Are There Dangerous Or Poisonous Animals In The Dominican Republic?

The Dominican Republic does not represent a danger of consideration for human beings when they come into contact with nature. But this does not mean that there are no poisonous animals in the Dominican Republic.

Poisonous doesn’t mean it’s lethal, but it can mean very painful. A sting can be complicated by various conditions and even represent death, such as a severe allergic reaction or anaphylactic shock, even from a bee sting.

In the Dominican Republic, there are no lethal poisonous animals, but the bite of some is very annoying and can lead to complications to very sensitive people, scorpions, tarantula, nor the black widow in our territory are not a threat to man, his toxin It is only high for small animals and insects.

The venom fatalities of some species depend more on lack of treatment or complications, such as the bite of some endemic spiders. The sting of the thorn line is one of the most painful on the beach, it uses its stinger when it is stepped on. A poison that can last for hours, causes intense pain and drifts through the body.

I must specify, for those who have never visited the Dominican Republic, these animals mentioned in this topic are not abundant in all parts of the country, in fact, in all my life living in the Dominican Republic I have never seen a scorpion, but they exist in a certain area of the island.

I have only seen the Solenodon in photos for example, those that I have been able to witness in trips to rural communities have been the Huron, the Jején, and in Puerto Plata I was able to see a stingray many years ago.

According to some research that I made; these are the most dangerous animals in the Dominican Republic.

 

sea urchin

I must say that this was the creature that I most feared as a child and went to the beach, is usually found on the beaches of Boca Chica and Juan Dolio, near Santo Domingo.

Sea urchins are lined with large sharp spines, sharp and sometimes coated with poison. Touching or stepping on those sharp spines usually causes a stabbing and painful wound. The spines break frequently in the skin and cause chronic pain and inflammation when they are not removed.

Sea urchins are not found on the coast or in the bathing area of the beach, but rather in some rocky areas of the beach.

Phlebotomus papatasi (Jején)

no-see-ums Dominican Republic

The Jején is also known as the black fly, although it can be black or grey. It is a very small insect, no bigger than the head of a pin at most 2 to 3 mm. They can be found anywhere in the world where there are rivers or streams, because they lay their eggs in places with water. They need the blood of warm-blooded animals to survive. They can sting people through their clothes to get blood.

The natives in the Dominican Republic call this insect “maye”

A person may not immediately realize that he has been stung by a Jején. But soon after, the area of the bite will start to swell. A little bit of blood may come out of the bite. It will be very itchy and may be painful. This insect is not poisonous, but its sting could result in serious problems for allergic people, it could also be a source of transmission of parasites.

Cassiopeia is also known as inverted jellyfish, marine jellyfish are pelagic, jelly-shaped in the form of an umbrella or bell. Regularly found in mangroves and deep in shallow water, their bite can go unnoticed as a simple discomfort in the skin that soon disappears. In contrast, jellyfish species with tentacles, their toxicity in the bite can vary depending on the species. The bite can be painful with a brief burning sensation.

Most jellyfish found by bathers cause painful bites and with a burning sensation, the toxicity of the jellyfish sting varies by species, it could be much more irritating for people with allergic reactions, sensitive skin or very susceptible to bites.
