Cancer setosus: morphometric measurements of zoeal stages for a Zoea II larvae incubated at 16, 20, and 24°C and b Zoea III larvae incubated at 16 and 20°C in Antofagasta (23°45′ S), Chile. Measures given are: total length (TL), the distance between the tip of the rostral and the tip of the dorsal spine (r–d), lengths of the rostral, dorsal, and lateral spine, the carapace length (CL) and the antenna length. For details on measurements see “Materials and methods” section. Significant differences are marked with different letters (ZII: p < 0.01, ZIII: p < 0.05)
