There are many characteristics of Mola. The first is its shape. It looks like a fish head as a whole. The pectoral fin is very small, the dorsal fin and hip fin are developed, but the ventral fin and tail fin disappear. Secondly, it has a huge body shape, with a length of 5.5 meters and a weight of about 3.5 tons. Its skin is very thick and rich in collagen. In addition, it has strong reproductive ability. Adult females can produce 300 million eggs at a time, but the survival rate is very low. 1、 What are the characteristics of Mola 1. Strange shape: the shape of Mola is very unique and looks like a fish head. Its body is flat on its side, and its head is very high, even up to twice its length. The pectoral fin is short, round in shape, without ventral fin, and the caudal fin will gradually degenerate with its growth. Its dorsal and hip fins are well-developed, shaped like a sickle, and will be connected behind the body, looking like a tail fin.
2. Large body and thick skin: the Mola is the largest bony fish with a huge body shape, with a length of 3-5.5 meters and a weight of about 1.4-3.5 tons. And its skin is very thick. The juvenile fish skin can reach about 3.8 cm, and the abdominal skin can reach 7.3 cm after adulthood. In addition, its skin is rich in a lot of collagen, and the content of stratum corneum is more than 44%, which makes many carnivorous fish give up when they bite.
3. Spawning: molas are very fertile. Adult females can release 300 million eggs at a time, the largest of all vertebrates. However, due to its lack of good protection measures, the survival rate of fry is very low, and only 30 fry can grow to adulthood at a time. 2、 Why is Mola called Mola? Mola is a deep-sea fish, but it likes to bask in the sun on the sea, and it lies on the side, like a car overturned, so it has this name. When on the sea, it can control the direction and stroke through its dorsal and hip fins, and can also quickly dive into the seabed. （FanCheYuYouShenMeTeDian，WeiShenMeJiaoFanCheYu）
