title: TABLE 2 in The lionfishes: Comparative development of Pterois volitans, Dendrochirus barberi, and D. hemprichi (Scorpaeniformes: Scorpaenidae: Pteroinae) and discrimination of their early life stages from non-pteroine scorpaenid genera in the Western North Atlantic

description: TABLE 2. Pterois volitans, Dendrochirus barberi, and D. hemprichi morphometrics by life stage. Mean (range). Abbreviations: standard length (SL); head length (HL); orbit diameter (OD); body depth at cleithrum (BDc); caudal-peduncle depth at terminal margin of dorsal-fin base (CPD); caudal-peduncle length (CPL); posterior shelf of preopercle (PPO); character not developed (ND). Asterisk indicates morphometric not available due to specimen damage. Dorsal-fin base length to SL ratio excluded for the aberrant 12.9 mm P. volitans larva lacking first three dorsal spines and associated structures.
