Stingrays are a very old fish that existed as early as the Jurassic period 180 million years ago, and they are sharks, but the appearance of stingrays is very strange. Another interesting feature of this stingray is that it can fly, and because it looks good, it is used as an ornamental fish, but it should be noted that stingray is very toxic.
Flying stingrays
In the Jurassic period of the Mesozoic Era, a shark of the same kind appeared, which had the habit of hiding in the sand of the seabed, which is now the fish (hong). Stingrays prefer to potentially sandy bodies, having the function of waiting for fish or shellfish that live on the seabed to approach them to prey on them, or to defend against enemies. Because the stingrays look strange, they are very ornamental.
But there is also a curious thing about stingrays, that is, stingrays can actually fly. What is it like to be a fish in the water that can fly? It turns out that the so-called stingray can fly, not really flying in the air, but in the water. Because stingray pectoral fins are particularly developed, living like a pair of wings, stingrays swim in the water, and the wing-like pectoral fins swim fast in a wavy swing. From a distance, it looks like a stingray flying in the water.
Stingrays are highly toxic
Speaking of which, the history of stingrays can be traced back to ancient times, as early as 140 million years ago, and it is a veteran fish of the elder level. The sea is a cruel fighting ground for the weak and the strong, it is not easy to survive, and its contemporaries are also cartilaginous fish species, the vast majority of which have become extinct, leaving only two major categories of stingrays and sharks. Sharks survive because of ferocity. So, what do stingrays rely on?
