For those of you who watched David Attentborough's recent Life in Colour BBC mini-series, you may have spotted one of our photographers, Professor Justin Marshall, discussing how he adapted a polarising camera to work underwater. The camera was used in the series to film Mantis Shrimps and explore their incredible use of polarised light, undetectable to the human eye, as a sort of 'heat map' to spot predators and attract mates.

With the fantastic footage shown on Life in Colour, we thought it was time to re-visit a wonderful collection of very colourful images, taken by Professor Justin Marshall, that we represent here at Image Quest Marine - these images may look like abstract works of art but they are, in fact, incredible close-up shots of fish skin!
