Nannos

Nannos is a genus of small, marine gastropod mollusks belonging to the family Epitoniidae, commonly known as wentletraps. These sea snails are characterized by their delicate, often translucent shells, which are typically spiraled and ribbed. The name "Nannos" itself is derived from Greek and refers to their small size, as these are among the smallest members of the Epitoniidae family.

These mollusks are typically found in tropical and subtropical waters, inhabiting sandy or muddy substrates, often in association with sea anemones. Nannos species are predatory, feeding on the tissues of their host anemones. They possess a specialized radula, a ribbon-like structure of teeth, which they use to scrape or tear away at the anemone's flesh. This predatory relationship is a key ecological feature of the Nannos genus.

Reproduction in Nannos generally involves the laying of egg masses, often attached to the substrate or debris. The larval stage is planktonic, allowing for dispersal. The shells of Nannos, while beautiful, are fragile, and finding intact specimens can be challenging for collectors. Research on Nannos species often focuses on their feeding ecology, reproductive strategies, and the unique adaptations that allow them to thrive in their specific marine environments.
