The Toronto Zoo added a lake sturgeon to its animal collection on Sunday [2].
The addition aims to educate visitors about the long evolutionary history of the species and highlight a charismatic freshwater fish native to Canada [1].
Zoo officials described the fish as a living fossil. A spokesperson for the Toronto Zoo said the lake sturgeon is considered the most charismatic of Canadian freshwater fishes and has been swimming in the country's waters for more than 150 million years [1].
The species is often viewed as a descendant of the dinosaurs due to its ancient lineage. The zoo's representative said the fish is remarkable and misunderstood [2].
By bringing the lake sturgeon into the facility, the zoo intends to provide a closer look at a species that has remained relatively unchanged over vast geological timescales. The exhibit is designed to foster an understanding of freshwater biodiversity, and the persistence of ancient lineages in modern ecosystems [1].
“Lake sturgeon have been swimming our country's waters for more than 150 million years.”
The inclusion of the lake sturgeon at the Toronto Zoo serves as a public education tool for evolutionary biology. By showcasing a 'living fossil,' the institution emphasizes the concept of evolutionary stasis—where a species undergoes little morphological change over millions of years—while drawing attention to the conservation of Canada's freshwater biodiversity.
