What kind of fish smells like a dog? - briefly
The species of fish that is often associated with a strong odor reminiscent of a wet dog is the Atlantic sturgeon (Acipenser oxyrinchus). This distinctive smell comes from the fish's diet and environment, particularly when it feeds on crustaceans and other bottom-dwelling creatures.
What kind of fish smells like a dog? - in detail
The question "What kind of fish smells like a dog?" often arises due to the peculiar odor that some species can emit. This distinctive smell is not a coincidence but rather a result of specific chemical compounds present in both animals.
Dogs and certain types of fish, such as catfish and sharks, produce trimethylamine oxide (TMAO). TMAO is an organic compound that plays a crucial role in maintaining the osmotic balance in their bodies. In fish, it helps to counteract the high salt concentration in seawater, allowing them to thrive in marine environments. Similarly, dogs have evolved to utilize TMAO for various physiological functions.
When these animals decompose or are processed (such as during cooking), the TMAO breaks down into trimethylamine (TMA). It is this compound that gives off the characteristic fishy smell, reminiscent of a dog's odor. This similarity in scent can be attributed to the shared presence of TMAO in both species.
In summary, the specific type of fish that smells like a dog can vary, but it is particularly noticeable in catfish and sharks due to their high content of trimethylamine oxide (TMAO). Upon decomposition or cooking, this compound breaks down into trimethylamine (TMA), which produces the distinctive odor.
