Mollusca Monoplex parthenopeus, commonly known as the Parthenopean Triton, is a species of sea snail belonging to the family Cymatiidae. This marine gastropod mollusk is found along the Mediterranean coast, including the waters of the Comunidad Valenciana.

The Monoplex parthenopeus is notable for its distinct shell, which is typically robust and features a series of varices or ridges. The shell's color can vary but often presents a brownish or creamy hue with intricate patterns that provide camouflage against the ocean floor.

• Habitat: This species is usually found in rocky substrates or areas with abundant sea vegetation, where it can find shelter and food.
• Diet: As a carnivorous snail, it predominantly feeds on other marine invertebrates, capturing prey with its long, extendable proboscis.
• Distribution: Primarily distributed throughout the Mediterranean Sea, including regions like the Comunidad Valenciana, which offers suitable habitats for its survival.

The Monoplex parthenopeus plays a pivotal role in the marine ecosystem, contributing to the balance of prey and predator populations. Its presence in the waters of the Comunidad Valenciana adds to the rich biodiversity of the region, making it a subject of interest for marine biologists and enthusiasts alike.
