Tuna, like other fish, excrete waste primarily through their gills and anus. Ammonia, a byproduct of protein metabolism, is expelled through the gills into the surrounding water, while solid waste is eliminated through the anus. This process helps maintain their internal balance and removes toxic substances from their bodies. Additionally, the high water flow through their gills aids in the efficient removal of waste products.
