The attentive reader will have noticed that Arachnea parapluviosis aquaphosphorescensis appears twice in the Arachnea parapluviosis both under the Parapluvids and the Parasolids. More information on the specific lifestyle of the light-bearing water umbrella spider can be found under the parapluvids entry. This section delves deeper into this dual classification.
As clearly shown in the photos parasolids and parapluvids share a common ecotope. What this means for their mutual relationship remains unclear, but no signs of aggression between the two species have been observed. It is possible they provide evidence that the distinction between these two orders is far less rigid than the categorizing human mind is willing to accept—a typical example of the frogs vs toads debate. Alternatively, this could be a case of convergent evolution, which raises the question which species appeared first and what triggered the specific reproductive strategy unique to this location.
