Conus auratinus is a species of predatory sea snail, a marine gastropod mollusk in the family Conidae, the cone snails. This species is native to the Indo-Pacific region and is known for its distinctive and often highly variable shell patterns.

Description
Conus auratinus possesses a moderately large, solid, and conical shell, typically ranging in length from 50 to 90 millimeters, though some specimens can exceed this size. The shell's spire is usually moderately elevated, and its sides are generally straight or slightly convex.
The coloration and patterning of Conus auratinus are highly diverse, contributing to its appeal among shell collectors. The ground color often varies from white, cream, or yellowish to orange-brown. This base color is typically overlaid with complex patterns of darker markings, which can include reticulated (net-like) designs, axial streaks, spiral bands, or blotches in shades of brown, orange, or black. The aperture (opening) of the shell is usually white or cream. The species name "auratinus" is derived from Latin, meaning "golden," and some forms indeed exhibit rich yellowish or golden tones.
Distribution and Habitat
This species is widely distributed throughout the Indo-Pacific biogeographic region. Its range includes areas such as the Philippines, Indonesia, Papua New Guinea, and other parts of the Western Pacific Ocean.
Conus auratinus is typically found in subtidal marine environments. It inhabits sandy bottoms, rubble areas, and coral reefs, often at depths ranging from a few meters down to 100 meters or more. Like other cone snails, it is a benthic organism, living on or within the seabed.
Biology and Behavior
As with all members of the genus Conus, C. auratinus is a carnivorous predator. It preys on other marine invertebrates, primarily marine worms (vermivorous) or sometimes small fish (piscivorous), depending on the specific form or population. It hunts by using a specialized, venomous harpoon-like radular tooth to inject potent neurotoxins into its prey, paralyzing it before ingestion. The venom of Conus species can be medically significant, and while C. auratinus is not among the most dangerous species to humans, caution is advised when handling live specimens.
Conservation Status
The conservation status of Conus auratinus has not been specifically evaluated by the IUCN Red List. However, habitat degradation and over-collection in some areas could pose localized threats to populations of this and other cone snail species.
