How is a white sturgeon like a araimpa?

The white sturgeon and the araimpa (a type of fish found in the Amazon) share similarities in their ecological roles as large, ancient fish within their respective habitats. Both species are important for their ecosystems, contributing to the health of aquatic environments. Additionally, they exhibit unique adaptations for survival, such as specialized feeding mechanisms, and both are considered vulnerable due to habitat loss and overfishing. However, they belong to different families and inhabit distinct geographical regions.
