Terrestrial flatworms (Australoplana sanguinea) When I upturned a rock in the garden there was a flattened pile of pale orange jelly. As it was suddenly exposed to the sun it came alive and turned out to be two geoplanarians. They quickly stretched out looking for darkness and moisture so I poured a little water onto the rock. They found their way down the wet trail into shade in about 30 seconds. Both were about 80mm long fully extended. The pointy end is the head... eyes at the other end !!<br />

  1. Thank you for describing the undescribed! A strange life form to say the least.

    PS: you seem to know the species, shall I create the record for it?

    1. Oops.. sorry I didn't see this one Ferdy.
      If Leigh Windsor won't go to species level on it then I wouldn't argue with him.
      Whether we put that name in the database is up to you. After the chat with Leigh I wish I had tried to snap the back end where all the eyes are. I think it's weird to only see where you've been in life and not where you're going. ;-)

    1. Thanks Jivco.
      Believe it or not I felt sorry for these things.. it was about 41C that day and no rain for weeks.
