-listed shark species. Rising of fluorescence signals indicates positive amplification. (a) Amplification curves of all 93 species with specific primers for internal control. (b–m) Amplification results of all 93 species with species-specific primers targeting (b) pelagic thresher shark Alopias pelagicus, (c) bigeye thresher shark Alopias superciliosus, (d) common thresher shark Alopias vulpinus, (e) great white shark Carcharodon carcharias, (f) silky shark Carcharhinus falciformis, (g) oceanic whitetip shark Carcharhinus longimanus, (h) basking shark Cetorhinus maximus, (i) porbeagle shark Lamna nasus, (j) whale shark Rhincodon typus, (k) scalloped hammerhead shark Sphyrna lewini, (l) great hammerhead shark Sphyrna mokarran, and (m) smooth hammerhead shark Sphyrna zygaena.
