While we always love reading about the discovery of new critters (rather than their impending doom), these ones brought us particular joy to look at due to their bright purple and orange coloring. The four new species of crabs, discovered on Palawan Island in the Philippines, are freshwater creatures living in rivers and streams.
The man who discovered the new species, Hendrik Freitag, told Phys.org about their coloring, “It is known that crabs can discriminate colours. Therefore, it seems likely that the colouration has a signal function for the social behaviour, e.g. mating.”
He continued, “This could explain why large males of various Insulamon species are more reddish compared to the generally violet females and immature males.”
The species were named, starting with the largest, Insulamon magnum, Insulamon palawense, Insulamon johannchristiani and the smallest, Insulamon porculum. When we say large, we’re talking just over two inches in width. You can learn more about their physiology on the journal Raffles Bulletin of Zoology.
Freitag noted that there are threats to the species mostly from habitat destruction. He said, “Even if the habitats are not entirely destroyed, the smaller the remaining habitats, the higher the risk of extinction for a species.”
