A species of shellfish “Thais clavigera” has disappeared in a 30-km coastal area near Japan’s crippled Fukushima nuclear plant, Japanese experts said.

Researchers from Japan’s National Institute for Environmental Studies and National Institute of Radiological Sciences conducted the study in April 2012 on the shellfish’s living status in 43 places from Japan’s Chiba to Iwate prefectures for four months, Xinhua reported.

The team found that the Thais Clavigera was extinct in eight of 10 places within the 20-km-radius alert zone of the nuclear plant.

The plant was damaged by a tsunami in March 2011 and triggered the world’s worst nuclear disaster since Chernobyl in 1986. Other shellfish species such as Cellana grata were found in the alert zone but the amount of them declined.

A high dose of radioactive materials were found inside their bodies, the researchers said. Thais clavigera was found in most places that had been surveyed, they said.
