Stickiest fish

The Northern Clingfish (Gobiesox maeandricus) is a small fish commonly found along the Pacific coast of the United States and Canada. It would be fairly unremarkable among the over 170 species of clingfish worldwide - except it is the world’s stickiest fish, with an adhesive force measured between 80 to 230 times its body weight, according to a study published in 2013. The fish uses a modified suction cup located on its belly to cling to rocks in strong currents and tides. The clingfish suction cup uses on tiny hairs called microvilli which prevent the cup from slipping even on rough or irregular surfaces. This is the same method the gecko uses to stick to walls and ceilings.
