The museum’s deputy head, Prof. Rudolf Meier, published an opinion article about how the current citation practices in biology are unfavourable to taxonomy.
Citations are important in science because it gives credit to the original authors (scientists) who made and reported a particular discovery or idea. However, authors of species are seldom cited in scientific publications. To address this issue, some journals or publishers require full citation of species descriptions.
Meier opined that citing and using original species descriptions may be inappropriate or lead to wrong conclusions. For example, the original description of the commonly eaten flower crab (Portunus pelagicus) by Carl Linnaeus in 1758, actually comprises four species today.
Instead, he argues that “proper citation credits should instead go to the literature that was used for specimen identification and the publications that contain the most accurate information on the currently accepted species limits of the species under study”.
Read more about his thought on this issue in the original paper.
This new species of pea crab, Serenotheres janus, is named after the Roman two-faced god, Janus, as it has an unusually-shaped carapace that looks like two sides of a tent when seen from above.
The museum’s head, Prof. Peter Ng, and Dr Christopher Meyer from the Smithsonian Natural Museum of Natural History, United States of America described the crab from a large date mussel collected from Solomon Island.
The crab lives inside (and are parasites of) the date mussel, Leiosolenus obesus, which resemble date seeds. These mussels burrow into coral rock for protection. Thus, the crabs live a doubly protected lifestyle inside a mussel that lives inside a rock.
Currently, only one specimen of Serenotheres janus is known, and it certainly shows that it pays to look into every nook and cranny (and every shell) for undiscovered life!

Did you know that a large number of snails and clams come into Singapore via the ornamental pet trade?
NUS Phd student, Ng Ting Hui, and researchers from the Lee Kong Chian Natural History Museum and Department of Biological Sciences at the National University of Singapore found a total of 59 species of snails and bivalves had been brought into Singapore via the pet and ornamental animal and plant trade from 2008 to 2014.
Some of these are known or potentially invasive species which may cause harm to species that are native to Singapore, or to the environment. This study provides an important baseline and reference for future monitoring, and points the direction towards a more sustainable ornamental pet trade.
The findings of the research was featured on the Straits Times by Carolyn Khew on 4 Nov 2016.

While Pulau Tekong is an island familiar to many in Singapore as home to the Basic Military Training Centre (BMTC), what is less known is the island’s importance for wildlife.
Realising this, researchers from the Lee Kong Chian Natural History Museum and the National Institute of Education compiled a checklist with notes on the freshwater fishes, amphibians, reptiles, and mammals of Singapore’s largest natural offshore island.
In all, 18 species of freshwater fishes, 15 amphibians species, 45 species of terrestrial reptiles, and 31 species of terrestrial mammals were recorded. Some species such as the Kuhl’s gliding gecko (Ptychozoon kuhli), and brown tube-nosed bat (Murina suilla) are known from Singapore only from Pulau Tekong.
Additionally, several nationally rare and threatened species such as the Jasper’s cat snake (Boiga jaspidea), leopard cat (Prionailurus bengalensis) and Sunda slow loris (Nycticebus coucang) are also present, or are thriving on the island.
Pulau Tekong’s use as a restricted military area appears to have also served to conserve wildlife on the island well. It is hoped that substantial areas of natural vegetation is maintained, and that its rich biodiversity is taken into consideration for any development planning. This will help insure the survival of the island’s interesting and nationally threatened fauna.
Earlier this week, we hosted a research visit by Mr. Arlo Hinckley Boned, who came to collect data from the mammals in the Zoological Reference Collection.
Arlo hails from the Conservation and Evolutionary Genetics Group of the Doñana Biological Station in Spain, and is working on the diversity of shrews and gymnures across biogeographical realms for his Phd thesis.
He recently completed four months of fieldwork in Borneo, sampling areas in Sabah, Malaysia, for small mammals. During this period, he shared that he lost a total of 9 kg from the intense fieldwork, but gained interesting insights on the distribution and diversity of the mammals there. Arlo maintains the Small Mammals of Borneo blog with his colleagues where they share about small mammals and their field experience.
As his research group is particularly interested in the diversity of vertebrates in the Sunda shelf, Arlo also examined specimens of the red giant flying squirrel (Petaurista petaurista) in addition to gymnures and moonrats. On his last day, Arlo was particularly excited to come across a red giant flying squirrel specimen collected by Charles Hose, a prominent zoologist and British colonial administrator.
We wish Arlo all the best for the rest of his work in the region.
A new discovery by museum scientists and their collaborators of an introduced snail in Singapore was recently published in Occasional Molluscan Papers. We asked them to tell us more about the significance of their findings:
History is repeating itself. Another alien snail—Cryptozona siamensis—has made its way to Singapore. Several months ago, this species, which is native to Thailand, was recently found in Singapore. The snail is believed to have been accidentally introduced through horticultural trade activities. Presently the snails appears to be confined to a single locality in Mandai, which was formerly a plant nursery.
This follows the 2011 discovery of Limicolaria flammea (a native of East Africa), in Singapore. Despite efforts to prevent the spread of that earlier invader, the snail is now found across Singapore.
The discovery of both species highlights the importance of being able to tell different species apart (also known as taxonomy). Both non-native snails superficially resemble species already known from Singapore. They may have gone unnoticed for much longer if researchers had not been actively studying Singapore’s fauna.
Although the introduction of a snail may seem harmless, it is known among researchers that introduced species can pose a threat to native biodiversity greater than most people realise. Worldwide, many native species are endangered because of the negative impacts brought about by introduced species. Besides being a possible plant pest, studies in Thailand have shown that Cryptozona siamensis can carry parasites that may infect humans; usually occur through ingestion of raw or undercooked snails or contaminated vegetables.
So far in Singapore, Limicolaria flammea has not done the same damage some of its close relatives have wreaked in other parts of the world, and the situation for Cryptozona siamensis is as yet unknown. While the news of yet another introduced species is typically bad news, there are documented cases of successful eradication of introduced species in other countries, especially if discovered quickly and action is promptly taken. In additional to physical removal and the tightening of measures to prevent accidental importation of non-native species, the public can play a big role by getting to know the local fauna and to keep an eye out for invaders. It is hoped that the relevant authorities will step up efforts to eradicate this snail based on the precautionary principle.
Let us do what we can to prevent history from repeating itself.
