a strange guài bug

When I went to the lāo fish with my father this morning, I found a strange qíguài bug.

When Dāng, it was swimming in the water, we thought it was a xiā, and it was brought up.

When I got home, she was xiàngxiā, but it was really not xiā. It also has a slender body with six slender tuǐ on it, four on the body, two in front of the tèshū, jìng grows on the head, and a suō looks like xiàng two chùjiǎo. It also has two tails, which are also thin and long, xiàng two gēn needles. When it swims in the water, the two tus in front are straight, and the four tus in the back are xiàng and dēng, and then the body rushes quickly before the xiàng, xiàngsài on the field, the speed of the shhu huátǐng.

Dad said that it is called water pá, but I don't know what its scientific name is. If you know, please tell me please?

What a strange guìi and yìsi bugs!
