A cone snail sting has been reported in various countries particularly in the Pacific and Indian Oceans, Caribbean and along the coast of Florida. Cone snails have a cone-shaped shell with a fleshy foot, tentacles and a head. Even though not aggressive, a cone snail sting typically occurs among divers who venture in deep reef waters who handle snails.
The shells of cone snails span in length from less than an inch up to 9 inches. The snail uncoils itself in the shell and emerges out of the opening. Similar to a harpoon, the sharp poisonous stinger stabs on a prey.
It is vital to avoid touching the snails since its harpoon can pierce through gloves. The toxin is comparable to the paralytic toxin of the blue-ringed octopus and pufferfish.
Indications of a cone snail sting
The symptoms usually start within minutes or even take days to manifest such as the following:
- Intense pain
- Tingling sensation
- Numbness
In severe cases of stings, it involves blurry or double vision, muscular paralysis and respiratory paralysis which results to death.
Management
- Submerge the area with the cone snail sting in hot water that the individual can tolerate.
- Utilize the pressure-immobilization technique. The affected extremity is wrapped with a bandage similar to a sprained ankle. Firmly bind the limb but not too much that the circulation is disrupted.
- Instruct the individual to avoid movement.
- In some cases, CPR might be required. Artificial respiration can help save the life of an individual.
- Avoid cutting into the wound, use suction or a tourniquet.
When to seek medical care
It is vital to seek medical care as soon as possible. Remember that there is a possibility that intensive care in a healthcare facility might be required which can include a respirator.
