Plant Climbing Behavior in the Scorpion Centruroides vittatus
The American Midland Naturalist, 2000Abstract We examined plant climbing by the common striped scorpion Centruroides vittatus to determine which of two hypotheses (the predation avoidance hypothesis or the increased prey availability hypothesis) best explained this behavior. In the field we observed nocturnal scorpion activity for 16 mo during 1992–1993 to quantify climbing behavior and ...

Ultrastructure of the venom gland of the scorpion, Centruroides sculpturatus (Ewing)
Journal of Morphology, 1972AbstractThe venom apparatus of the scorpion, C. sculpturatus (Ewing) was studied with light and electron microscopy. Each of the paired glands is lined by secretory epithelium made up of a single layer of columnar cells. Extensive folding in the epithelial layer creates a primitive acinar gland.

Optical properties of a scorpion (Centruroides limpidus)
Physica Scripta, 2016Scorpions, elusive by nature, tend to appear nocturnally and are usually not appreciated when encountered. The exoskeleton is capable of fluorescing allowing for their detection at night in order to prevent undesirable encounters. The specificity of their fluorescing suggests specialized optical features.

Inhibition of the angiotensin converting enzyme by venom of the scorpion Centruroides sculpturatus
Toxicon, 1980Abstract C. sculpturatus venom can inhibit angiotensin converting enzyme at relatively high concentrations. Our data indicate that: (1) there are at least several inhibitors present in CSV; (2) one or more of them is heat stable; (3) the inhibitory material behaves as a peptide with respect to NaOH and charcoal treatment; and (4) several of these ...

Bulbotrachystola, a substitute name for Centruroides Breuning, 1940 (Coleoptera Cerambycidae)
Zootaxa, 2019The genus name Centruroides was first introduced by George Marx (in Howard, 1889: 211) for two species of scorpions in the family Buthidae: C. exilicauda (Wood, 1863) and C. luctifer n. sp. The latter species, coming from Indefatigable Is. (Galapagos), lacks a description and has been considered as a nomen nudum and synonym of Centruroides exsul (Meise,

Biochemical studies of the venom from the scorpion, Centruroides sculpturatus
Toxicon, 1964Abstract Results of experiments concerned with the chemical properties and purification of the toxic principle of the venom from the scorpion Centruroides sculpturatus Ewing have been discussed. The crude venom gives positive reactions to several tests for proteins, negative reactions to tests for polysaccharides and shows absorption spectra which ...

Studies on Neotropical Fauna and Environment, 1991
Three cases of hybridization obtained in laboratory conditions between Centruroides gracilis and Centruroides margaritatus bring some evidence on the genetic relationship between these two species. The experiments were done with specimens collected in Florida (USA), Mexico and Colombia.

Effects of venom from the scorpion, Centruroides sculpturatus on the rat
Toxicon, 1964Abstract Anesthetized rats treated with intravenous injections of Centruroides sculpturatus venom developed hypotension, bradycardia and respiratory irregularities. These responses contrast with those reported elsewhere for dogs and cats. The anesthetic used, sodium pentobarbital, had no effect on the LD 50 of this venom.
