This most bizarre invertebrate is the fastest among arthropods. They can reach the speed of 10 miles per hour. They are not a species with extremely low metabolism like bird-catching spiders. On the contrary, their metabolism is quite high. In fact, these monsters prey and eat quite frequently, and dare to prey on larger prey. They look like spiders or scorpions between the two sides of the ocean, but they have no poisonous glands, fangs or needles. So in order to make up for the defects, they have very strong jaws. There is no doubt that they are super aggressive. They are one of the killers in the desert at night, and they are typical nocturnal animals, but they still have phototaxis, and lighting is often the cause of their death. (Note: The international imports of shelter from the sun (exporting country: Egypt) are basically wild adult females, and males rarely collect and export them). However, it is sad and regrettable for lovers that they have a short life cycle. Because of this, it is rare to see desert sunscreening spiders raised for more than one year in China.
