The team, led by professor Ho Ping-ho, was conducting research at Taiwan's Kenting National Park in June to determine the environmental impact of an oil spill there when they happened upon two of the unusual crabs. The crabs, both female, were tiny -- the larger is only an inch long -- and, at the time of the discovery, one was already dead and the other was dying. The two deceased crabs have since been made into specimens, and Ho plans to study them further and write about them.
