do fish drink water

Fish do not drink water in the same way that humans and other animals do. They obtain the water they need through their food and by absorbing it through their skin and gills.

Fish live in water and their bodies are adapted to the aquatic environment. Fish use their gills to extract oxygen from the water and to excrete waste products. The water enters the fish's body through the mouth and then passes over the gills, where oxygen is extracted and carbon dioxide is released.

Fish also absorb water through their skin, which helps to maintain their body's water balance. Fish also excrete their waste product through the gills. Fish are able to live in different types of water environments like freshwater and saltwater, each fish species have their own unique adaptations.

Fish in freshwater environments have a higher concentration of ions in their blood than in their environment, while fish in saltwater environments have a lower concentration of ions in their blood than in their environment.
