With 1,900 members now, the Facebook page has also become a repository of information for researchers.
“With more divers posting in the group, we get to … discover that some of the critters (photographed) can be new records for Singapore,” says environmental volunteer Toh Chay Hoon, 47, a group member who specialises in identifying sea slugs.
“New records” refer to wildlife with a known scientific name, but which had never been sighted in a certain area before.
One such discovery Toh helped to identify was the nudibranch, Trapania scurra, which diver Lim Chee Ying photographed in March near Pulau Hantu. The new biodiversity record was later published in the journal, Nature in Singapore.
