What clinical sign is NOT associated with Bufo marinus/Rhinella marina poisoning?

Bufo marinus, also known as the cane toad, produces potent toxins that can lead to a variety of clinical signs in animals, particularly if they attempt to ingest or come into contact with the toad. Common symptoms of poisoning include hypersalivation, ataxia, and cyanosis.

Hypersalivation occurs as the body's response to the irritants and toxins from the toad, leading to excessive drooling. Ataxia, a lack of coordination, often results from the neurotoxic effects of the toxins on the central nervous system. Cyanosis, which is a bluish discoloration of the skin or mucous membranes, can occur due to the impairment of oxygenation resulting from the cardiovascular effects of the toxin.

In contrast, increased appetite is not a clinical sign associated with Bufo marinus poisoning. Typically, poisonings such as this one would lead to a decreased interest in food or an outright refusal to eat due to illness and discomfort from the toxic effects. Therefore, the clinical sign that does not correlate with poisoning from Bufo marinus is increased appetite, making it the correct answer in this context.
