Gibbula magus is a species of marine gastropod mollusk in the family Trochidae. This sea snail is commonly found along the rocky coastlines of the Mediterranean Sea, including the Comunidad Valenciana.

• Shell Appearance: The shell of Gibbula magus is relatively small and distinctly conical. It features a series of spiral ridges and is typically adorned with various color patterns, ranging from brown to green with potential reddish or pinkish hues.
• Size: The size of the shell generally measures between 15 mm to 20 mm in diameter.
• Habitat: Gibbula magus tend to reside in shallow, rocky coastal areas where they can graze on algae. These snails are often found between the tides, clinging to substrates that support their feeding habits.
• Behavior: This species is primarily herbivorous, scraping off algae from the rocks using their radula, which is a specialized feeding organ unique to mollusks.
• Distribution: Besides the Mediterranean, Gibbula magus may also be found along the Atlantic coasts of Europe, making them a common sight for marine enthusiasts and those exploring the local biodiversity of the Comunidad Valenciana.
• Conservation: While not currently considered endangered, like many marine species, Gibbula magus relies on healthy, uncontaminated waters for survival.

The presence of Gibbula magus in the rocky habitats of the Comunidad Valenciana is a testament to the rich marine biodiversity of the region. Observing these small yet fascinating creatures offers insights into the health and balance of the local marine ecosystem.
