Seed when castor beans have been ingested by animals. In addition, seeds containing amygdalin—apple, apricot, bitter almond, peach, plum, cherry, quince, and others—when consumed in sufficient amounts, may cause cyanide poisoning. Other seeds that contain poisons include annona, cotton, custard apple, datura, uncooked durian, golden chain, horse-chestnut, larkspur, locoweed, lychee, nectarine, rambutan, rosary pea, sour sop, sugar apple, wisteria, and yew. The seeds of the strychnine tree are also poisonous, containing the poison strychnine. The seeds of many legumes, including the common bean ("Phaseolus vulgaris"), contain proteins called lectins which can cause gastric distress if the beans are eaten without cooking.
Golden poison frog semiopaca", "C. rugiceps" and "C. sp. A". Other related toxins, histrionicotoxin and pumiliotoxin, are found in frog species from the genus "Dendrobates". The golden poison frog, like most other poisonous frogs, stores its poison in skin glands. Due to their poison, the frogs are deterrent to predators; "P. terribilis" poison probably kills any predator, except for one snake species, "Liophis epinephelus". This snake may be resistant to the frog's poison, but is not immune (Myers & Daly, 1978). The poisonous frogs and birds themselves are perhaps the only creatures to be immune to this poison. Batrachotoxin attacks the sodium channels
