Langridge, K. 2009. Cuttlefish use startle displays, but not against large predators.   Animal  Behavior . 77:847-856. Researchers studied the responses shown by cuttlefish,  Sepia offcinalis,  to different predators  of a varying spectrum of danger and wondered if the identity and amount of threat posed by the  predator would change the way cuttlefish responded. Encounters were simulated between  cuttlefish and their varying predators to observe the way cuttlefish responded to different  predators. It was noted that vivid displays of warning were only directed at smaller, less  threatening predators while threats from larger predators did not elicit the flamboyant response.  This data supported the conclusion that cuttlefish chose which predators to intimidate and by  choosing the small, easily intimidated ones, avoid the risk of attracting the more dangerous  large predators.
