Transcribed Image Text:The image shows a starfish (sea star) in its natural habitat, on the ocean floor surrounded by various marine elements like algae and rocks. The starfish has a spiny surface with multiple arms, characteristic of its species.
A white arrow labeled "A" points to a specific feature on the starfish, which appears to be the madreporite. The madreporite is a critical component of the starfish's water vascular system, functioning as an entry point for seawater. This system is essential for locomotion, feeding, and respiration in echinoderms.
This visual aids in understanding the anatomy and function of the madreporite in echinoderms like starfish.
