Dendrobates tinctorius, also known by the common name dyeing dart frog, is a species of poison dart frog. It is the largest species, reaching lengths of 50 millimetres.

This estimate will vary in turn, but most agree that this dose is enough to kill between 10 and 20 humans, which correlates to up to two African bull elephants. This is roughly 15,000 humans per gram.tion. This can lead to heart failure or fibrillation
