Blacktip Reef Sharks (Carcharhinus melanopterus) at Semakau Landfill

Location, date and time: Singapore Straits, reef flat around Semakau Landfill; 29 May 2010; between 0520 and 0550 hrs.

Observation: Three freshly dead examples of around 1 metre total length were found during early morning low tide, tangled in gill nets set over a reef flat (Fig. 1-3).

Remarks: In Singapore, the Blacktip Reef Shark has been recorded around Semakau Landfill (Ng, 2012: 29, 146). This species does not exceed 2 metres in total length, and is distributed in shallow waters on and around coral reefs throughout the tropical Indian Ocean and western Pacific. It has even invaded the eastern Mediterranean Sea via the Suez Canal (Compagno et al., 2005: 302).
