Sensory hairs cover the pincers and tail, enabling the emperor scorpion to detect prey through vibrations in the air and ground. [5] When gravid (pregnant), the body of a female expands to expose the whitish membranes connecting the segments. The emperor scorpion fluoresces greenish-blue under ultra-violet light. [6] [7]
Members of Pandinus are generally large scorpions (about 120–200 mm total length), which are dark to black colored, sometimes with paler metasoma and legs. The pedipalp pincers are massive, while the metasoma is proportionally thin with a small vesicle and stinger (aculeus).
Scorpion venom serves to kill or paralyze prey rapidly. The stings of many species are uncomfortable, but only 25 species have venom that is deadly to humans. Those species belong to the family Buthidae, including Leiurus quinquestriatus , Hottentotta spp., Centruroides spp., and Androctonus spp. [ 39 ] People with allergies are especially at ...
The deathstalker is one of the most dangerous species of scorpions. [10] [11] Its venom is a powerful mixture of neurotoxins, with a low lethal dose. [12]While a sting from this scorpion is extraordinarily painful, it normally would not kill a healthy adult human.
Scorpion venom is a mixture of several types of neurotoxins which, consequently, makes the venom more effective upon a wider range of prey species and helps the scorpions overpower and capture prey.
Pandinotoxins are the most potent inhibitors of the rapidly inactivating A-type voltage-gated potassium channels. [3] They also block the delayed rectifier, slowly inactivating channels of the subfamily A member 2 (Kv1.2/KCNA2) [1] and they can reversibly block the shaker B potassium-channels (Kv1.1 sub-family).
Paruroctonus boreus, commonly known as the northern scorpion, [1] [2] [3] is a species of scorpion in the family Vaejovidae. It is the northernmost species of scorpion, the only scorpion found in Canada , [ 3 ] and one of the scorpions with the broadest distribution over North America .
