<human>: Is it safe to eat fish that is still alive when I buy it?
<bot>: It depends on the type of fish. Some types of fish can be eaten while they are still alive, such as sardines and anchovies. Other types of fish should not be eaten if they are still alive, including tuna, swordfish, shark, and marlin. If you’re unsure about whether a certain type of fish can or cannot be eaten while still alive, it is best to ask your local fishmonger before purchasing the fish.
