Coleoid cephalopods (octopuses, squids and cuttlefishes) are the only branch of the animal
kingdom outside of vertebrates to have evolved both a large brain and camera-type eyes …

Many cephalopods escape detection using camouflage. This behaviour relies on a visual
assessment of the surroundings, on an interpretation of visual-texture statistics,–and on …

With their large brains, elaborate sense organs and complex behaviour, cephalopods are
among the world's most highly evolved invertebrates. This second edition summarises the …

We review recent research on the visual mechanisms of rapid adaptive camouflage in
cuttlefish. These neurophysiologically complex marine invertebrates can camouflage …

Camouflage is a widespread phenomenon throughout nature and an important antipredator
tactic in natural selection. Many visual predators have keen color perception, and thus …

Color change serves many antipredator functions and may allow animals to better match
environments or disrupt outlines to prevent detection. Rapid color change could potentially …

Sleep is a state of immobility characterized by three key criteria: an increased threshold of
arousal, rapid reversal to an alert state and evidence of homeostatic 'rebound sleep'in which …

ABSTRACT A major component of cephalopod adaptive camouflage behavior has rarely
been studied: their ability to change the three‐dimensionality of their skin by morphing their …

Coleoid cephalopods adaptively change their body patterns (color, contrast, locomotion,
posture, and texture) for camouflage and signaling. Benthic octopuses and cuttlefish …

To achieve effective visual camouflage, prey organisms must combine cryptic coloration with
the appropriate posture and behaviour to render them difficult to be detected or recognized …
