Summary[edit] Description: Conus excelsus Sowerby, 1908 - excelsior cone snail shell (abapertural view), modern (latest Holocene). (public display, Bailey-Matthews Shell Museum, Sanibel Island, Florida, USA) The gastropods (snails & slugs) are a group of molluscs that occupy marine, freshwater, and terrestrial environments. Most gastropods have a calcareous external shell (the snails). Some lack a shell completely, or have reduced internal shells (the slugs & sea slugs & pteropods). Most members of the Gastropoda are marine. Most marine snails are herbivores (algae grazers) or predators/carnivores. The conid gastropods (cone shells) are fascinating marine snails for a couple reasons - they have attractively-shaped, colorful shells and they are killers. The conids are predatory, as are many other marine snails, but they take down their prey in an unusual fashion. The radula of most snails is a mineralized or heavily sclerotized mass of small teeth that scrapes across a substrate during feeding. Conid snails have a toxoglossate radula - one that has been evolutionarily modified into tiny, unattached, toxin-bearing, harpoon-like darts (see photo - science.naturkundemuseum-bw.de/files/images/niederhofer_2..) that can be fired at prey. Each dart is an individual tooth. The nickname "killer snails" is well deserved (even people have been killed). Some species have incredibly powerful toxins, while in other species the toxin has little effect on humans.

Summary[edit] Description: English: Illustrations taken from the original text of the discovery of Conus excelsus, by G. B. Sowerby III, in 1908ː "Description of a new Species of the Genus Conus"; published in the Annals and Magazine of Natural History, series. 1. pp. 465-466. Top and side view, with the outer lip facing the viewer. Text by the author about the specimen (long. 93, maj. diam. 33 mm.): "Hab. New Caledonia? This magnificent shell, at present unique, defies comparison with any hitherto known species. The most proeminent feature is the extraordinary height of its acutely conical spire, which is quite symmetrical and has no appearance of abnormality. The whorls are angular, a little concave above the angle, with two shallow spiral grooves; the first eight or nine are coronated with minute tubercles at the angle. The body-whorl is gracefully attenuated towards the base and slightly rounded at the angle, which is surmounted by a narrow keel. The surface is sculptured by rather numerous shallow spiral grooves and longitudinal minute irregular plicæ. In colour it is rather light fulvous yellow, with white patches of various sizes and shapes, outlined with reddish brown; the brown flames and white spaces on the upper part of the body-whorl and crossing the angle have the obliquely arcuate form of the labial sinus. The aperture is of about the average width, with a thin sharp lip arcuately receding and forming quite a Pleurotomoid sinus. The shell came to me from New Caledonia; but I have at present no certain information as to its habitat. It is now in the British Museum (South Kensington)". According to the book cited below Conus excelsus G. B. Sowerby III, 1908[1] is a rare species in the offshore waters from Western Pacific. ABBOTT, R. Tucker; DANCE, S. Peter (1982).
