Conus ferrugineus is a species of predatory sea snail, a marine gastropod mollusk in the family Conidae, the cone snails, cone shells or cones. Like all species within the genus Conus, these snails are venomous and capable of “stinging” their prey with harpoon-like radular teeth.
Description & Characteristics
Conus ferrugineus typically has a moderately sized, heavy shell with a pointed spire. The shell is usually a rich reddish-brown color with white spots or blotches, giving it its name “ferrugineus,” which means “rusty” in Latin. The shell’s surface can be smooth or have fine longitudinal ribs. The maximum size of this cone snail can reach 80 millimeters in length.
Habitat and Occurrence
Conus ferrugineus is found in the Indo-Pacific region, specifically in the tropical waters of the Indian Ocean and the western Pacific Ocean. It prefers shallow, rocky or sandy habitats, often hiding under coral rubble or in crevices. This species is commonly found in the intertidal zone, where it can be exposed to air during low tide, as well as in the subtidal zone, which is permanently submerged. This snail typically occurs in depths ranging from the surface to 50 meters.
Taxonomy
The species Conus ferrugineus belongs to the class Gastropoda, which encompasses a vast array of snails and slugs. It further falls under the order Neogastropoda, a group of predatory marine snails characterized by their well-developed siphon and their typically carnivorous diet. Within this order, it belongs to the family Conidae, a group known for their venomous harpoon-like teeth used to subdue prey.
Feeding
Like other cone snails, Conus ferrugineus is a carnivore, feeding primarily on worms, small fish, and other mollusks. It uses its venomous harpoon-like teeth, located on its radula, to paralyze its prey. The venom is a complex cocktail of neurotoxins that quickly incapacitates the target. Once the prey is subdued, the cone snail uses its radula to draw the prey into its mouth and consume it. The effectiveness of Conus ferrugineus‘s venom makes it an efficient predator in its marine environment.
