By observing different poisonous frogs we can discover that most have lit and vibrant colors. This is known as APOSEMATICSand has the function of warning its predators who are very toxic if they are eaten. The majority of alkaloid poison frogs belong to the family of toxic leather dendrobatids, but there are few other species that are also poisonous. If you would like to know some of them, we invite you to read this ecology article about the different Types of poisonous frogs and how they attack.
Yellow and black dendrobate (leukome dendrobates)
Most of the Dendrobatid frogswhich are commonly called poisonous frogs or frog rugdo not produce their own poison, but They are synthesized from its food.
In the case of this species, he obtains it from ants that are the basis of their diet. The poison is distributed to your skin. Therefore, if these frogs are not fed with ants, your skin will not be poisonous.
We recommend this other post about the difference between toad and frog.
Golden poison frog (phyllobates terribilis)
It is the dendrobate or frog more poisonous arrow that exists. Some also consider it the most dangerous vertebrate in the world.
He lives on the Pacific coast of Colombia, and his poison is composed of batracotoxin, batracotoxin A and homobatracotoxin that They cause respiratory arrest. The poison They get it from ants Brachymyrmex spp. and Paratrechine spp. The natives used the poison of these frogs to cover your arrow tips to annihilate his enemies.
Phyllobates vittatus
Although it is the least poisonous species of Phyllobatesit has a very strong effect on who threatens them. Can Cause seizures and even paralysis. Measures 3.5 centimeters long and considerably Great among all poisonous frogsso you can store a lot of poison in your skin.
Has one of the more striking patterns Among the poisonous frogs: it is black that seems to have shiny, with turquoise blue legs and two orange, yellow or green lines that run through the body vertically.
Golden tablecloth (aurantiaca tablecloth)
This is one of the poisonous frogs that does not belong to the dendrobatids, but belongs to the family Tablellidae.
Inhabits Madagascar, and is a ignition Orange yellow color that warns his predators that he is dangerous. It is very small, 2 to 3 centimeters long. Your secret skin alkaloid toxins that come from ants.
Mimetic dendrobate (Ranitomeya imitator)
Although this frog is poisonous, use Müllerian mimicry to copy the patterns and colors of other species of poisonous frogs to confuse and protect yourself from predators.
We recommend you read this other ecology article about mimicry: what is and examples.
Rana Cohete (Colostethus spp.)
These frogs live in regions of Panama and northwest of South America, to northern Peru. What can attract more attention to this frog is that special because despite being a poisonous dendrobatide, It does not exhibit an aponymatic coloration. It is completely brown or brownwith a beige line to the side.
Blue arrow frog (azureus dendrobates)
This dendrobatide lives in Brazil and Suriname. It is one Vibrant blue king with black motorcyclesalthough between populations the color may vary slightly purple. They measure 4 to 5 centimeters long It feeds on ants and from here obtains the formic acid which will be located in your skin by turning it one of the best -known poison or toxic frogs.
Arborícola frog (Aparasphenodon Brunoi)
This frog has thorns on the edge of the skull with those that hit the possible predators to pierce and inject a poison that comes from glands connected to these thorns. Unlike the other frogs we review, this does have the ability to synthesize your own poison. The poison is 25 more toxic and lethal than that of gender venomous snakes Bothrops Among which are the cantiles, nauyacas and bells.
Arborícola frog (chorythomantis Greeningi)
Like the previous species, it also has poisonous spines in the skull. These have larger poison glands and thorns, but with less toxic poison than A. Brunoibut being 2 times stronger than snakes Bothrops. It is one of the few truly poisonous frogs, because They manufacture their poisonand do not get it from food.
Rana corroboratee (pseudophryne corrobooree)
This is a poisonous frog native to Australia and Tasmaniawhich is also special because can synthesize your own poison. They are frogs Black with many bright yellow curved lines. The alkaloid poison is unique and is called pseudophrinamine, referring to the scientific name of the frog. This poison is secreted through the skin, and although it has a function against predators, it has also been suggested that it serves to combat possible infections, to which the anuro are extremely prone.
How they attack poisonous frogs
Poisonous frogs do not attack because yes, in fact they do not usually attack how they could think. They will only use their poison to defend against threatsthey do not use it to obtain their prey. They are very territorial animals, so you should not enter their space or disturb their rebirth. In this behavior, persecutions or struggles can be seen.
Your attack method is quite simple: Anyone who touches a poisonous frog will die or will be seriouswithout the need for her to enter. This is because the poison is distributed throughout the skin, except for the two already mentioned cases of Corythomantis Greeningi and Aparasphenodon Brunoiwho give stops or Head blows To puncture and inject poison.
