Conus julii is a species of marine gastropod mollusk in the family Conidae, commonly known as cone snails. It was first described by Émile Liénard in 1870. Like all members of the genus Conus, it is predatory and possesses a venomous harpoon‑like radular tooth capable of delivering a sting to humans; live specimens should therefore be handled with caution or not at all.

Description
The shell of C. julii ranges from 32 mm to 62 mm in length. It is primarily white, with the upper portion of the body whorl, the spire, and the interior exhibiting a pink tinge. Longitudinal chestnut‑colored striations run along the body whorl, forming two irregular bands.
Distribution and Habitat
Conus julii occurs in the Indian Ocean, specifically off the coast of Mauritius and throughout the Mascarene Basin. It inhabits marine environments where it preys on other small invertebrates.
Ecology
As a predatory cone snail, C. julii employs a specialized venom apparatus to immobilize prey. The venom contains conotoxins, which can be medically significant in rare cases of human envenomation.
Conservation Status
The International Union for Conservation of Nature (IUCN) lists Conus julii as Vulnerable (IUCN Red List version 3.1, assessment 2025). Threats include habitat degradation and collection for the shell trade.
