Statolith microstructure and maximum age of the sepiolid Rossia pacifica (Cephalopoda, Sepioidea) in the northern part of the North Pacific
Statolith microstructure was studied in eight specimens of the boreal sepiolid Rossia pacifica (mantle length ranging from 45to 90mm) caught on the continental slope of Northwest Bering Sea. Growth increments were presented in all ground statoliths and were narrow and uniform width (average 3.2 - 3....

| Summary: | Statolith microstructure was studied in eight specimens of the boreal sepiolid Rossia pacifica (mantle length ranging from 45to 90mm) caught on the continental slope of Northwest Bering Sea. Growth increments were presented in all ground statoliths and were narrow and uniform width (average 3.2 - 3.3µm). They were grouped into inner opaque and outer translucent growth zones. The total number of growth increments within the statoliths of mature males (75-78) was lower than of mature females (95-117 increments). Assuming growth increments to be laid down daily, the life span from hatching to death of R. pacifica in the Bering Sea may be 4-5 months. |
