toxicfrogs

Toxic frogs are very beautiful. Very colourful. And they have great coping mechanisms. Rather than leaving a toxic environment, they stay and turn poisonous themselves. Their bodies learn to cope with their sickening environment. For humans it can be very useful too. Their way of dealing with toxic material can teach us how to make medicins for similar toxicity.

It shows the surviving skills of frogs.  These are the frogs that stay. Even in boiling water. Even in highly toxic habitats. Their body can hold enough poison to kill ten human beings. When they are on captivity diet, their toxicity rapidly decreases.

One of the most toxic frogs is the golden poison frog. Its skin is densely coated in alkaloid toxins, Batrachotoxin, homobatrachotoxin. It is stored in its glands. The toxin attacks the amount of sodium in the nerve cells of the pray. It leads to irreversible damage, causing arythmia and heart failure in its pray. That is how the frog paralyzes its victims. The frog itself can handle that. Scientists are looking for ways to use the poison as an anaesthetic.

Nonetheless even those survivor frogs are threatened with extinction due to the rapidly decreasing rainforest. Though they are frequent in the areas that they are known to reside, those areas are not under any protection. That’s why the golden poison frog is on the red list.
