Conus monilifer, also known as the “monilifer cone shell,” is a species of predatory sea snail, a marine gastropod mollusk in the family Conidae, the cone snails, cone shells or cones. These snails are known for their beautiful and often elaborate shells, which are highly valued by collectors.
Description and Characteristics
Conus monilifer is a relatively large cone shell species, with individuals reaching a maximum size of approximately 150 millimeters (6 inches) in length. Its shell exhibits a characteristic conical shape, with a pointed apex and a wide, flared aperture. The shell surface is typically smooth and glossy, often displaying intricate patterns of brown, orange, and white markings. These markings can vary significantly among individuals, making each shell unique. The shell of Conus monilifer is generally white to gray, with brown to orange markings and rows of prominent, beaded nodules on the spire.
Habitat and Occurrence
Conus monilifer is predominantly found in the Indo-Pacific region, inhabiting tropical and subtropical marine environments. This species prefers shallow water habitats, typically occurring at depths ranging from the intertidal zone to about 50 meters (160 feet). It is commonly found in coral reefs, rocky shores, and sandy bottoms. Conus monilifer is particularly prevalent in the Indo-Pacific’s neritic zone, which extends from the shoreline to the edge of the continental shelf, where it thrives in the diverse and complex ecosystems of this region.
Taxonomy
Conus monilifer belongs to the Class Gastropoda, Order Neogastropoda, and Family Conidae. This classification places it within a diverse and widely distributed group of marine snails, all characterized by their cone-shaped shells and predatory habits.
Feeding
Like other cone snails, Conus monilifer is a carnivorous predator, feeding primarily on other marine invertebrates, including worms, crustaceans, and even other snails. It uses a specialized harpoon-like structure, known as a radula tooth, to inject a venomous neurotoxin into its prey. The venom paralyzes the prey, allowing the cone snail to consume it whole.
