QUẢNG NINH – Scientists have identified the species of a shark found on the shore of Hạ Long Bay in northern coastal Quảng Ninh Province, whose image was posted on social network recently.
According to report released by the Institute of Marine Environment and Resources on Wednesday, a pigeye shark or Java shark (Carcharhinus amboinensis) is an uncommon species of requiem shark, belonging to the Carcharhinidae family.
Earlier, an image was posted on Facebook of a man holding a fish some 1.5m long, suspected to be a shark that was found on the shore of Hạ Long Bay. This fish was then carried by a man on a motorbike, dan tri news website reported.
However, due to insufficient information on the shark, it is not yet clear whether this species is found in Hạ Long Bay, as suggested in the news posted on social networks in recent days, scientists said.
Another shark species, Carcharhinus amblyrhynchoides, attacked humans at least 10 times off the coast of Bình Định Province’s Quy Nhơn Town a few years ago.
According to research worldwide, the species is found in tropical shallow waters close to the shore, near the surf line and along beaches, and in shallow bays and estuaries. The pigeye shark is large with a thick-set head. Its colour is grey and white.
The pigeye shark is sporadically distributed in the Indo-West Pacific Ocean, scientists said.
It can migrate seasonally to areas where there are reefs to reproduce.
There is no research to prove that it treats humans as prey. – VNS
