ABSTRACT
Fish toxins are of two types: the small, molecular oral biotoxins that are poisonous to eat, and the large molecular venoms that are injected into the body by means of a specialized device known as the venom apparatus. Thus all venoms are poisons, but not all poisons are venoms. In this chapter, only the oral biotoxins are discussed in regard to the names of the transvectors, their geographical distribution, clinical characteristics, and a brief statement of the toxin involved.
