Do fish drink breathe out the same hole?

No, fish breathe and drink through different openings. Fish breathe through their gills, which are located on both sides of their heads. Gills are made up of thin filaments that are covered in tiny blood vessels. As water passes over the gills, oxygen from the water is absorbed into the blood vessels. Carbon dioxide, a waste product of cellular respiration, is released from the blood vessels into the water.

Fish drink by swallowing water through their mouths. The water then passes through the fish's digestive system, where nutrients are absorbed. The remaining water is expelled through the fish's anus.
