Hello everyone! We have exciting news to share with all of you — we have collaborated with NUS Libraries to launch the Biodiversity Library of Southeast Asia (BLSEA).

blsea_poster-A3_5

BLSEA is an online resource that allows people all over the world to access digitised versions of biodiversity publications that are focused on Southeast Asia. This includes old publications from the museum, such as the Bulletin of the Raffles Museum, as well as many others.

Raffles Bulletin of Zoology – New Year, New Blood

With each new year comes new changes, and this year brings in some significant changes in the editorial team of the Raffles Bulletin of Zoology (RBZ), a peer-reviewed, open-access journal published by our Museum.

The Bulletin has a new Managing Editor – Dr. Jose C. E. Mendoza (a.k.a. “JC”), who had previously served as Associate Editor for Carcinology since 2013. Dr. Mendoza breaks the news to the community in his first RBZ editorial (read more here).

The previous Managing Editor, Dr. Tan Heok Hui, has taken a new portfolio in the Museum, that of Head of Operations, but is also staying on as an Associate Editor for Ichthyology.

Among his notable achievements during his 6-year term is the publication of five volumes (vols. 59–63) and 11 supplements (nos. 24–34), containing 458 articles and monographs – some of which have gone on to be among the most highly cited in the Bulletin’s history. Dr Tan has also ushered the Bulletin into modernity, publishing its first fully electronic volume (vol. 62) in 2014.

Copy & Production Editor, Mr. Jeremy Yeo, who has efficiently performed administrative, copy-editing and production duties since 2013, has also moved over with Dr. Tan to the Operations department of the museum. We thank them for their service and wish them all the best in this new stage of their careers!

Also joining the editorial team are Dr. Hwang Wei Song, as Assistant Managing Editor and concurrent Associate Editor for Entomology; new Associate Editors, Dr. Evan S. H. Quah (Herpetology) and Dr. Toh Tai Chong (Marine ecology & conservation); and new Copy & Production Editor, Ms. Clarisse Tan. Welcome aboard & good luck!

Visiting Scientist Feature: Dr. Tsunemi Kubodera

Three years of planning, and multiple expeditions consisting of sitting in the dark depths of the deep sea for around eight hours, enclosed in a small submersible. It took all these extensive efforts (and more) for Dr. Tsunemi Kubodera to become the first person to photograph and capture footage of the legendary giant squid (Architeuthis dux) in its natural habitat, 900 m underwater.

When asked about his feelings upon seeing the giant squid live in front of him for the first time, Dr. Kubodera said that he remembers being really excited while viewing the giant squid in the dark through a camera monitor, and being so eager to see it for himself.

“I really wanted to see it with my own eyes (and not just through the monitor),” he said.

Thus, he asked the pilot of the submersible he was in to switch on its bright lights, despite knowing that there is a risk that the giant squid may be scared off by the lights. However, the squid did not flee, but instead continued to feed on the bait that they used to lure it in, allowing Dr. Kubodera to watch it live for a total of about 23 minutes.

Dr. Kubodera, a zoologist from the National Museum of Nature and Science, Japan, is currently here on a research visit to help identify squid beaks that were found in the stomach of our sperm whale. Over the past few days, he has been working with our Mammal Curator, Mr. Marcus Chua, to identify around 1,800 squid beaks.

Over the weekend, in conjunction with the launch of our new exhibition “Out of the Water” and book “Whale out of Water”, there will be a public talk by Dr. Kubodera, where he will share his journey towards photographing and filming the giant squid. All seats have been filled as of press time.

The new exhibition features displays and stories on the giant squid, sperm whales as well as other marine creatures. The book “Whale out of Water” documents the journey we took from recovering our sperm whale, to putting her skeleton up for display in the gallery.

We look forward to seeing you here!

We also thank Dr. Kubodera for telling us interesting insights about his giant squid journey, and hope to see him again!

Visiting Scientist(s) Feature: Dr. Stefano Cannicci and students

Just before the Lunar New Year break, we hosted Dr. Stefano Cannicci from the University of Hong Kong, along with his PhD students, Rebekah Butler, Laura Agusto and Pedro Juliao Jimenez, who were here to examine crab specimens in the Zoological Reference Collection (ZRC).

Having brought over crab specimens they collected from Hong Kong, they came to familiarise themselves with the process of identifying crabs, by comparing their specimens to those in the ZRC.

Their 6-day visit brought along a few surprises, such as finding two new species of crabs among their specimens, a discovery that also excited the head of the museum, Prof. Peter Ng.

Small but Mighty

Dr. Cannicci and his students’ research interests are in marine biology and mangrove ecology, along with a focus on crabs. But why research on crabs in particular?

