Bordallo

Descrição

Squalius pyrenaicus, commonly known as Bordallo, is a cyprinid fish endemic to the Iberian Peninsula. It is a medium-sized freshwater fish characterized by its elongated, fusiform body and relatively large head. It is an opportunistic omnivore, feeding on a variety of aquatic invertebrates, algae, and detritus. This species plays a significant ecological role in its native river systems as both a predator and a prey item. Its conservation status is a concern due to habitat degradation and fragmentation.
