A SCHOOL of baby hammerhead sharks, similar to those washed ashore about two weeks ago, has been spotted in waters around Nukulau Island.
And Department of Fisheries senior fisheries officer Sunia Waqainabete says the process is normal.
He said since the upper Rewa River was a nursery for sharks, these baby hammerhead sharks would swim offshore and stay there for five to six weeks before finding their way to the ocean.
Samisoni Tuibale, who is in charge of taking people across to the island, said a school of baby hammerheads was discovered between mangroves around Nukulau.
"I travel to the island everyday and this is the first time I came across this," he said.
"But one can tell these sharks have been there for quite some time."
The Department of Fisheries said the most probable cause of the mass death of the juvenile sharks two weeks ago was that they got entangled in fishing nets.
Mr Waqainabete said according to their investigations, it was possible that the sharks were trapped in a fishing net.
He said another possibility was that baby sharks were attacked by dolphins. However, he said this could not be confirmed because the nature of their injuries was the same on either the right or left side of the head.
