There may be alien creature "out there" - Well many believe that there is - but some weird things live on this planet. In the ocean depths of Australia odd living organisms have recently been discovered.
At first glance they look like floating mushrooms. They are not related to fungi though. The creatures are actually flowering plants and vertebrates. Dendrogramma mostly consist of a stomach surrounded by jelly-like skin.
Scientists believe they are the remnants of early life forms which appeared before the life that went on to dominate the Earth. In other words they were a dead end. They are unique, not related in any way to life that eventually became successful across the globe.
There are a lot of new things still continuing their existence at the bottom of the oceans. Many are very specialized living off toxic substances that would kill other organisms. Don't bother to look for life in the stars. Much still awaits discovery beneath our feet.
