    Have you ever wondered about the secret life of the tasty lobster(龙虾)？In the sea, it is yellow, orange, grey, green, brown or even blue. Cooking turns it red.

    Lobsters are nocturnal creatures(夜行物)，so it is best to hunt(捕捉) them at night when they are active. You can catch lobster by hand, but you should wear thick gloves because lobster's claws are strong. A very large lobster could break your finger.

    Interestingly, in the past, lobsters were only served to prisoners as they were considered as a poor man's food. Nowadays, lobsters are an expensive and popular dish.
