Fluorophores from the hemolymph of yellow sac spiders (Cheiracanthium mildei) have been characterized using excitation emission matrix (EEM) fluorescence spectroscopy. This approach provides characterization of fluorophores present in the organism without having to isolate pure samples. Minimal variation occurs between individual samples and each EEM has two distinct peaks, suggesting two fluor...
Received 4 January 2005. Accepted 9 November 2005. Distributed December 2005. Abstract Circumstantial evidences for mimicry of scorpions by the neotropical gecko Coleodactylus brachystoma (Squamata, Gekkonidae) in the Cerrados of central Brazil. There are few records of invertebrates mimicry by reptiles. In the Cerrados of central Brazil, the small Coleodactylus brachystoma is an endemic specie...
Representing a basal branch of arachnids, scorpions are known as 'living fossils' that maintain an ancient anatomy and are adapted to have survived extreme climate changes. Here we report the genome sequence of Mesobuthus martensii, containing 32,016 protein-coding genes, the most among sequenced arthropods. Although M. martensii appears to evolve conservatively, it has a greater gene family tu...
In the dry zone between North Africa and South Asia scorpions have caught the imagination of nomads and sedentary people in various ways. First of all, venomous scorpions have long been considered as embodiments of evil, but also as protectors to counter the powers of other evil forces. This is reμected in beliefs, in pictorial representations of oriental art from early historic periods, and in...
This brief review summarizes the studies in systematics and zoogeography of European scorpions. The current “splitting” trend in scorpion taxonomy is only a reasonable response to the former “lumping.” Our better understanding of scorpion systematics became possible due to the availability of new morphological characters and molecular techniques, as well as of new material. Many taxa and local ...
Abstract. Shahi M, Jaberhashemi SA, Hanafi-Bojd AA, Akbari Rafinejad J. 2021. Faunistic study on scorpions and their health impact in Bashagard County, Hormozgan Province, Southern Iran. Nusantara Bioscience 13: 85-90. Scorpion sting is a major public problem tropical subtropical countries, endangering thousands of lives annually. About 2300 scorpion cases including several deaths are reported ...
The fauna and zoogeography of the scorpions in the Aegean area are not well researched and based upon specimens randomly collected and described by various authors in the past 150 years. A first revision ot the scorpions in this region was provided by Kinzelbach in 1975 (completed with maps in 1985). However, the taxonomical validity of some species and most of the subspecies, first of all thos...
Scorpions possess two types of visual organs, the median and lateral eyes. Both eyes consist of simple ocelli with biconvex lenses that differ in structure and function. There is little variation in the number of median ocelli across the order. Except for a few troglomorphic species in which the median ocelli are absent, all scorpions possess a single pair. In contrast, the number of pairs of l...
