The cuttlebone development of common cuttlefish [Sepia officinalis (Linneaus, 1758)]

14481

The cuttlebone development of Sepia officinalis, which is an important criterion for its embryonic development, was redefined as detail during the 30 stages of embryonic development. At stage 24+(XIV), the cuttlebone begins to be formed and the calcareous site can be seen. At stage 26(XV-XVI), first camber can be seen on the cuttlebone, but there is no air in it. At stage 27(XVI-XVII), the first camber is completed, and at the inside instead of its gelatinous-fluid contents, some gas appears in the form of irregular bubble squeezed. At stage 30(XX), newly hatchling has got 7-8 air cambers on the cuttlebone.
