Why does shark meat smell like urine? 1Why are dolphins not afraid of sharks?Dolphins are not afraid of sharks because sharks usually travel alone, while dolphins live in groups. The dolphin's most powerful weapon is its beak, which can pierce sharks with special bones at high speeds and cause their internal organs to rupture and die. Dolphins can also emit sound waves that make sharks feel uncomfortable, which greatly stimulates the shark's brain. 2Can sharks be eaten?Sharks can be eaten. Most of the sharks sold in the domestic market are farmed sharks for consumption. Before cooking sharks, it is recommended to scald the sharks in boiling water, because there is a lot of sand on the shark's skin. Scalding can effectively remove the sand in the skin, making the shark meat taste better. 3Why does shark meat smell like urine?Because the urinary system of sharks is quite special, the excretory system and reproductive system of sharks are all concentrated together. When this system cannot meet the excretion needs of sharks, some of the excrement will be excreted through the shark's skin. If this continues for a long time, the shark's meat will have a urine smell. |
