Although the scientific community does not fully agree, it is believed that there are between 20 and 25 different species of sturgeon.
They have a wide mouth located at the bottom of the head and have four barbels that look similar to mustaches that they use to locate food. When they find a snail or small fish, they suck it. They have five rows of longitudinal bone plates. And unlike other fish, the sturgeon does not have bones but bones.
