Scientists have discovered that a chordate animal can regenerate all its organs if it is cut into three pieces.

Scientists say this is a shocking Found that because it is an animal belonging to the phylum Chordata, that is, an animal with a back, which also includes humans. The ability to regenerate organs is not uncommon in the animal kingdom. An example is the ability of a gecko to grow its tail again. However, it is not common for organisms to re-grow the entire body system.

Through Polycarpa mytiligera, scientists have discovered a creature that can regenerate all organs. Even if it is divided into three pieces, each piece clearly knows how to restore the functions of all its missing body systems in a short time. . Project researcher Tal Gordon said that from all angles, this is a simple creature with two openings in its body and a central organ similar to a noodle filter inside the body. The organism absorbs water through the entrance of the body, the filter filters the food particles left in the body, and clean water flows out from the exit.

This study marks the first time that such a high regenerative ability has been found in chordates that only reproduce sexually. In the experiment, the researchers dissected specimens using a method that made parts of the body lack the nerve center, heart, and part of the digestive system. Not only does each part of the organism survive independently in anatomy, all organs regenerate in each of the three parts, thus forming three independent individuals.
