A new species of purple-colored freshwater crab has been discovered in the Philippines.
“It is known that the crab can make a color distinction. Likely staining is closely linked with the signal function in social behavior,” said Hendrik Freitag of the Senckenberg Museum of Zoology, Germany.
“This explains why large males in many Insulamon species have redder colors than the females and most of the pups are purple,” added Freitag told AFP on Saturday (21/04/2012).
Crabs are found precisely in the Palawan region. Biological wealth of crabs in this region has been studied since 1980, at which time it was discovered species Insulamon unicorn.
Further studies then found the other crab species are also included in the genus Insulamon.
