Insulamon palawanense
Insulamon palawanense, or the Palawan purple crab is a species of freshwater crab from the Philippines described in 2012. They are wide and are a striking purple colour.History
The species was described by Hendrik Freitag of the Senckenberg Museum of Zoology in Dresden, Germany, having previously been included in a wider circumscription of I. unicorn. The species is endemic to the island of Palawan, where it has a wide distribution. The striking iridescent purple coloration may help the crabs to recognise others of its species, or may serve no purpose.
