No idea where to post this question, but if sharks have ammonia in the muscle, how are they not negatively affected by it? Are they as sensitive to ammonia as other saltwater fish?
technically speaking is due to they are mamals totally different than a fish they have organs that are different and breath differently as well this is the only way that they can release the toxins with there strenght from muscle tissue
Sharks are not mammals. They do not regulate body temperature like mammals, also, they do not nurse their young, a major factor in being classified mammalian. They are indeed a fish. Just not a bony fish. They are supposed to have existed 420 million years ago, before land vertebrates existed.
