Drawings of Poisonous Shell Molluscs
Detailed in the drawing are Conus Marmoreus (Black and white shell - 'Marble Cone'), Conus Disambiguation (Red Shell - 'Textile Cone')
The marbled cone is a species of predatory sea snail, a marine gastropod mollusc in the family Conidae, the cone snails, cone shells or cones. This is a species which is believed to feed mostly on marine molluscs including other cone snails. This snail is venomous, like all cone snails, and occurs in the Indian Ocean off Chagos and Madagascar, in the Bay of Bengal off India, in the western part of the Pacific Ocean to Fiji and the Marshall Islands, and off Australi (Northern Territory, Queensland, Western Australia).
The textile cone shell has an irregular shingle-like pattern. It feeds on other molluscs which it immobilises by injecting a powerful venom with a harpoon-like tooth. The strength of this venom varies according to the type of prey the cone targets. Fish eaters have the strongest venom whereas those that eat worms do not need the same toxicity. Growing to 10 cm, the textile cone is highly dangerous to humans and should not be handled whatsoever. It is found in tropical waters of the Indo-west Pacific.
