The Venezuelan scorpionfauna comprises 17 genera and species. In some taxa the taxonomy is unclear, and additional studies that contribute to the knowledge about taxonomic identity and relationships are necessary. Geometric morphometrics is a tool that has been used as support to the systematics in different organisms. The goal was to analize the isometric size and conformation in five scorpions species.
We photographed individuals of four speceis of Buthidae: Centruroides testaceus, Rhopalurus laticauda, Tityus. Bothriurus pichicuy, a new scorpion species from the center coast of Chile, is described. It belongs to the vittatus species-group, and differs from the others species in the group by the pigmentation patterns of the prosoma, mesosoma and venter of metasoma, by the development and arrangement of the ventral keels of caudal segment V, and for its small size.
The species is the only representative of the vittatus species-group that lives in sympatry with another Bothriurus species: B. Full Text Available Bothriurus pichicuy, a new scorpion species from the center coast of Chile, is described.

A list of species of scorpions recorded for the state of Guerrero is included after the revision and correction of historical records. Se recolecto un total de 6 ejemplares 15 familias y 50 especies. Scorpion fish sting. Scorpion fish are members of the family Scorpaenidae, which includes Insects and Scorpions. Stinging or biting insects include bees, wasps, hornets, and fire ants.
The health effects of stinging or biting insects or scorpions range Full Text Available Using pitfall traps, the species composition and abundance of solpugids were studied in several ecotopes of Chile's transitional coastal desert. Five species were recorded: Procleobis sp. The similarity dendrogram obtained from the Bray-Curtis matrix indicates that there are 3 groups of ecotopes: steppe, dune, and a miscellaneous group. From the data it is inferred that the diversity and abundance of solpugids in the ecotopes studied may be related to plant structure and to the pedological conditions of the habitat.
Unlike the amphibians, birds, mammals and reptiles, scorpions have no back bone, as they are invertebrates. Scorpions belong to the phylum arthropoda, their bodies are segmented and their legs are jointed. They belong to the class arachnida , because they have eight legs, two pedipalps, two chelicerae and a body composed of eighteen segments. The most important species of Buthidae family are Buthotus tamulus, Leiurus quinquestriatus, Androctonus crassicauda, Androctonus australis, Tityus serrulatus, and Centruroides suffusus Minton, Classification of scorpions from Africa and Middle East, has been summarized by Vachon, Unlike snakes, all scorpions are venomous.
The venom is injected by means of a stinger found at the tip of the telson, the terminal structure of the tail. The smallest adults may range from approximately 2 to 3 cm and the largest between 15 to 25 cm Bucherl, Scorpions have quite variable life spans.
The age range appears to be approximately 4—25 years. The death stalker Leiurus quinquestriatus , is a member of the Buthidae family. It is also known as Palestine yellow scorpion , Omdurman scorpion , Israeli desert scorpion and numerous other colloquial names. To eliminate confusion, especially with potentially dangerous species, the scientific name is normally used to refer to them. The name Leiurus quinquestriatus roughly translates into English as f ive-striped smooth-tail.
Other species of the genus Leiurus are often referred to as d eathstalkers a s well Werness, ; Minton, Scorpion image segmentation system. Death as a result of scorpion sting has been a major public health problem in developing countries. Despite the high rate of death as a result of scorpion sting, little report exists in literature of intelligent device and system for automatic detection of scorpion. This paper proposed a digital image processing approach based on the floresencing characteristics of Scorpion under Ultra-violet UV light for automatic detection and identification of scorpion.
The acquired UV-based images undergo pre-processing to equalize uneven illumination and colour space channel separation. The extracted channels are then segmented into two non-overlapping classes. It has been observed that simple thresholding of the green channel of the acquired RGB UV-based image is sufficient for segmenting Scorpion from other background components in the acquired image.
Two approaches to image segmentation have also been proposed in this work, namely, the simple average segmentation technique and K-means image segmentation. The proposed algorithm has been tested on over 40 UV scorpion images obtained from different part of the world and results obtained show an average accuracy of The proposed 1system will eliminate the problem associated with some of the existing manual approaches presently in use for scorpion detection.

Clinical update on scorpion envenoming. Full Text Available Abstract: Scorpion stings are currently the leading cause of venom-related injury to humans in Brazil and are a significant public health problem globally. Only scorpions of the Tityus genus are of medical importance in Brazil, and Tityus serrulatus is responsible for the most serious envenomations and deaths. The toxic effects of scorpion envenomation are due to a massive release of sympathetic and parasympathetic neurotransmitters; the severity is related to cardiac and hemodynamic changes, with cardiogenic shock and pulmonary edema contributing to the main causes of death.
Currently, the clinical data point to catecholamine excess as the cause for reversible scorpion cardiomyopathy. These data include electrocardiographic changes, profiling of cardiac enzymes and troponin I, echocardiographic data with global or regional left ventricle dysfunction, and myocardial perfusion alterations compatible with spasm in the coronary microcirculation. Furthermore, recent data on cardiac magnetic resonance imaging findings, which are similar to those observed for stress-induced cardiomyopathy, have also been linked to catecholamine excess.
The efficiency of antivenom serum treatment is controversial in the literature. Our experience in Brazil is that the management of patients with systemic manifestations of scorpion stings is based on three approaches, all of which are extremely important.
These include symptomatic treatment, antivenom serum, and cardiorespiratory support. Biochemical, transcriptomic and proteomic analyses of digestion in the scorpion Tityus serrulatus: insights into function and evolution of digestion in an ancient arthropod.
Scorpions are among the oldest terrestrial arthropods and they have passed through small morphological changes during their evolutionary history on land. They are efficient predators capable of capturing and consuming large preys and due to envenomation these animals can become a human health challenge.
Understanding the physiology of scorpions can not only lead to evolutionary insights but also is a crucial step in the development of control strategies. However, the digestive process in scorpions has been scarcely studied.
In this work, we describe the combinatory use of next generation sequencing, proteomic analysis and biochemical assays in order to investigate the digestive process in the yellow scorpion Tityus serrulatus, mainly focusing in the initial protein digestion. The transcriptome generated database allowed the quantitative identification by mass spectrometry of different enzymes and proteins involved in digestion.
All the results suggested that cysteine cathepsins play an important role in protein digestion. Two digestive cysteine cathepsins were isolated and characterized presenting acidic characteristics pH optima and stability , zymogen conversion to the mature form after acidic activation and a cross-class inhibition by pepstatin.
