Water bear worm is a small aquatic animal, also known as slow-moving animals  Water bear worm is the most resilient creature known on Earth, it can survive without protective measures in extreme pressure environment  The strange ability of slow-moving animals prompted researchers to investigate their genes  The results of the first genome test on slow-stepping animals show that horizontal gene transfer is carried out during the evolution of slow-walking animals
Water bear worms inherited all the genetic material from their ancestors and found no plants or microorganisms
 A large number of genes are obtained from other species
