Sea star species in the genus Xyloplax life under the sea. Has a life cycle if the connection is broken. As a result, adults body unchanged because he was a child (livescience.com)
VIVAnews disk-shaped animal researchers discovered in the Interior of the Pacific Ocean. Interesting is that animals that are presented in the journal systematic biology, his body was never arrived at the stage of life as adults.
Sea star species of the genus Xyloplax life under the sea in a region where small size in profit. He was only diameter between 2 to 5 millimeters. It also has no weapons as that seen in adult sea stars.
"By staying small, enabling them to get into the nooks and crannies for example gap wood where they could take a number of things around him," said Daniel janies, computational biologist from Ohio State University, quoted from LiveScience, may 5th, 2011.
Researchers know that Xyloplax echinoderm, a group of organisms including starfish, sea lilies, trepang, a fragile and pigs.
As with other echinoderm, Xyloplax vacuum around her body that are useful for respiratory devices, movers, both as a tool for the company. He also kept in a special cage until the phase of the youth reach advanced to later released as an individual living encyclopedia.
However, the first found Xyloplax in 2010 in the waters of the Pacific Ocean at a depth of approximately 2200 metres has a life cycle such as broken. As a result, adults have a body that has not changed since he was in the stage of childhood.
For example, the hand of the sea star are generally grown in menyumbu if the radius of the wheel, as they grow from the stage of childhood to adulthood. But his circumference only Xyloplax grow. Unlike sea stars are supposed to grow hands, he is not the case.
"Small sea star Xyloplax is that the body structure and habitat of the weird," said Janies. "So oddly enough, that we do not recognize as the star of the sea until we know the genome and how it grows," he said. (umi)
