Which organism is NOT a filter feeder?

Explanation

Filter feeders are a sub-group of suspension feeding animals that feed by straining suspended matter and food particles from water, typically by passing the water over a specialized filtering structure. 

Mosquito larvae are usually filter-feeders. They have fan-like mouth brushes that sweep water at their mouths from in front of them.

In this method they filter out small particles of decaying material and microorganisms, which they then eat.

While adult mosquitoes are one of many species of fluid-feeding insect.
