Suckfishes
Suckfishes are a group of fish characterized by their ability to attach themselves to other objects or animals using a specialized suction cup-like structure on their bodies. These fishes often have a flattened shape and strong muscular mouths that they use to cling onto surfaces. Suckfishes are typically found in freshwater or marine environments and are known for their unique feeding behavior of attaching themselves to larger animals to feed on their skin or bodily fluids.
