As a herpetologist with a keen interest in the study of amphibians, I am often asked about the toxicity of various species, including toads and their tadpoles. The question of whether toad tadpoles are poisonous is particularly intriguing and warrants a detailed examination.
Toad tadpoles, like many other amphibian larvae, undergo a metamorphosis as they develop into adults. This process involves a series of physiological and morphological changes that are crucial for their survival and adaptation to different environments. During this stage, their primary concern is growth and development, and they are generally not equipped with the same defensive mechanisms as their adult counterparts.
However, it is essential to understand that the term "poisonous" can be misleading when applied to animals. In the context of toads, the term is often used interchangeably with "venomous," which refers to the ability of an animal to produce and deliver toxins through specialized organs or mechanisms. The Cane Toad, *Rhinella marina*, is a well-known example of a venomous toad. It possesses large, prominent parotoid glands that secrete a potent toxin when the toad is threatened or handled roughly.
The key distinction here is that while adult Cane Toads are undoubtedly venomous, their tadpoles are not typically considered poisonous in the same sense. The parotoid glands are not fully developed in tadpoles and do not contain the same level of toxins as those found in adult toads. However, it is important to note that the water in which Cane Toad tadpoles are found can sometimes contain traces of their toxins, especially if the tadpoles are in a stressed state or if many are present in a confined space.
It is also worth mentioning that the Cane Toad's life cycle includes several stages, each with its own set of characteristics and behaviors. The eggs, which are laid in long strings and encased in a gelatinous substance, are not known to be toxic. Tadpoles, as mentioned, lack the developed venom glands but can still pose a risk if ingested by predators, as some of the toxins may be present in their bodies. Toadlets, or juvenile toads, begin to develop their parotoid glands, but they are not as potent as those of adults. Finally, adult toads are the most venomous, with the capability to cause harm or even death to potential predators through their toxins.
In conclusion, while Cane Toad tadpoles are not poisonous in the traditional sense, they are part of a life cycle that includes venomous stages. It is crucial to approach all stages of amphibian life with caution, especially when handling or encountering them in the wild. The potential for toxins to be present, even in the larval stages, should not be underestimated.

All stages of the Cane Toad's life cycle: eggs, tadpoles, toadlets and adult toads, are poisonous. Cane Toads have venom-secreting poison glands (known as parotoid glands) or swellings on each shoulder where poison is released when they are threatened.
