(1874) Early
17th century navigational maps indicate that Chinese tributary missions during the early
Ming Dynasty, conducted between 1405 and 1433, and possibly led by Admiral
Zheng He, have been theorised to have sailed near Pulau Satumu. If so, this would be one of the earliest references made to the islands in the region. Two of the very first written descriptions of the Rabbit and Coney islands were done by
John Crawfurd during a diplomatic journey from India to
Siam and back in 1822 aboard the
John Adams. On 19 January, he said he sailed along the narrow channel that separated the islands, and he likened the area to being edged with green, verdant isles. On the homeward journey on 23 November, Crawfurd and his companions landed at an adjacent island, collecting botanical specimens and remarking on the profusion and novelty of the country's plant life.
Nathaniel Wallich's report is considered to be the first recorded natural history sighting of the islands around Coney Island. In the same time period, on 31 October 1822, William S. Collinson, John Croft Hawkins and
Robert Moresby, aboard the
Prince of Wales, also mentionedthe Coney and the Rabbit in their pilot book for entering the Straits of Singapore by the northeast passage. The Rabbit and the Coney were mentioned again in connection with Crawfurd's circumnavigating survey of Singapore and the surrounding islands in August 1825. Described in the
Singapore Chronicle in November of the same year, the survey reported the islets as "two masses of sandstone with a few trees." The expedition concluded with the arrival of the survey party at the two islets, but the subsequent ceremony marked the start of something new, an almost hundred and fifty years of colonial presence. During that visit, the party fell on the Rabbit and Coney and formally took them into possession with a
21-gun salute. The islets, by now familiar to navigators, were declared the southwestern boundary of British dominion, extended, it was claimed, a full one hundred geographical miles in circumference. Only two significant natural history-related trips to Coney Island existed prior to the construction of the lighthouse. Geologist-explorer
James Richardson Logan and surveyor
John Turnbull Thomson each noted the geology of the island on their travels. In 1958, Hans and Lotte Hass, ocean biologists, shot the islet for their underwater footage, seen by millions. The reefs are still among the most pristine in Singapore waters, though with a slight decline in the percentage of coral cover over the decades. The rest of the marine lifeon and around the islet is still under-researched, though plenty has been done. Due to reclamation activities which affected other islands in Singapore, Pulau Satumu gained an artificial lagoon and grew by approximately one hectare during the 1970s. The islet and its immediate vicinity are today a restricted area normally closed to the public. Pulau Satumu and nearby Pulau Biola were designated as priority marine conservation sites under Singapore's Blue Plan 2018. == Raffles Lighthouse ==
