A whale has been washed ashore in Bonny Island, in Rivers State. It was dead and decomposing.
The state of sea creature fuelled suspicions that the waters in the Niger Delta region are massively polluted.
The whale, whose tail and other parts of its body, were already decaying, was discovered by residents of Finima.
It came as oil and gas regulators said they had launched an investigation into the cause of death of thousands of croaker fish, which also washed ashore last week.
The National Oil Spills Detection and Response Agency (NOSDRA) said it has found no oil leaks yet.
It said it was coordinating a multi-agency investigation to uncover the cause of the reported massive death of fishes within the nation’s territorial waters.
