How a European eel sees your lure
Which lure colour a European eel can actually see, at your depth and in your water. 2 cone types, peak 525 nm. Ranked contrast for 54 colours.
Anguilla anguilla
Measured for this species
Cone peaks are direct measurements for this species. The rest of the model — water optics, contrast, detection distance — is still an estimate, and none of it predicts whether a fish will strike. The eel rebuilds its visual pigments when it silvers for the ocean migration, shifting sharply to the blue. This profile is the silvered state; a yellow eel in a river is measurably more green-sensitive.
Spectral sensitivity
| Cone peaks | λmax | Chromophore |
|---|---|---|
| Short | 435 nm | A1 |
| Medium | 525 nm | A2 |
| Rod | 487 nm | A1 |
Rods do the work at dawn, dusk and night — which is when most people fish.

Questions people actually ask
Can a European eel see colour?
Yes, but only just. It has 2 cone types, peaking at 435 nm, 525 nm, so it has a single dimension of hue where a human has 2.
Where does this data come from?
Direct microspectrophotometry, ERG or behavioural spectral sensitivity for this species.
