Phylum: Mollusca, Class: Gastropoda, Order: Neogastropoda, Family: Conidae, Genus: Conus, Species: Conus textile · Conidae (Cone Snail family) · Gastropod (univalve), whole shell, cone-shaped
Species
Conus textile (Textile Cone)
Shell Type
Gastropod (univalve), whole shell, cone-shaped
Family
Conidae (Cone Snail family)
Size
Approximately 2.5 to 3 inches for the dominant Alphabet/Textile cone shown on the right, which is average for adult specimens. Adults typically range from 1.5 to 4 inches (40-100mm).
Color & Pattern
The prominent cone features a creamy-white or pale yellowish background overlaid with a complex tent-like network of golden-brown or dark brown markings, interspersed with distinct darker triangular or tented spots resembling ancient hieroglyphics or letters (hence 'Alphabet Cone'). Colors are natural and glossy.
Rarity
Common to Uncommon, frequently found by snorkelers and divers, though prized for its intricate patterns.
Habitat
Shallow tropical waters, coral reefs, intertidal zones to about 50 meters depth, hiding under coral rocks, rubble, or buried in fine sand during the day.
Geographic Range
Indo-Pacific region, spanning from the Red Sea and East Africa across the Indian Ocean to Polynesia and the Hawaiian Islands.
Description
A classic cylindrical-to-conical gastropod shell featuring a low, flat spire and a narrow, elongated aperture running nearly the entire length of the shell. The outer surface is smooth, highly polished, and displays an intricate tent-like or letter-like pattern that gives the species its common names. The other accompanying shells in the display include a bubble shell or small moon snail variant and a small whelk or dove shell displaying spotted patterns.
Key Features
Inverted cone shape (turbinate to cylindrical), low spire, narrow aperture, and the distinctive tent-like or letter-like brown markings over a light background. Note: Live cone snails possess a highly toxic venom apparatus, though empty collected shells lack the animal.
Collector Value
Highly desirable for shell collectors worldwide due to its striking geometric patterns. Common specimens are affordable (a few dollars), but large, flawless, or rare geographic color morphs command higher prices.
Condition Notes
Specimen is in excellent 'Gem' to 'Fine' condition with glossy surface luster, intact outer lips, minimal wear, and natural coloration preserved without significant bleaching.
Interesting Facts
Cone snails are predatory marine gastropods that use a modified, harpoon-like radular tooth delivering a potent neurotoxic venom to paralyze prey such as fish, worms, or other mollusks. The Textile Cone's venom is extremely potent and has caused human fatalities; live specimens should never be handled bare-handed.
Ecological Role
Apex invertebrate predators in coral reef ecosystems, helping maintain the balance of reef biodiversity by preying on marine worms and small fish. Due to their venom, they have few natural predators.
Similar Species
Conus archiepiscopus (Bishop's Cone) and Conus ammiralis (Admiral Cone), which feature different arrangements of tents, bands, and geometric markings.
Beach Finding Tips
Best found by snorkeling or scuba diving around coral reefs and sand pockets at low tide. Empty shells can occasionally be found washed up in shell drift or inhabited by hermit crabs.
