Movie S1. Neurally activated iridescence in squid iridophores

This video shows that "Intact fin" preparation yields a green iridophore phenotype when a nearby nerve branch is stimulated through a proximal suction pipett...

Nerves Innervate Color-Changing Iridophores in Squid Skin

Yellow, red, and brown chromatophores (organs composed of a large pigment cell) surround a single iridophore, which consists of hundreds of iridescence cells...

Movie S4. Iridocyte flickering alters iridophore appearance

This video shows patches of iridocytes within some iridophores were often observed to "flicker". In this video, the group of iridocytes in the top part of th...

Movie S3. Structural colouration and peak reflectance have separate mechanisms

This video shows neurally stimulating tissue where the fin muscle and ventral skin (both below the iridophore layer) had been removed, results in a red pheno...

Movie S2. Tissue connectivity is essential for structural colouration

This video shows a preparation, with the layers below and above the iridophore layer removed, such that only the nerves, iridophores and connective tissue re...

Cuttlefish : Electric Skin

Was lucky to meet a live cuttlefish while at work... The cuttlefish has amazing skin. Layers of skin cells (chromatophores, iridophores) enable the animal to...

two minutes in an octopus's garden

Octopuses are masters of camouflage; able to change their skin colour within seconds so that they blend into the environment around them; a process that work...

See-thru Guppies from Guppy Designer

These are the result of a combination of three recessive genes that genetically remove all the color cells, except some iridophores in the tail fin. Very use...

Supplementary movie

This video shows a water droplet repeatedly brought into contact with an intact brochosome-coated leafhopper wing. This research was published in the journal...

Supplemental Video: Condition P_minus

This video shows a representative trial of condition P_minus: robot beats its tail slower as fish approaches it. This research was published in the Journal o...
