Ambulacral Grooves

Description: Ambulacral grooves are a series of furrows or channels found on the undersides of the arms of certain marine animals, such as starfish and sea urchins. They are vital structures used for locomotion, respiration, and feeding.

Sample sentences:

1. The starfish moves by using its ambulacral grooves to generate a hydraulic pressure that propels it across the ocean floor.
2. In sea urchins, the ambulacral grooves serve as a pathway for the tube feet, which aid in movement and capture of food.
