The eye of the Glasseye (Heteropriacanthus cruentatus)


Subject: The eye of the Glasseye (Heteropriacanthus cruentatus), a member of the Bigeyes family (Priacanthidae), is extremely well adapted for life in obscure milieus. They have, like all other Bigeyes family members, big spherical lenses and photoreceptors specialized to see in dark and low-light environments. This nocturnal feeder of small octopuses, tiny squids, crabs and shrimps is also able to rapidly intensify and fade its reddish colour and silver patterns.

Technique: To make this reddish fish stand out we’ve desaturated the pinkish/purplish algae shrubbery in the foreground slightly.
