The Mechanism of Color Change in the Neon Tetra Fish: a Light‐Induced Tunable Photonic Crystal Array

Abstract

The fresh water fish neon tetra has the ability to change the structural color of its lateral stripe in response to a change in the light conditions, from blue‐green in the light‐adapted state to indigo in the dark‐adapted state. The colors are produced by constructive interference of light reflected from stacks of intracellular guanine crystals, forming tunable photonic crystal arrays. We have used micro X‐ray diffraction to track in time distinct diffraction spots corresponding to individual crystal arrays within a single cell during the color change. We demonstrate that reversible variations in crystal tilt within individual arrays are responsible for the light‐induced color variations. These results settle a long‐standing debate between the two proposed models, the “Venetian blinds” model and the “accordion” model. The insight gained from this biogenic light‐induced photonic tunable system may provide inspiration for the design of artificial optical tunable systems.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Structural colors in fish usually result from reflection by guanine crystals inside the scales or skin.

    “Indeed, structural colors in fish are not rare, but the colors usually result from the reflection by guanine crystals inside the scales or skin (21, 22), which are obviously missing in the transparent species.”
  • Color pattern can be influenced physiologically, as some types of pigment cells disperse or contract pigment granules in response to endocrine and neuroendocrine factors, including norephinephrine (NE).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
