Parks Canada scientists announced Wednesday what they are calling "the most significant freshwater discovery in decades" — a previously unknown species of bioluminescent fish found at 180 metres depth in Lake Louise, Alberta, identified by an autonomous underwater drone.
The Aurora ROV, a research drone equipped with advanced AI vision systems and spectrographic sensors, was conducting a routine biodiversity survey when it observed an unusual light pattern near the lake's thermal vent system. The drone's onboard AI flagged the sighting as a potential novel species within seconds.
Researchers have tentatively named the species Photinus canadensis louise — "Canadian light of Louise." It is theorized to have evolved in complete isolation in the lake's deepest thermal pocket, developing bioluminescence as a hunting mechanism in total darkness.
The discovery has significant implications for research into extreme-environment biology, anti-cancer compounds (bioluminescent proteins have medical applications), and the broader story of Canadian biodiversity. Parks Canada has announced a new deep-lake research program beginning in 2027.
