Detailed Description and Morphological Assessment of Sepia typica (Steenstrup, 1875) (Cephalopoda: Sepiidae)

A detailed systematic account of Sepia (Hemisepius) typica, an endemic southern African species cuttlefish, is presented. An analysis morphological data (morphometric and meristic characters) suggests that S. typica a single well-established without morphs or subspecies. It is, however, highly variable, perhaps more so than other small sepiids from the region, there are slight, but significant indications population structure. Therefore, molecular biological studies based upon large sample could help investigate broad genetic patterns in what morphologically appears to be variable species.
