摘要: Early life stages of cephalopods are somewhat complex due to the history strategy or species specificity generalized ontogenetic patterns and processes. This work aimed determine time length embryonic development at different temperatures, if egg size is a determinant hatchling in Sepiola atlantica d′Orbigny, 1839–1842. Successful hatching occurred 98.5–100% eggs for each female. As seen other coleoid cephalopods, temperature determines amount S. atlantica, obtained data were very similar cephalopods. Developmental times temperatures 13 ± 0.4°C, 18 0.3°C 16.4 1.1°C 61.8 3.8, 22.6 1.7 40.1 4.8 days. The duration mantle was not strictly related. volume positively related length. Our results provide new records on embryogenesis information reproductive this species. Some post-hatching behaviour shown discussed.
