    Angry Arghhh - Anyone help?

    It looks like I have been sent 30 Conus snails by mistake. I will know tomorrow. I am looking to get my money back on these or possibly just find them a home for free, but as you will obviously know these are a dedicated species snail. Not one for the novice due to the venom harpoon. If anyone could possibly be intrested in these - PLEASE PM ME!

    Jeezo, watch it James. Sorry but I can't help, those things are lethal.

    Public aquarium/research centre maybe?

    Anyone - Any ideas?

    I am absolutely disgusted with this.

    1. I never asked for these snails and never would.
    2. I was sent these as a replacement for Trochus snails :confused:
    3. These deadly snails are actually listed as turbo snails from the supplier :eek: but due to the scientific name I know what they are.

    I DONT EVEN WANT TO OPEN THE BAGS;

    I dont know how toxic this species is but know in general not to go near a cone snail. Can anyone help as I dont want to be cruel and just let them die in the bag and dispose of.

    Is there a specialist aquarist / zoo / lfs that could help me here :confused:

    James

    ps Things like this make me what to call it a day in this business.

    James,

    I have contacted Deepsea World in Edinburgh. Don't know how long they'll take to reply but I have sent them your email address as well as a the text and a link to this thread.

    Can't help James but in case anybody's wondering what the fuss is about....

    Cut&paste


    The layman may simply feel them as cute, whereas the, he collector admires the very variant-rich, filigree colour reviews of the porcelain like shells of the cone snail-snails.

    Different brighter basic colourings and multi-faceted variant-rich drawings with mostly brown and black grids, stripes, spots, spots or shadings make it not easy even for experts to determine the different species. Furthermore cone snails in free nature are often encrusted with algae or moss or buried also in the sand, facts which do not facilitate the identification Worldwide there are supposed to be more than 500 species of cone-snails. Roughly half of the species is to be encountered in the intertidal waters of the Philippines - and here in particular on Bohol and Cebu.

    With respect to rarity, price position and maybe also beauty the "Gloria Maris” has the highest rank. The gold-brown shell has a fine net drawing and reaches a length of up to 15 centimetres. In the 18th and 19th century the “Gloria Maris” was for collectors a distinct rarity. It was already a sensation when in 1838 three specimens were detected on the Philippines. In the meantime there are more findings, the price is still remarkable. Shells of “Gloria Maris” are offered in the Internet-market from 200 US$ upwards.

    But here we don’t want to refer to the beauty of cone snails but to her potential danger. In doing this we have to look for the physique and the hunting behaviours of the snails.

    Body and injection mechanism



    The basic form of the cone snail shells is to a large extent identical: a regular, straight-sided conical shape with a tapering body whorl and a quite flat, sometimes bumpy spire and an oblong, slot-shaped aperture.


    At the narrow side of the shell you can see a little rounded aperture, from which a siphon (breath tube) can be extended. With help of the siphon oxygenous water can be transported into the gills even when the shell is buried in the sand. The siphon has chemo receptors indicating the neighbourhood of possible prey. The snail can withdraw her foot into the shell. In the interior of the shell we find the viscera sack and other inner organs like liver, lung, and kidneys. A thin mantle covers the body and lines the inside of the shell.

    Cone snails have a longer muscular foot which is used for the slow, wavelike moving. The foot carries on the back the dagger-like operculum on the back side (broader side of the shell. In case of a withdrawal of the snail the operculum locks the access. In the foot there is an organ of equilibrium and localisation. It is filled with bubbles, which contain calcium-carbonate-granules. The pressure of the granules is transmitted to nerves cells. On the narrower side of the shell the foot, which has a lot of mucous glands, merges into the head. The head has eyes and two tentacles as sense for touch.

    Let's now come to the most significant organ of the cone snail, the distensible snout (proboscis). Often only the proboscis looks out of the sand and imitates a worm. Conus snails are nocturnal predatory animals, that pursue other molluscs, worms, small fishes or the own family. During evolution they changed their radula teeth into little hollow poison-filled “harpoons”, which are provided with barbs and can reach a length of one centimetre. The harpoons are in a kind of sack and each of them is connected with a poison gland. They are exchangeable and can be recharged by reserve harpoons. A special muscle is able to shoot the poison harpoon in the direction of the prey. Often the death of the prey occurs within seconds after the injection of the poison cocktail. The poison harpoon is shot with a thread. So the cone snail remains tethered with the prey. After having trailed the paralyzed prey to its snout and the snail extends the proboscis like a snake. It envelops the prey, which can reach the own size and the digestion is beginning. The poisonous darts are also used for own defense.

    There is only a small knowledge about the life-cycle of the cone snails. In a opened capsule of a "Conus textile!" have been found 500 - 700 eggs. We can suppose that only very few reach an adult stage.

