On what surface is the Ambulcaral groove visible on a star fish?
Echinoderms can have ambulacral parts that include ossicles, plates, spines, and suckers. For example, sea stars or "star fish" have an ambulacral groove on their oral side (underside). This ambulacral groove extends from the mouth to the end of each ray or arm. Each groove of each arm in turn has four rows of hollow tube feet that can be extended or withdrawn. Opposite the ambulacral groove is an ambulacral ridge on the aboral side of each ray.
Is a trench that runs along the ventral surface of the starfish's arms and holds the tube feet?

If your asking where it is, its on the Ventral(bottom) side. It is the indent in the starfishes' skin that goes through all of the starfishes' rays (arms). It is called the ambulacral groove.
What is the main function of the ambulacral system in ehinoderm?
The main function of the ambulacral system in echinoderms is to facilitate movement, respiration, and feeding. It consists of a series of fluid-filled tube feet that help echinoderms to crawl, capture food, and exchange gases with the surrounding environment.

What is the function of Piston ring groove?
The piston ring groove serves as a seating area for piston rings within an engine's piston. Its primary function is to maintain a seal between the piston and the cylinder wall, preventing the escape of combustion gases and controlling oil consumption. Additionally, the groove allows for axial movement of the rings, accommodating thermal expansion and ensuring proper ring function during engine operation. Proper design and maintenance of the groove are essential for optimal engine performance and longevity.
What is caudothalmic groove?
The caudothalamic groove is an anatomical feature in the brain, specifically found on the medial surface of the thalamus. It is the indentation or groove that separates the thalamus from the caudate nucleus, which is part of the basal ganglia. This groove plays a role in the organization and connectivity of neural pathways in the brain, contributing to its overall function. Understanding its anatomy is important in neuroanatomy and neurosurgery.
