meglyman: nubbsgalore: despite its colourful appearance, the hawaiian bobtail squid (euprymna scolopes) has the ability to render itself invisible to predators from bellow, thanks to a luminescent bacteria, vibrio fischeri, which inhabits a special light organ in the squid’s mantle. the bacteria, which are fed a sugar and amino acid solution by the squid, are able to prevent their nocturnal hosts from being silhouetted when passing though the light of the moon or stars by emitting an equal amount of light on its underside to that which hits the top of the squid. photos by mattias ormestad, jackson wong, jose martín piñatel, david slater, todd bretl Shiiiiiiny -- source link
