A mushroom-shaped sea animal discovered off the Australian coast has defied classification in the tree of life.

A team of scientists at the University of Copenhagen says the tiny organism does not fit into any of the known subdivisions of the animal kingdom.

Such a situation has occurred only a handful of times in the last 100 years.

The organisms, which were originally collected in 1986, are described in the academic journal Plos One. ...

Pretty interesting. It'd be very exciting if it does end up being a "living fossil" from the Ediacaran period, which the article hints at. We'd have another coleacanth (http://en.wikipedia.org/wiki/Coelacanth)situation all over again, which certainly isn't bad news for the world of biology!

Too bad they didn't put any DNA aside -- but morphologically, it looks like a branch-off from the common ancestor of anemones/corals and jellyfish.

It also resembles a tunicate, there may be some connection with this.

I take this back. I forgot tunicates were closely related to chordates, if anything the visual resemblance says nothing and we will only know more from DNA.

Doesn't happen too often.
