Deimatic defensive behavior (for definition see Hanlon and Messenger, 1996) by S. latimanus to an artificial fish threat. The young cuttle assumes a vertical head-high body posture presenting the dorsal mantle to the threat with multiple dark spots on a light background. This was a strongly stereotyped behavior. Note the cuttlefish just below the inverted animal that still has the patterning on the dorsal mantle even though it has returned to a horizontal posture.
Maturity: Juvenile; Lab or Wild: Lab; Origin: S. pacific, palau
