Question

Quizplus · Accepted Answer

The term "sessile" refers to animals that live attached to a substrate or surface and do not move around. Therefore, this is the best choice as it specifically refers to animals that are attached to the bottom. Benthic motile animals can move around on the bottom, while infaunal animals live within the sediment and interstitial animals live in the spaces between sediment particles, but neither of these terms specifically refer to animals that are attached to the bottom.
