Scorpions are members of the class Arachnida and are closely related to spiders, mites, and ticks. They are commonly thought of as desert dwellers, but they also live in Brazilian forests, British Columbia, North Carolina, and even the Himalayas.
Scorpions first appeared as aquatic organisms during the Silurian period, about 450 million years ago. They were among the first animals to adapt to land living, about 420 million years ago. Scientists think that scorpions may have originated on land, been swept into the ocean, evolved, and then reemerged.
The first trees appeared during the Devonian period, between 350 and 420 million years ago.
Eurypterids, often informally called sea scorpions, are a group of extinct arthropods that form the order Eurypterida. Eurypterid just looked like the scorpion accept for the size which was basically 2.5 Meters long.
They didn't change their appererance or made natural selection to happen because the scorpions have a dna copy, where if one of the dna will be on the nucleus, if it is mutated, then we will use the second one. Like that , it never changed that much.
The venom contain neurotoxic peptides which are responsible for the symptoms that present during envenomation by interacting with ion channels and have the potential to cause massive damage to nervous system of both vertebrates and invertebrates.
But everything have a advantage.
It's really hard to notice the tumors. In addition to chlorotoxin, several other ion channel blockers have been isolated from scorpion venom, including iberiotoxin, margatoxin, and charybdotoxin, all of which could serve as potential therapeutic agents due to their antiproliferative effects on cancer cells.
The Chlorotoxin will be attatched to the cancer cells without affecting any other cells or body part. If we illuminate it, The scientists thought that it can show us were is the tumor.
Grasshopper mice are resistant to scorpion venom because of a mutation in their pain response pathway. The venom from a bark scorpion attaches to a protein called Nav1.
When the grasshopper mouse is stung, the scorpion toxin binds to one of the mouse's sodium channels, closing it and preventing the mouse from feeling pain.
Scorpions glow in UV light. However, scientists have observed that scorpions don't glow after molting. This suggests that the Scorpions have a hyaline layer in their exoskeleton that reflects certain wavelengths of ultraviolet (UV) light. Bye.
