An important criterion for identifying the grade of abalone is the number of heads. The so-called head refers to the number of abalones of uniform size in one pound (about 0.6 kg), such as 2, 3, 5, 10, 20, etc. The fewer the number of heads, the larger the abalone. The price becomes more expensive, so it is said that it is difficult to buy two abalone if you have money. One and two abalones are of the highest quality and are rarely seen. Among the many abalones, Japanese net abalone has the smallest number of heads, followed by Jipin. Hema has the smallest size and the largest number of heads.
