A fisherman from Qingdao recently found nine rare species of sea cucumbers in wreck of a sunken fishing boat, according to the qingdaonews.com.

Zhang said he dived into the sea to figure out what his boat anchor was stuck on and discovered the sea cucumbers and an abalone in sunken wreckage. The cucumbers are unusually big, with each weighing about 1.4 kilograms.

Zhang sold the abalone for 200 yuan (US$25) but kept the cucumbers, as they are a rare species with high nutrition value.
