Salt secretion via specialized gill cells occurs in marine vertebrates that constantly absorb salt through thin membranes of their oral, respiratory, and body surfaces (see respiration ). Gaseous wastes are eliminated by diffusion, and solid wastes in dissolved or undissolved form pass out through an opening in the body wall that serves the dual purposes of food intake and waste elimination. The amount of dissolved oxygen in streams is dependent on the water temperature, the quantity of sediment in the stream, the amount of oxygen taken out of the system by respiring and decaying organisms, and the amount of oxygen put back into the.

Oxygen dissolved in water is used by aquatic animals for respiration and survive. Once the reaction is fixed, introduction of additional oxygen does not affect the results of the titration. They can breathe dissolved oxygen in water (through the gills or skin) or they can breathe it from the air (through the lungs). Aquatic animals excrete cell waste in gaseous form (ammonia) which directly dissolves in water.
