Conium maculatum the difficulty in associating malformations with the much earlier maternal poisoning. Since no specific antidote is available, prevention is the only way to deal with the production losses caused by the plant.

Poison dart frog by the relatively large size and high levels of toxicity of its members. Most species of poison dart frogs are small, sometimes less than in adult length, although a few grow up to in length. They weigh 1 oz. on average. Most poison dart frogs are brightly colored, displaying aposematic patterns to warn potential predators. Their bright coloration is associated with their toxicity and levels of alkaloids. For example, frogs of the genus "Dendrobates" have high levels of alkaloids, whereas "Colostethus" species are cryptically colored and are not toxic. Poison dart frogs are an example of an aposematic organism. Their
