Like other poison dart frogs, skin coloration is this frog’s protection mechanism, indicating its toxicity and telling predators to stay away. These tiny creatures show just how gentle they can be when it comes to their offspring. But their new research revealed the eggs are also spiked with alkaloids—the first time an animal has been found to pass on such chemical defenses to its offspring.

But “prior to this study, most of what we knew about alkaloids in these frogs came from adults. Thankfully, poison dart frogs are not toxic when raised in captivity because their poison is derived from their diet. Strawberry Poison Dart Frog Strawberry Poison Dart Frog Strawberry Poison Dart Frog; Did you Know? Researchers also tested whether the presence of these chemicals helped the tadpole defend itself. This explains that the frogs do indeed obtain some of the toxins through their natural diet (Davidson College, 2000; Kricher, 1997). Strawberry poison dart frog. A strawberry poison dart frog father checks up on his tadpole brood. With only 0.5 micrograms being a lethal dose on P. terrriblis has enough toxins to cause mortality in 20,000 mice.

One such amphibian disease is known as chytridiomycosis. Compared to P. terriblis, D. pumilio is close to harmless, at least for humans. This toxin has a negative stimulating effect on cardiac function and is a severe disruptor of the sodium potassium ion channels within cells. Although their eggs are laid among the leaves, the newly hatched larvae are carried on the backs of the parents to a pool of water or water-filled bromeliad. All of the tadpoles need their own water filled cavity, as mentioned before, due to the carnivorous habits of the tadpoles.

When these frogs are kept in captivity for research or for captive breeding it has been found that when these captive frogs are fed laboratory fruit flies the frogs will lose their toxicity over time. This type of “warning coloration” is called aposematism. If the climate would change, then the reproductive strategy of the frogs would either have to change or they would perish in a short time. An additional problem due to the level of maternal care is that the number of females that are available to mate decreases, so there is a higher level of male competition to mate with those females that are not attending to offspring (Prohl and Berke, 2001).
