Scientific literature and reference sources indicate that tarantula venom is not lethal to humans, and historical fears or deaths attributed to them are considered misconceptions or pop culture exaggerations.
AIM
Tarantulas are one of the largest predatory arthropods in tropical regions. Tarantulas though not lethal to humans, their venomous bite kills small animals and insect upon which they prey. To understand the abiotic and biotic components involved in Neotropical tarantula bites, we conducted a venom-microbiomics study in eight species from Costa Rica.
METHODS AND RESULTS
We determined that the toxin profiles of tarantula venom are highly diverse using shotgun proteomics; the most frequently encountered toxins were ω-Ap2 toxin, neprilysin-1, and several teraphotoxins. Through culture-independent and culture-dependent methods, we determined the microbiota present in the venom and excreta to evaluate the presence of pathogens that could contribute to primary infections in animals, including humans. The presence of opportunistic pathogens with hemolytic activity was observed, with a prominence of Stenotrophomonas in the venoms. Other bacteria found in venoms and excreta with hemolytic activity included members of the genera Serratia, Bacillus, Acinetobacter, Microbacterium, and Morganella.
CONCLUSIONS
Our data shed light on the venom- and gut-microbiome associated with Neotropical tarantulas. This information may be useful for treating bites from these arthropods in both humans and farm animals, while also providing insight into the toxins and biodiversity of this little-explored microenvironment.
be alarmed, it will bite in order to protect itself, but unless startled or provoked, most bites will be without venom. Venom bites will normally occur
A number of spiders can cause spider bites that are medically important. Almost all spiders produce venom but only a few are able to cause significant harm to humans. Two medically important spider genera have a worldwide distribution—Latrodectus and Loxosceles. Others have a limited distribution.
Medical reports have been criticized for poor evidence. In the last century, both white tailed and wo
The tarantulas of the family Theraphosidae are fearsome-looking spiders and a favorite of movies and television. The fangs deliver a weak venom and simultaneously crush the insect. The Sydney funnel-web spider is a relative with a much more potent neurotoxic venom. Trapdoor spiders, many of which resemble tarantulas but are shinier and less hairy, also have large fangs…
Hogna
Spiders of the genus Hogna are large and powerful wolf spiders.[1] They belong to the Family called Lycosidae. They will readily catch and eat crickets and other large insects. They do not try to hurt humans unless they are getting hurt themselves. Usually their colors are dull, mostly they are brown, dark brown, or black. Hogna carolinensis[2] is the largest spider in the United States and can have a body length (head to tail) of up to almost 1.5 inches or 35mm. They scare people, but it is hard to get them even to try to bite. Instead of showing their fangs, they will run away. They can run very fast. They are about 16 times larger than the smallest species of wolf spiders. For instance, the smallest of the wolf spiders of the genus Trabeops are only 4 mm. long. Hogna carolinensis often digs burrows to live in. Other species in this genus include:
- H. antelucana
- H. baltimoriana
- H. coloradensis
- H. frondicola
- H. lenta
In Europe there is a slightly smaller spider called Lycosa tarantula, a kind of wolf spider that people once believed could kill people. It gets its name from the city of Taranto in Italy.
