Scientists at the Senckenberg Research Institute in Germany and De La Salle University in Manila found the four new species of Insulamon freshwater crab genus as part of their Aqua Palawana research program.
The reddish-purple crabs are the only varieties that are endemic to only one or a few islands; the sea keeps them from spreading further, as they depend on freshwater at all stages of their development. Having been completely separated from their relatives, they have developed their own separate species and genera over tens of thousands of years.
According to National Geographic, The particular violet coloration might just have evolved by chance, and must not necessarily have a very specific function or reason aside from being a general visual signal for recognition.
