Radar scorpion is the same as Spider, belonging to Arachnida, but different from Scorpion, it belongs to Whiptail Scorpion (or is classified as Whiplash), so it is not True scorpions can also be found in Japan. The arrangement of the basal ganglia of the thoracic appendages is similar to that of spiders, and the linear whiptail resembles the scorpion stinger, but it is not poisonous and slightly clothed with tentacles. It is a small whip scorpion species.

Radar scorpions

Whiptail scorpions range from small to large . The American giant whip anal scorpion has a body length of 65 mm. The body is divided into two parts, anterior and posterior. The front body is covered with carapace, and there are 8-12 eyes on the carapace, divided into 3 groups, there is 1 group in the middle of the near front end, which are 2 middle eyes; 1 group on each side, each consisting of 3-4 eyes . The chelae are divided into 2 segments, the second segment is the chelic teeth, which together with the protrusion of the basal segment form forceps. The tentacles are stout and divided into 6 segments: basal segment, trochanter, leg segment, tibia, basal tarsus and tarsus. There is a sheet-like protrusion on the inner edge of the trochanter with many serrations. The inner end of the tibia also has a distinct protrusion, the end of which is cone-shaped in females and rod-shaped in males. There is a protrusion (or immobile finger) and the tarsus (or movable finger) on the inner edge of the end of the basal tarsus to form a forceps. Step foot is generally divided into 7 sections. The 1st leg has no knee, and the tarsus is divided into 9 small rings. The 1st foot senses chemical stimulation and humidity and is not used for walking. The 2nd to 4th pairs of feet are walking feet, with knee joints; the tarsus is divided into 3 sections, with 3 claws at the end, and the movement is generally slow.

The posterior body (abdomen) originally consisted of 12 segments. Section 1 forms a ventral peduncle; Sections 2 to 9 are wide and distinct, with dorsal plates, webs and lateral membranes; Sections 10 to 12 are degenerated and very small, and the dorsal plates and webs of each section are healed; the 12th abdomen After the section is the tail whip, which consists of about 30 to 40 subsections. The genital pore is at the posterior edge of the web of the second segment of the posterior body. There are two pairs of book lung holes, located on the posterior edge of the web of the 2nd and 3rd abdominal segments. The anus opens at the 12th abdominal segment. There is a pair of anal glands in the back half of the hind body, opening on both sides of the anus. When a whip scorpion is frightened, it lifts the back of its abdomen and shoots out the secretions of the anal glands. The secretion of the whip anal scorpion contains 84% acetic acid and 5% caprylic acid, and the caprylic acid makes the acetic acid penetrate into the body of the arthropod. The secretions of the anal glands can burn a person's skin. The excretory organs are the basal ganglia glands and Malpighian ducts.
