Ascidiacea - Ascidiacea

Berries are animals that look like plants, distributed throughout the oceans: From the tidal inundation (brackish water) to the deep sea, thousands of meters are visible. The berries are clinging to the dense crust, affecting the speed of running the train, consuming fuel, it clings to the underground pipe to block the pipe. But the tail of young pepper

there is a spine, a sign of high-level animals, people are listed in the vertebrate. Customs have an important effect in studying vertebrate origins in evolution.

The shape of a pepper is like a tomato, sometimes like a flower, which looks very much like a tea kettle. If you poke it with your finger, it will spew a very strong water flow, then slowly stand upright, it is softly drooping like cotton.

The pepper is an animal that lives in place, the outer shell encapsulates a Cellulose shell that protects and mold shapes. This is the only phenomenon of the animal world. So called a pepper (pepper is a shell). Thanks to the water inlet and outlet pipes to absorb oxygen, through the intestine to absorb nutrients and small organisms in the water.

There are sea lilies when spawning from the body growing out of a preschool , this germ grows up and leaves the mother's body to develop into a new body. That is the real germ of the pepper. There are marine species that reproduce sexually , then, bisexual pepper, eggs and sperm are not mature and cannot be self-consumed, must "go back" to other customs.

Young sea lilies are very similar to tadpoles, eyes, brain and tail are very developed, there is a spine in the middle. The back of the spinal cord has a neural tube that goes straight to the end of the body, the gills of the gills and the young pepper can freely swim. After a few hours, the tip of the new body gradually protrudes into other objects. Then the tail wilted, then completely lost, eventually keeping only one neuron.The metamorphosis from small to big of the sea is contrary to the evolutionary way so zoology is called reverse metamorphosis.
