What is the constellation of sheep's head fish?

A god beast that originated in India.

Capricorn fish was originally a mythical beast with a long nose, sharp teeth and a fish-like tail in Indian mythology. It is said to be the ride of water, sky and hag, and it is also the incarnation of the goddess Hengjia. In the west, the image of Capricorn is generally the body of a sheep's head fish, which was first estimated to be created by Indians according to the image of a big fish in the ocean. At that time, Indians met some big fish (perhaps like sharks or whales) at sea and saw their power. After it was introduced to China and reinterpreted by Buddhism in China, there were many incarnations, such as a fish with a dragon head (also called ichthyosaur, as shown in Figure 2). Now it seems to appear more in constellations. ?

Here are some introductions about Capricorn, copied from others.

"Capricorn" is a Buddhist language, which is translated into Chinese as Capricorn, Moggi and Mogaro. It is a water beast with a long nose, sharp teeth and a fish body. Its source is probably that ancient Indians combined fish (especially whales), elephants, pigs, crocodiles and other animals. Kelly Yi Yin said, "Capricorn, the big fish in the ocean, devours everything. The Capricorn described in Agama is "eyes like the sun and the moon, nose like Mount Tai, mouth like a valley". With the eastward spread of Buddhism, Capricorn patterns were introduced into China. The Fu Tu of Luoshen, first seen by Gu Kaizhi in the Eastern Jin Dynasty, was generally painted in the Tang Dynasty when Buddhism prevailed. Silver pots and other gold and silver utensils unearthed in the Tang Dynasty all have exquisite Capricorn patterns, especially in Guge City.
