Stupid as a Fish?

In challenging the misconception that fish lack complexity compared to mammals, Horst Bleckmann, professor emeritus of sensory and neurobiology at the University of Bonn, sheds light on the advanced cognitive abilities of these aquatic creatures. 

With approximately 30,000 species, fish are the largest group of vertebrates and inhabit all aquatic environments. They exhibit a diverse range of specialized sensory systems and behaviors. Recent studies unveil their highly sophisticated sensory organs and well-developed central nervous systems, akin to those found in mammals. 

Furthermore, Bleckmann addresses pressing environmental threats such as water pollution, habitat degradation and overfishing, highlighting the urgent need for conservation efforts to protect fish populations worldwide.
