Golden poison dart frog

The golden poison dart frog is considered one of the most toxic animals on Earth. A single frog has enough venom to kill ten grown men. They range from less than an inch to two and a half inches in body length. These are more than 100 poison dart frog species living in the rainforests of Central and South America and on a few Hawaiian Islands. Poison dart frogs are so named because some Amerindian tribes have used their secretions to poison their darts.

They are bright in color, which can be yellow, orange, or pale green, depending on their particular range. The frog's color pattern is aposematic, which is a warning pigmentation to warn predators of its toxicity. The golden poison frog's skin is densely coated in alkaloid poison, one of a number of poisons common to dart frogs, which prevents nerves from transmitting impulses, leaving the muscles in an inactive state of contraction. This can lead to heart failure or fibrillation. Alkaloid batrachotoxins can be stored by frogs for years after the frog is deprived of a food-based source, and such toxins do not readily deteriorate, even when transferred to another surface. Chickens and dogs have died from contact with a paper towel on which a frog had walked.
