Starfish belong to the echinoderms of the phylum in the subphylum. Their ancestors lived in the early Ordovician period, 450 million years ago, and were originally filter-feeding marine organisms. After hundreds of millions of years of long evolution, they have finally evolved into what they are now. Maybe you may think there is nothing wrong with it! Let's take an example of the evolutionary pace of the starfish family's cyberpunk style.
A great variety of starfish
Looking at the appearance first, you may think that the five-pointed star looks beautiful on the outside. But we need to know that most creatures on earth are symmetrical, such as these beautiful boys in the picture below. The starfish evolved into the shape of a five-pointed star. It's unbelievable to think of this design!
The vast majority of living things on Earth are symmetrical structures
Let's talk about the simplest behavior of animals - eating. Generally animals have evolved mouthparts specifically for devouring food, and eating is to swallow food in the mouth and swallow it into the stomach. And starfish are playing flowers in this most basic place. Most starfish first spit out their stomachs to wrap up the food when they eat, and digest almost as much as they pack and stuff their stomachs together into their bodies. This eats like we have to serve.

Talking about wisdom again, starfish does not have brains, not that starfish did not evolve brains, starfish ancestors once had brains, but long-term living in the relatively calm seabed without brains to throw away
In addition, starfish has also played a new trick in reproduction, the following picture is the larvae of starfish, is it not at all like an adult starfish? Yes, it is not an adult starfish, the real adult starfish is the small yellow flower that grows on the body of the larva, and the larva grows a small flower after the adult, and then the small flower falls off to become a starfish, and the larva shrinks and sinks to the bottom of the sea to die. In layman's terms, it is not that you grew up when you were a child and became the current you, but that you grew up from the you when you were a child.
