Some may know suckermouth armored catfish as "window cleaners" from aquariums because they possess a suckermouth, which allows them to attach to various surfaces. The attachment is not only enabled by a vacuum created by the fish but also by specific structures of their mouths, which enable an interlocking and adhering to surfaces. A team of researchers closely examined these unique suckermouths and summarized their findings in a recent study published in Frontiers in Zoology.
