Fish anatomy question

What's the that curving line on the top area of the fish body?

Well, your description is a little vague, but if you're talking about the horizontal line of "dots" about a fifth to a quarter of the way down the fishes body (starting immediately behind the eye), that's referred to as the lateral line. IIRC, the pores are actually sensors that allow the fish to detect subtle changes in pressure, chemical, and even electrical current levels in the water.

Yup, that would be the lateral line. Kevin's description of it is pretty darn good too

so its a sensory "organ"? Is it like skin then?

Isn't that what the fish use to detect each other in a school and to stay in their proper spot, turn at the right times, etc.
