Description:HIDE AND SEEK IN THE OPEN SEA:\nPELAGIC CAMOUFLAGE AND VISUAL C
 OUNTERMEASURES\n\nCamouflage is exceptionally challenging in pelagic envir
 onments\, due to their featureless nature. Thus\, it is perhaps no surpris
 e that pelagic species have evolved highly sophisticated cryptic strategie
 s\, three of which – transparency\, mirrors\, and counterillumination â€
 “ are rare or absent in all other habitats. Pelagic visual systems are equ
 ally complex\, and several visual capabilities\, including UV and polariza
 tion sensitivity and intraocular filters\, are thought to facilitate detec
 tion of camouflaged animals. This talk reviews the optical nature of the p
 elagic realm and both the camouflage and camouflage-breaking strategies of
  its inhabitants\, focusing primarily on underlying principles and what re
 mains to be discovered. A theme throughout is that far more is known about
  the optical and visual structures involved than about their function\, an
 d that this imbalance is primarily due to the rarity of observations of un
 disturbed behavior. 4:00 pm
