    First aid treatment for the venom requires pressure on the wound and artificial respiration once the paralysis has disabled the victim's respiratory muscles, which often happens minutes after being bitten. Tetrodotoxin causes severe and often total body paralysis. The victim remains conscious and alert. This effect is temporary and will fade over a period of hours as the tetrodotoxin is metabolized and excreted by the body. It is essential that rescue breathing be continued without pause until the paralysis subsides and the victim regains the ability to breathe on their own. Using a bag valve mask respirator reduces fatigue to sustainable levels until an ambulance can arrive.
    Professional hospital treatment involves placing the patient on a ventilator until the toxin is neutralized by the body. The symptoms vary in severity; children tend to be high-risk due to their smaller body size. Due to the venom primarily killing through paralysis, victims are frequently saved if artificial respiration is started and maintained before cyanosis and hypotension develop. Victims who live through the first 24 hours generally fully recover.

    PHYLUM MOLLUSCA
    ...
    been described.
    Although most mollusks are marine, many snails and clams live in fresh water, and some species of snails and slugs inhabit the land. According to past research, mollusks probably evolved early in the history of the protostomes, soon after the evolution of the coelom but before the origin of the segmented body that is characteristic of annelids and arthropods. Most mollusks share certain basic characteristics, although mollusks vary widely in outward appearance. Molluscs are highly diverse, not only in size and in anatomical structure, but also in behavior and in habitat. Molluscs have such a varied range of body structures that it is difficult to find defining characteristics that apply to all modern groups. The two most universal features are a mantle with a significant cavity used for breathing and excretion and the structure of the nervous system. The "generalized" mollusk's feeding system consists of a rasping "tongue" called a radula and a complex digestive system in which exuded mucus and microscopic, muscle-powered "hairs" called cilia play various important roles. The brain, in species that have one, encircles the esophagus. Most mollusks have eyes, and all have sensors that detect chemicals, vibrations and touch. A striking feature of mollusks is the use of the same organ for multiple functions.

    Niche: It serves as prey for crustaceans, fish and some birds. Several European countries partake in the farming of these creatures for food. Other than getting eaten, it can acquire food by filtering water when it opens and closes its shell. Plankton are its main source of food.
    Reproduction: Clams reproduce by spawning, releasing sperm and eggs into the water to fertilize each other. This happens generally in the mid-summer when plankton is abundant. Some have been recorded as reaching 60 million eggs spawned in one season. Spawning can last for months continuously. The larvae is produced after cellular divisions that occur. Interestingly enough, they are capable of changing gender with age, but that will happen later as they mature. As larvae, they swim towards light and concentrate on the surface. Eventually, after metamorphosis into the juvenile stage, it sinks back to the water's floor and secretes a calcium carbonate shell when it digs into the mud with its foot.
