What has venom that can cause paralysis nausea breathing difficulties and death in people?

Poison arrow frogs secrete a venom through their skin that can cause paralysis, nausea, breathing difficulties, and death in people. It is believed to be a lipophilic alkaloid toxin that does the most damage. Poison arrow frogs sequester their poisons from their food (such as ants). If not raised on poisonous insects, they will not secrete poisons from their skins.
