The danger exists in the form of the weaver fish, whose (PAINFUL) sting can cause potentially fatal allergic (REACTIONS) in young children and can further (WEAKEN) the heart of an elderly person. When the weaver fish uses its sting, it is not behaving (AGGRESSIVELY) but merely acting defensively since the (SIGHT) of a large foot descending is perceived as a threat. (FORTUNATELY) for the majority, the sting can be easily treated by soaking it in hot water.