    Encountering cone snails





    Cone snails can be found in the reef and coastal areas especially in time of low tide. In principle, all species can inject poison. But the poison dose of the large majority of the round about 500 species is too weak to endanger man. Such snails that feed on worms have the weakest poison. Dangerous for man however are the larger species which are hunting small fishes (piscivorous species). They can cause strong pains and their toxins can be lethal also for humans. Special care is necessary with regard to the

    l "Conus geographus", which is classified as most dangerous because of its very strong venom cocktail. Its shell shows map-like markings. Sometimes it is also called “cigarette-snail” because it is told that after the stitch there is only the time to smoke a cigarette before passing away. Hanewald is writing that in the Philippines all certified deaths are caused by this sea snail.(1)

    l "Conus textile" with a pointed spire, white background and many small and large overlapping angle signs. There is another author writing that at least two deaths have been associated with the “conus textile” stitch(2).

    l "Conus striatus": Shell with fine spirals-lines

    l “Conus aulicus", which can be found in particular on Samar

    l and the thin shaped "Conus tulipa" ,which has a broader shoulder ramp

    The puncture mark is often very small, deep and three-angled. The descriptions of the physical conditions after the ***** differ a little bit because the cocktail of venom peptides can have both inhibitoric paralyzing and excitatory cramping effects depending on which muscle nerves have been targeted. In this context we should mention again, that many encounters cause pains for some hours, but not run fatally.

    The following symptoms have been described:

    At first very short-run swelling and vehement pains in the place of puncture

    Locale and/or generalizing deafness

    Nausea, dizziness, eye-defects

    Weakness, paralytic symptoms in the extremities

    Flat breath, weak pulse, unconsciousness

    Breath paralysis, coma, death (in a described case after five hours)

    Which precautions should be taken? If one finds cone snails in the reef, caution is necessary. Also for specialists it is difficult to distinguish the dangerous snails from the harmless ones. Even the same species can vary to a certain degree with regard to its external appearance. If the wish for collecting prevails, than it is recommended to hold the animal on the widest point. The use of tongs is better. And never put the living animal into your trouser pocket.

    In case of sting-injection there are no specific emergency measures and no antidote exists. A general help could be: ligature of the affected limb, the immersion of the limb into very cold or very hot water, artificial respiration in case of respiratory paralysis and immediate medical consultation.

    Cone snail poisons in the focus of the drug research

    It was in particular the Philippine biochemist and neurologist Baldomero Olivera, who began in the late sixties to analyse the complex poison cocktail especially from the species "Conus geographus". His goal was the fractioning and synthesizing of the peptides and conotoxins in order to get better drugs. Why synthesizing? That’s because the natural stock of conus snails would have never sufficed to produce adequate quantities of drugs. And no one could justify such a severe intervention into the biotopes.

    The analysis showed astonishing results. Every species of cone snail has a complex of about 100-200 poison peptides. They differ from species to species, so an enormous depot of different peptides could be screened. In the meantime researchers isolated a sequence of more than 1000 toxins and round about hundred toxins have been manufactured chemically. Especially the neurotoxin SNX 111, which is in clinical investigation stage III, raises hopes. It is as painkiller, which is thousand times stronger than morphine, but it has not the side effects of morphine (drug addiction and tolerance development). It could be used in treatment of chronic pains the final stage of cancer and Aids. Now many other pharmaceutical laboratories research further possible applications (i.e. treatment of mental illnesses and neurodegenerative diseases).

    It seems that till now the highly effective poison peptides have not found entry into the production of bio weapons. Nevertheless Gary Stix (3) reports that the Russian military in time before president Jelzin tried to insert a fatal poison peptide of the "Conus geographus" into a small pocks virus. The experiments are supposed to have been unsuccessful, but underline the enormous poison potential of some cone snails.
    .
    kids, if you drive down the road with your windows open, music blaring and you think you look cool.....

    Just remember, everybody looking at you is thinking "what a pratt" and laughing at you.

    I have sent a very strong letter to the agent that brings these into the country. I have explained to him that most LFS do not know scientific names and to be told this is a turbo is wrong and dangerous. I have also asked for these snails to be removed by DEFRA and dispossed off if a home cannot be found. I dont want to personally touch these snails and feel really ANGRY about the whole situation. I await their reply but to be honest the shipper should be held accountable, not the agent. Imagine if someone was stung by this cone snail and died!! After a LFS sold him it as a harmless turbo snail. Who would be made you blame? The supplier, Agent or your LFS? I shudder to think how many of these snails have already been sold to the hobbyist as a turbo snail.

    James

    PS There is a very slight possibility the shipper has put down the wrong scientific name but the agent thinks the common name 'Turbo Snail' is wrong!

    Thanks EM for the link, intresting reading. The species (CONUS MARMOREUS) is not on the most dangerous but as the author says they are hard to tell apart from the ones that have killed man to date. The other thing that is worrying is there is no antedote (sp).

    I have done a search on google for CONUS MARMOREUS but cannot find out how toxic its venom is. I know from an article it is stronger than Morphine (sp).

    The other thing that is also very wrong, imagine putting this snail into your reef as it is being sold as a turbo. Ist of all it is a carnivore and second of all its a preying carnivore!
