Because of this, they are also often referred to as the ciliary worms.
Planaria is a typical hermaphroditic, so after internal fertilization without the participation of other individuals on light appears fully viable offspring. The planaria eggs are resistant to high and low temperatures, so get rid of them is quite difficult. These worms there is no one specific organ of respiration, the aeration process occurs with just the skin. Continue reading
