Definition
Conus immelmani is a species of marine gastropod mollusk in the family Conidae, commonly known as cone snails. Like all members of the genus Conus, it is predatory and possesses a venomous harpoon‑like radular tooth used to capture prey.
Overview
-
Taxonomy:
- Kingdom: Animalia
- Phylum: Mollusca
- Class: Gastropoda
- Order: Neogastropoda
- Family: Conidae
- Genus: Conus
- Species: C. immelmani
-
Discovery and Authority: The species was formally described by Röckel & da Motta in 1983 (the exact publication year may vary in sources).
-
Distribution: Reported occurrences are limited to the western Indian Ocean, particularly off the coast of eastern Africa. Precise locality records are scarce, and the full geographic range remains incompletely documented.
-
Habitat: C. immelmani inhabits tropical marine environments, typically residing on sandy or rubble substrates in shallow reef-associated waters.
Etymology/Origin
The specific epithet immelmani is a patronym, most likely honoring a person with the surname Immelman who contributed to malacology or collected the type specimens. The original description does not provide an explicit dedication, so the exact individual is not confirmed.
Characteristics
- Shell morphology: The shell is conical, ranging in size from approximately 20 mm to 45 mm in length. It exhibits the characteristic high spire and narrow aperture of Conus species. Coloration patterns typically include a base of cream or light brown overlaid with darker axial or spiral markings; however, variation exists among specimens.
- Feeding and venom: As a predatory cone snail, C. immelmani employs a specialized radular tooth to deliver a complex venom cocktail to prey, which consists mainly of small marine worms (polychaetes). The venom components are peptides (conotoxins) of pharmacological interest.
- Human interactions: Live individuals are capable of “stinging” humans; envenomation may cause localized pain and swelling. Caution is advised when handling live specimens.

Note: While the existence of Conus immelmani is documented in malacological literature, detailed data on its precise distribution, population status, and ecological specifics are limited. Accurate information is not confirmed for several aspects of its biology and range.
