Common name: Sea ear.
Origin and production period:
Mainly produced in Taiwan, Hainan and other places in China, among which Sanya City, Xisha Islands and other places produce more.
The shells are long and narrow, with about 3 layers of spirals. The spirals are small, and the body spirals are large. They adapt to the mouth of the shell and the whole shell is twisted into ears. A spiral rib on the left side of the shell surface consists of a row of approximately 20 or so neatly arranged protrusions, of which 5 to 7 protrusions have openings. The left side of the rib to the edge of the shell has 4 to 5 ribs. Birth and detail. The surface of the shell is smooth, green, yellow-brown, and covered with purple, brown, dark green and other stripes. The shell is silvery white with pearl luster. The foot is extremely developed and cannot be completely enclosed in the shell.
In biology, folliculogenesis is the maturation of the ovarian follicle, a densely packed shell of somatic cells that contains an immature oocyte. Folliculogenesis describes the progression of a number of small primordial follicles into large preovulatory follicles that occurs in part during the menstrual cycle.
Estrogen levels peak towards the end of the follicular phase. This causes a surge in levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). This lasts from 24 to 36 hours, and results in the rupture of the ovarian follicles, causing the oocyte to be released from the ovary.
