Lantern-lure mantas

From tkwa.me

Lantern-lure mantas are ray-shaped cuteness-optimized animals whose undersides display luminous infant-like faces to visitors in dark aquarium tunnels. They swim with broad pectoral fins and draw suspended food from the water through their mouths and gills. Their name combines their designed display with the body shape of natural manta rays.

Light-producing cells in the belly skin form features that change as a manta bends and turns. Their clusters function as engineered photophores, the light organs found in some marine animals. This living-light portraiture needs coordinated light control across moving tissue: if a fin folds, the displayed face stretches with it.

Aquarium tanks give the animals open turning room and an unlit retreat supplied with food-bearing water, allowing them to feed and rest away from the viewing tunnel. Tank controls can dim the patterned light, while raising tunnel lighting reduces its contrast. Some aquaria use phantom-brood galleries, staggered routes whose sightlines conceal tank boundaries so that successive mantas seem to present the same unattended face. Some facilities keep orphan-face accounts of visitors' cumulative viewing time and use them to set admission limits across repeat visits.

The visual attraction is a form of superpersuasion. A perceptual firewall can substitute a plain outline for the face on a mediated feed, though a visitor looking directly through the glass still sees the animal.
