Organisation appeals for info after 3 blacktip reef shark pups found dead at St John's Island

Marine conservation organisation Marine Stewards is appealing for information after three blacktip reef shark pups were found dead at St John's Island on Monday (July 20).

It shared a photo of the dead sharks taken by Instagram user @emiryusri in a post on its Facebook page on Tuesday (July 21).

The caption on the photo implies someone is believed to have caught the sharks before leaving them for dead.

However, Marine Stewards said the cause of death is still unclear.

The organisation asked for anyone with information to message them directly.

Blacktip reef sharks are known to be found in Singapore's southern waters and typically grow to 1.6m, and up to 2.9m.

They hunt fish in low water and are usually found around submerged reefs at low tide.
