A recent study has found that although, ordinarily, cuttlefish hatchlings prefer shrimp-like prey, when visually exposed to crabs in the first hours of day one, they later prefer crabs to shrimps. As the development of this preference occurs during a short sensitive phase, does not depend on food ingestion and is long lasting, it fulfils all the criteria for imprinting, a phenomenon more usuall...

Salmonellosis caused by contaminated cuttlefish chips spread throughout Japan from December 1998 to May 1999. We first identified Salmonella Oranienburg (1,2) and S. Chester (3,4) as causative agents. During the outbreak, we obtained 62 S. Oranienburg and 12 S. Chester isolates from diarrhealstools collected in Hyogo Prefecture in the central part of Japan. However, the source of isolation was ...

In the winter of 2015, a skin ulcer disease outbreak occurred in a pharaoh cuttlefish Sepia pharaonis population cultured on a land-based fish farm in China. Affected cuttlefish (about 60% of the population) were characterized as having developed ulcers on the dorsal skin, fin fringe, or distal mantle tip. Masses of a ciliated protozoan were isolated from skin ulcers. The ciliate was identified...
