A popular species of crab particularly kept as pets, the vampire crab have finally had their species origin figured out.
Researchers have traced the vampire crab’s genome back to Southeast Asia where these crab exist in freshwater rivers. The newly described species of crab eosesarma dennerle and Geosesarma hagn have been discovered and found in separate river valleys on the Indonesian island of Java.
“These crabs are kind of special because they’ve been around in the pet trade for ten years, but no one knew where they come from,” notes study co-author and professional aquarist Christian Lukhaup of Waiblingen, Germany.
The vampire crabs are distinctly marked with glowing yellow eyes, and a purple-ish tinted body that boasts large purple claws.
