The fishes are about 1.5 meters long and look like carps(鲤鱼). There will be a detector intheir bodies. They canfind the sources of pollutionin the water, and then the robot fisheswilleat part of it.

After their batteries die, they will return by themselves.
There are five robot fishes altogether now.Each costs about 29,000 dollars. They are partof a three-year project between engineering company BMT Group and Essex University insoutheastern England.
“We designed the fishes creatively. We hopethe robot fishes can find the changes in the seawater and report back the information,” said Professor Huof Essex University. His team isdeveloping the fishes.

B.$29,000.
C.$145,000.
D.$1,450, 000.
Which of the following is TRUE? The robot fishes ____.A.can eat anything in the water
B.need to be controlled by people
C.are 1.5 meters long andthey look like sharks
D.cango back to the beach when the batteries run down
