Vertical Visual Features Have a Strong Influence on Cuttlefish Camouflage

Congratulations to Kimberly Ulmer, research assistant in the Program in Sensory Physiology & Behavior and lead author of the recent paper “Vertical Visual Features Have a Strong Influence on Cuttlefish Camouflage” that was published in the MBL’s Biological Bulletin.  She, along with other members of the Hanlon lab, discovered that visual stimuli in the vertical dimension (2D or 3D) have a stronger influence on changeable camouflage in Sepia officinalis than do 2D stimuli presented horizontally. Moreover, this effect is noteworthy because in many of the experiments, the stimuli presented vertically constituted only a small proportion of the total visual surrounds, indicating that cuttlefish are selectively responding to vertical cues.
