Generally we may only recognize these reptile beings in two terms, namely frogs and toads. In biological environments, the two terms are different, for example the species of Rana sp commonly referred to as frogs, whereas species like Buffo sp are referred to as frogs. The difference will be more obvious if you want to learn about reptile identification. But simply, the morphological character of the body determines both terms more.
This time the author would like to invite you to see frogs with a unique appearance. Their small, cute, and cute form, it keeps something that could endanger our lives. But they are not our threat, they are destined to produce poison, that ability is useful as a means of self-defense of predators in the wild. Let's see what they are.
Poison Dart Frog
Phyllobathes terribillis is the most toxic frog in the world, where the poison in its body has long been used by the inland tribes to smear their arrows before hunting. No living creature in this world can live for more than 10 minutes after swallowing this frog, except for a serpent type of Leimadhopis epinephelus, whose back is known to have special immunity to this frog poison. This type of snake L. epinephelus is the only natural enemies as well as controlling the populations of these frogs in the wild. Quoted from page blackchat31.com (accessed 28/01/2018), this frog lives in the tropics of Central America and South America. You should never try to eat it.
Yellow Frog
Diasporus citrinobapheus, quite rare found in tropical forests. But quoted from yukepo (accessed 1/28/2018), a biology researcher once encountered him in the plateau of Western Panama. Just like any other frog, the striking yellow color of the original habitat is a warning sign for anyone who wants to approach it. If you do not understand the sign, maybe death is near.
Poison Dark Frog
Just like P.terribillis, this frog lives in Central America and is used by rural tribes as a substance for smearing arrows in hunting. The frog, which has the scientific name of Amazonica ranitomeya, is small enough, its adult is only the size of a finger, but the poison is very deadly.
Asian Frog
This frog is commonly found in Vietnam, Cambodia, and Thailand. His ability to adapt to the new environment, causing the frog to be explosive in its population. Invasion of the toad named Latin Duttaphrynus melanostictus has even reached Madagascar. As quoted from the page bbc.com (accessed 28/01/2018), this toxic frog began to control several habitats and threaten the existence of native animals. The government of Madagascar has run a program for the extermination of the species in Madagascar, because in addition to endangering the native wildlife ecosystems, people who do not know about toads are toxic may eat them.
Andinobates opisthomelas
This frog contains a poison type Pumilotoxin A, this poison according to Myers, a biological researcher, could cause a rat to lose locomotorik control in the first minute, and die in the next eight minutes. And it's more or less the same effect if experienced by humans, although the duration of his death may be a little longer. Launched from the page dendrobates.org (accessed 28/01/2018), this frog can only be found in Colombia. With such an attractive color, this frog is a "walking poison" that can kill other animals at any time.
Most frogs live in the tropics, and most of the toxic ones do have flashing colors. They live in environments that have high humidity, low light intensity, and close to water and food. Given the frog is an aquatic animal, where some of its life cycle (tadpole) is in the waters, then this animal is also very sensitive to pollution, either pollution in waters or inland. Their existence can be used as a parameter to measure environmental quality.
