The carnivorous Geosesarma hagen enjoys its meals from insects living on the ground in the dense bottom vegetation. The adults are about 13 millimeters wide. They have bright orange claws and vivid colors that can extend through out their backs too. Although some of their backs will remain brown. They were named after the Rolf C. Hagen Group of Companies, which is a major pet supplies company in Germany that supported the research of these crabs.
Unlike the hagen, the dennerle live under and between rocks among vegetation on the slopes of a small valley, eating grasshoppers, larvae, and plant detritus.
The adults are usually a little bit larger at 14 millimeters wide. These received their name after the German company Dennerle, which also supported their work.
In Indonesia, the selling and trade of these specific crabs has been going on for over a decade. But researchers have never actually named this new crab species before. One researcher states “They start collecting in areas where scientists may not have made any expeditions so far, and suddenly the market is formed with some animals that no one has ever given a name.” Are you a crab fan? Would you want one of these unique crabs as a pet?
