Neotropical Land Planarian (Pseudogeoplana), Caquetá, Colombia

The highlight of this night tour was our first ever observation of a flatworm (planarian). This one is a Neotropical Land Planarian (Subfamily Geoplaninae), probably genus Pseudogeoplana. This genus is a temporary dumping ground of species that need to be redescribed.

Planarians have a remarkable biology. One of which is that they are theoretically immortal, they can regenerate any missing body part, including their head.

  Welcome!
  
  To be slightly annoying, saw that you added it to this list:
  
  Slugs and snails and worms!
  
  Note that planarians are not really worms, but it's just a technicality :)
