Question

Quizplus · Accepted Answer

Suspension feeding is a feeding mechanism in which organisms use specialized structures to capture small food particles from the surrounding water. In the case of brittle stars that use tentacle-like appendages to capture large food particles, they are not using a radula (a tongue-like organ with small teeth used for scraping food), clawlike appendages, or nectar feeding (feeding on sugary plant fluids).
