It wasn't exactly the 8m-long great white shark portrayed in the iconic film Jaws, but a 1.5m-long blacktip reef shark spotted near Sentosa's Palawan Beach on September 1 generated a flurry of emotions.
Sentosa briefly halted swimming and water activities at the beach, which resumed only at 9 a.m. the following day after drone checks confirmed that no further sharks had been observed.
In a video of the incident on September 1 that leaked online, beachgoers appear both enthralled and wary. Men, women, and children are seen keeping their distance from the beast, however many are equipped with cell phones, hoping to get a photo or video of it as it glides over the water.
The sighting of the blacktip reef shark near Sentosa's Palawan Beach serves as a reminder of the delicate balance between human recreation and marine wildlife. While such encounters are rare, they highlight the importance of coexistence and respect for the natural habitats that surround our urban areas. Experts emphasize that these incidents should not be cause for panic, but rather an opportunity to educate the public about marine life and conservation efforts.
Online, users voiced fear and curiosity about sharks in Singapore's seas. Some were concerned about swimmers' safety, while others were intrigued by the unusual meeting.
Here's all you should know about sharks in Singapore seas.
Home to more than simply the Blacktip reef.
According to the National Parks Board's list of marine fishes, Singapore seas are home to 13 shark species, according to Dr Zeehan Jaafar, a senior lecturer at the National University of Singapore and marine life expert.
Aside from the blacktip reef, other species include the coral catshark, which may grow up to 70cm long, and the whale shark, which can reach lengths of 5m to 10m, with the longest on record measuring 18.8m and spotted in the northwestern Indian Ocean.
The diversity of shark species in Singapore's waters is a testament to the rich marine ecosystem that exists alongside the city-state's bustling urban landscape. This biodiversity not only contributes to the overall health of the ocean but also provides unique opportunities for scientific research and eco-tourism. However, the presence of these various shark species also underscores the need for responsible coastal development and marine conservation policies to ensure their continued survival.
Most are endangered.
According to the Singapore Red Data Book, which includes scientific and popular names as well as details of each plant and animal species, seven shark species are critically endangered, five are endangered, and one is data-deficient.
Dr Zeehan stated that the tiger shark is the species with the least amount of data because there has only been one documented sighting of it in 1967, and it has not been observed in Singapore waters since then. She stated that there are currently no species-specific conservation activities for native sharks.
'Timid' beachgoers.
The blacktip reef shark lives in shallow reef areas and forages near the shore, according to Dr Zeehan. The species is locally endangered, usually timid, and not noted for being aggressive. It feeds on tiny fish and invertebrates.
Dr Zeehan further stated that the blacktip reef shark is native to Singapore and has always been present in its waters. When compared to other shark species, they are the most commonly encountered.
It is usual for some sharks to swim near the beach. Assistant Professor Benjamin Wainwright of Yale-NUS College explained that they do this for a variety of reasons, including foraging for meals, fleeing larger predators, and giving birth in shallower, calmer waters.
The recent sighting of the blacktip reef shark at Sentosa's Palawan Beach has sparked renewed interest in marine conservation efforts. Local environmental groups are seizing this opportunity to raise awareness about the importance of protecting these endangered species and their habitats. Some organizations are now calling for increased funding for research and conservation programs, as well as stricter regulations on fishing practices that may inadvertently harm shark populations. This incident has also prompted discussions about the potential for eco-friendly shark watching tours, which could provide educational experiences for the public while supporting conservation efforts.
Maintaining balance.
Sharks play an important part in the marine ecosystem. As apex predators, they contribute to the balance of maritime environments. Professor Wainwright stated that their presence suggests a robust marine ecology.
Seen one? Keep your distance.
If you see a shark, keep your distance and do not approach or try to catch it. NParks encourages anyone who see sharks not to approach or agitate them. If you are concerned, Dr Zeehan advises you to remain cool and move away carefully. Anglers are encouraged to release sharks that they catch. To avoid interactions with sharks, swim in groups and avoid being the only one in the water, especially around dawn or twilight, when sharks are most active, advised Prof Wainwright. He advised against swimming in murky water or after heavy rain, as these conditions can make it harder for sharks to identify what they see.
In light of the recent shark sighting, local authorities are considering implementing additional safety measures at popular beaches. These may include increased lifeguard presence, more frequent drone surveillance, and the installation of eco-friendly shark deterrent systems. However, marine biologists emphasize that such measures should be carefully evaluated to ensure they do not negatively impact the local marine ecosystem. Education remains a key component in promoting safe coexistence between humans and marine life, with experts advocating for more comprehensive public awareness campaigns about shark behavior and ocean safety.
