Laver comes from the sea.

It is a red algae plant that grows on shallow sea rocks. Porphyra belongs to the phylum Rhodophyta, Protozoa, Rhodophyceae, Rhodophyceae, etc. in systematic taxonomy. It is a type of seaweed that grows in the intertidal zone. Its distribution range covers the cold zone, temperate zone, and subtropical zone. and tropical seas, Porphyra is the most valuable cultivated seaweed in the world and is cultivated on a large scale in China, Japan and South Korea.

Porphyra is an algae plant of the genus Porphyra in the family Rhodophyceae. The original form of the algae is a flat frond with a short stalk. The fronds growing out of the stalk are broadly lanceolate or oval, membranous, thin and translucent, with wavy edges, light pink when young, and later It turns into deep purple; the growth period of seaweed is from November to May of the following year.

Distribution range:

Porphyry originates from the coastal areas of China. It is a type of seaweed that grows in intertidal areas. Its distribution range covers cold zones, temperate zones, subtropical and tropical seas. China is mainly distributed in the intertidal zone from the Yellow and Bohai Sea to the southeast coast, with a few distributed along the coasts of Taiwan and Hainan Island.

Although Porphyra species are distributed in cold zones, temperate zones, subtropical and tropical seas, the species diversity in subtropical to temperate seas is rich. The geographical distribution of seaweed in China also follows this pattern. It is mainly distributed in the intertidal zone from the Yellow Sea and the Bohai Sea to the southeastern coast. In addition, there are also a few seaweed species distributed along the coasts of Taiwan and Hainan Island, and their distribution has regional characteristics.

The Porphyra species naturally distributed in the Yellow and Bohai Sea are mainly Porphyra striata, Porphyra sweetensis and Porphyra half-leaf. On the southeast coast, the main species are Porphyra striata, Porphyra rugosa and Porphyra longifolia. In addition, Porphyra rotunda is widely distributed along the coast of China and grows from south to north. It is a wide-temperature species.
