[never expected] the professor of the first South army had done such a thing to crayfish

rayfish season,
the streets filled with assorted lobster shop! Braised in yellow,
thirteen fragrant.
Delicious to stop! No Under the! Come! The folk have been circulating such a saying,
said crayfish like to stay in the foul ditch,
eating rotten food,
eating will be bad for the human body,
which in the end is true or false? Finally,
the question has an answer! Recently,
Huang Cheng,
an associate professor at the school of life sciences at Nanjing University,
took his students to do lobster experiments to restore the real features of crayfish! They found that crayfish do not like the sewage environment,
nor eat rotten food.
[experiment secret] crayfish like sewage? NO: 80% crayfish choose clean water environment,
Huang Cheng told reporters,
he and students have done a maze experiment.
