    Types of snakes in Costa Rica

    According to the research work of the ClodomiroPicado Institute, in the country snakes represent two thirds of reptiles.“11 families of snakes have been identified, of which only two are considered potentially lethal to humans.Thus, of the 140 species present in the Costa Rican territory, only 23 are considered poisonous,” say the experts.In addition, the authorities insist on the importance of not killing these animals, and even when there is a bite, it is not necessary to take the snake.


    Based on the symptoms and signs that the person presents, doctors can know the type of injury and the treatment that is needed.You can also use the word R-A-N-A (red-yellow-black-yellow) to identify the color pattern of corals, a poisonous species.

    “RANA” is an approximation that allows the non-specialist public to distinguish at least between the most common species of poisonous corals in the country and common species considered imitators.In addition, the acronym invites you to better inspect the found snake, this can contribute to its protection, if it can be recognized as harmless.

    What to do if you find them or have them as pets?

    According to the attention of the Fire Department, they can be found inside homes, ceilings, wardrobes, shoes and even those who have them as pets.That is why they recommend that whenever a situation with these reptiles arises, call 9-1-1 to request emergency help.

    “When we capture a snake that is not poisonous, a release is coordinated in a nearby area so as not to affect other ecosystems.While if it is a poisonous snake, the relocation is coordinated with the authorities of the Ministry of Environment and Energy (Minae),”explained the firefighter.Take into account that having a snake and simply releasing it can seriously affect ecosystems, as well as viruses and diseases.
