What part of poison dart frogs shows the greatest parental care?

In poison dart frogs, it is primarily the females that demonstrate the greatest level of parental care. After mating, the female lays eggs, usually on leaves or in water. This species is known for its unique parenting behavior, where the female not only lays the eggs but also often plays a crucial role in keeping them moist and safe from predators until they hatch.

Once the eggs hatch, the female may then transport the tadpoles to different water sources, such as small pools in plants, where they can continue to develop. This nurturing behavior showcases a significant investment from the female in ensuring the survival of her offspring. While males in some species of frog may assist in guarding the eggs or even calling to attract mates, in the case of poison dart frogs, it is the females who take the lead in parental care. This trait makes it clear that female poison dart frogs play a critical role in the early development of their young, underscoring the levels of maternal involvement seen in this species.
