Scorpions and their Venom [PDF]

open access: yesNature, 1922
PHYSALIA in “Animaux Venimeux,” p. 252, says that in all venomous animals their immunity to their own venom is limited, and announces that in an experiment a scorpion, Bulteus australis, was killed by an injection of the same venom as its own. I should like to add further observations from personal experience, bearing on this very interesting subject.

The Dual α-Amidation System in Scorpion Venom Glands [PDF]

open access: yes, 2019
Many peptides in scorpion venoms are amidated at their C-termini. This post-translational modification is paramount for the correct biological function of ion channel toxins and antimicrobial peptides, among others.

Microbiota discovered in scorpion venom. [PDF]

open access: yesPLoS One
Abstract With low nutrient availability and presence of numerous antimicrobial peptides, animal venoms have been traditionally considered to be harsh sterile environments that lack bacteria. Contrary to this assumption, recent studies of animal venom and venom-producing tissues have revealed the presence of diverse ...

The myth of scorpion suicide: are scorpions insensitive to their own venom? [PDF]

open access: yesJournal of Experimental Biology, 1998
ABSTRACT The resistance of the scorpion Androctonus australis to its own venom, as well as to the venom of other species, was investigated. A comparison of the electrical and pharmacological properties of muscle and nerve fibres from Androctonus australis with those from the crayfish Procambarus clarkii enabled us to understand the lack ...

Anticoagulant Activity of Low-Molecular Weight Compounds from Heterometrus laoticus Scorpion Venom

open access: yesToxins, 2017
Scorpion venoms are complex polypeptide mixtures, the ion channel blockers and antimicrobial peptides being the best studied components. The coagulopathic properties of scorpion venoms are poorly studied and the data about substances exhibiting these ...

A first molecular characterization of the scorpion telson microbiota of Hadrurus arizonensis and Smeringurus mesaensis.

open access: yesPLoS ONE, 2023
Scorpions represent an ancient lineage of arachnids that have radiated across the globe and are incredibly resilient-since some thrive in harsh environments and can exist on minimal and intermittent feedings.

Exploring the biological activities and proteome of Brazilian scorpion Rhopalurus agamemnon venom [PDF]

open access: yes, 2021
Scorpion venoms are formed by toxins harmful to various organisms, including humans. Several techniques have been developed to understand the role of proteins in animal venoms, including proteomics approach.

From biology to biotechnology: Host‐regulation factors from parasitoid wasps are a source of bioactive molecules with translational potential

open access: yesInsect Molecular Biology, EarlyView.
Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

A neuro‐behavioural model of neophobia

open access: yesBiological Reviews, Volume 101, Issue 4, Page 1863-1876, August 2026.
ABSTRACT Fear can be defined as the internal neurological state that releases a repertoire of behaviours an animal performs to reduce the effect of an aversive factor. Neophobia, the fear of novelty, is a fundamental behavioural trait observed across a wide range of species from arthropods to humans.

She Doesn't Whisper: Female‐Prominent Stridulation Shaped by Morphology in a Buthid Scorpion and Insights on Its Function

open access: yesEthology, Volume 132, Issue 8, Page 533-543, August 2026.
Sexual dimorphism and stress‐induced stridulatory responses in Jaguajir rochae (Borelli, 1910). Females exhibited greater absolute pectinal size and higher sound pressure levels, whereas males showed higher pectinal allometric ratios relative to body size, lower sound frequencies, and shorter delta times.
