Blackspot Shark (Carcharhinus sealei) at Eastern Johor Straits

Location, date and time: Eastern Johor Straits, off northern shore of Pulau Tekong; 6 July 2012; 0809 hrs.

Observation: Two dead examples of about 60 centimetres total length were found entangled in a gill net. One of them is shown in the attached picture.

Remarks: This small shark, recognized by its black-tipped second dorsal fin, is quite harmless to humans. It is distributed in the Indo-west Pacific, inhabits coastal waters up to 40 metres deep, and grows to a maximum size of 95 centimetres total length (Compagno et al., 2005: 305).
