True Facts: Fish That Suck #FISH

Fish that use suction to attach themselves to surfaces are known as "suckerfish" or "sucking loaches." These fish possess specialized mouth structures that allow them to create a vacuum-like seal on surfaces, which helps them stay attached to various substrates such as rocks, glass, or other fish. This adaptation assists them in feeding and navigating in their aquatic environments. Some well-known examples of sucking fish include plecos, otocinclus catfish, and hillstream loaches.
