![]() The venom of the textile shell is very toxic and the sting is known to have caused human fatalities. When it finds something, it begins to approach. It takes water in through its siphon and tastes it, seeking out the aroma of prey. Behaviorįollow this link to additional information about cone snails. The Cone Snail wanders around on the sea floor. At this time they are about 1.5 mm (0.06 in) in length. The larvae remain pelagic for about 16 days, then settle onto substrate. The few eggs that survive to hatch do so in about 16 to 17 days. Cone snails incapacitate their prey by injecting a cocktail of neurotoxins, which can be dangerous to humans. The textile cone’s egg capsules contain 500-700 eggs each The capsules are laid under rocks. It is known to be cannibalistic if other food is scarce. This cone is a molluscivore, a mollusk eater. The average length of these animals is 9.0 cm (3.5 in). The background color is some variation of white or bluish white, with light to dark brown or yellowish overlapping textile markings, and three yellowish or brown interrupted spiral bands. The color and pattern of this beautiful cone is highly variable. There are slight spiral ridges near the base of the shell, and the rest is smooth. The body whorl is convex with rounded or slightly angled shoulders. This marine cone snail has a highly glossy, heavy shell and a short spine with straight or slightly concave sides. The textile cone lives in the sand beneath coral and rocks in shallow waters. Throughout the Indo-Pacific region, Australia, and the Indian Ocean from eastern Africa to Hawaii and French Polynesia. Using high-speed videography, the researchers determined that the radular harpoon can be propelled into prey within 100 microseconds, with a peak acceleration exceeding 280,000 m/s2 and a maximal acceleration exceeding 400,000 m/s2. This species is not currently on exhibit at the Aquarium. The Textile Cone Snail is one of the most venomous creatures in the sea, in fact it produces some of the most toxic substances known to man, and their sting contains enough venom to kill up to 20 humans There is no anti venom and a sting from this scary creature could kill you within a few minutes. Cone snails have one of the quickest strikes in the animal kingdom. "It is a pretty deadly venom and if you're unlucky enough to have a decent amount injected then potentially the consequences could be fatal.CLIMATE CHANGE: Not Applicable At the Aquarium "The fatal dose of the venom could be as little as two milligrams for a 70 kilogram adult so that's comparable sort of toxicity to what you get with some snakes," he said. In the case of the tour crew member, Dr Craik said the venom would have blocked his nerve impulses that control muscles associated with breathing. The venom is designed to paralyse, however not much is needed for it to kill fish, or humans. The cone snail has a proboscis that hangs out like a lure to attract fish, which are then harpooned.Īt the end of the proboscis they have a hollow tooth, through which the venom is injected. They eat marine worms, small fish and even other cone snailsĪside from the pain, cone snail's venom can, in severe cases, cause muscle paralysis, vision impairment, respiratory failure, and can be fatal.įew know its full effect with just 36 people dying from the unassuming killer in the past 90 years, University of Queensland chemistry professor David Craik said. ![]()
