Which group of toxins is derived from animal sources?

Animal venoms are indeed the correct choice when identifying a group of toxins that are derived specifically from animal sources. Venoms are biological substances produced by certain species of animals such as snakes, spiders, scorpions, and some marine creatures, and they are often used for predation or defense. The unique chemistry of these venoms allows them to immobilize or kill other organisms, as they typically contain a complex mix of proteins, enzymes, and other molecules that can provoke a range of physiological effects in the victim.

In contrast, mycotoxins are toxins produced by fungi and are not derived from animals. Plant toxins originate from various plants and have different modes of action, impacting both herbivores and humans in various ways. Algal toxins are produced by certain species of algae and can contaminate water and seafood, leading to harmful effects in marine life and humans. Each of these groups is distinct in origin and behavior, firmly placing animal venoms squarely in the realm of toxins derived from animal sources.
