Amphixous

Amphixous are known to be the first ever vertebrates in the world. They are usually found in sand near the tropical seas as well. They are also harvested for people to eat in Asia and for animals to eat them as well. They are a big factor in the sense of evolution and how they were formed millions of years ago. They grow to be about five centimeters long and have a clear, fish like body that has can swim. It makes us wonder how they survive in their environment because they are not very well adapted to where they live.