According to Laura, she became interested in studying crabs after learning how they play an important role in the ecosystem. Despite their small size, these creatures have a mighty effect on ecosystems such as mangroves, so much so that they have been dubbed ‘ecosystem engineers’ by scientists.

In order to seek protection from environmental extremes and predators, crabs dig burrows in the soil – long, winding tunnels in which they can seek refuge. These burrows also help to open up the oxygen-poor soil and allow oxygen to be better absorbed by the mangroves.

Two main groups of crabs that do so are the vinegar crabs (Sesarmidae) and the fiddler crabs (Ocypodidae). They also aid in nutrient cycling within the mangroves by consuming and also burying leaf litter, preventing nutrient loss and encouraging decomposition.

Mangrove Management

Just like the tiny critters that dig burrows in its soil, mangroves also play an important role in the ecosystem (see more here).

Dr. Cannicci and his students took the opportunity to visit Singapore’s own mangroves, and, with the help of local mangrove champion and LKCNHM research affiliate, Mr. N. Sivasothi, they were able to see Sungei Buloh Nature Reserve, as well as mangroves in Lim Chu Kang and Mandai.

Duly impressed that such sites still remain in Singapore, they, however, lamented the presence of trash brought over from the nearby sea, an all-too-common global phenomenon. They learned from Mr. Sivasothi (who is also the national coordinator for the International Coastal Cleanup in Singapore) that the trash was retrieved through clean ups.

Dr. Cannicci also cited the importance of outreach efforts to educate the public on the importance of mangroves, so that more can be done to preserve them and keep them in good condition.

A Good Example

On a similar note, he mentioned that our museum has done a good job in educating the public on natural history, with the exhibits presented in a way that are both interesting and easy on the eye. He also expressed his wish that there can be a similar natural history museum set up in Hong Kong.

We thank Dr. Cannicci for his kind comments, and look forward to see him and his students again!

Harryplax severus and the Twenty-year-old Secret

A secret that evaded detection for almost 20 years has finally been uncovered with the discovery of Harryplax severus.

Sorry to disappoint all the ‘Potterheads’ out there, but this is not a synopsis of a new Harry Potter spin-off. Rather, it is a tale of how a new species of crab was discovered by LKCNHM researchers, Dr. Jose C. E. Mendoza and Prof. Peter K. L. Ng, almost twenty years since it was initially collected.

Harryplax_severus_frontal_male paratype PR.jpgFrontal view; male paratype of Harryplax severus.

The new crab species (also in a new genus) was described in a scientific article, which was published in the journal Zookeys and made available to the public last Tuesday (24 Jan. 2017, local time). [see: https://doi.org/10.3897/zookeys.647.11455]

Seaside Exploration

The crab was found in the late 1990’s in the coral reef rubble on the Pacific island of Guam by Harry Conley, a former US marine. Mr. Conley started to frequent this western Pacific island in the 1980’s in search of seashells, but his forays into the reefs yielded not only seashells, but also crabs and other creatures, which formed a sizeable personal collection.

After Harry Conley’s death in 2002, his crab collection was presented to Prof. Ng by Dr. Gustav Paulay (then with the University of Guam) for further study. Many of these specimens were eventually shown to be new or rare species, with several resulting scientific publications.

Two small specimens, however, were somehow overlooked and would remain in the collection of the LKCNHM until they were re-examined in early 2015 by the museum’s crustacean curator, Dr. Mendoza. Together with Prof. Ng, they determined that the crabs belonged to a new genus and species based on several unique characteristics in their anatomy.

harryplax_severus_male-paratype-prDorsal view; male paratype of Harryplax severus.

This tiny crab (7.62 mm long by 5.08 mm wide) has adaptations such as small eyes, well-developed antennae, and long, slender legs, which help it feel quite at home in the dark cavities amidst the reef rubble.

Potterhead’s Wish

Why the name Harryplax severus, then?

Well, the genus name, Harryplax, was primarily chosen in honour of the crab’s original collector, Mr. Harry Conley, whose collection of ‘critters’ found in the rubble beds of Guam have contributed greatly to the field of marine science.

The name also alludes to a famous pop culture namesake, Harry Potter, the main protagonist of the fantasy novel series by J. K. Rowling, whose magical skills are likened to Mr. Conley’s ability to find rare and fascinating creatures.

The species name, severus (Latin for ‘harsh’, ‘rough’ and ‘rigorous’), highlights the tough and strenuous steps undertaken to collect the crab. Furthermore, it alludes to yet another namesake from the Harry Potter series, Professor Severus Snape, a character described by Dr. Mendoza as “notorious and misunderstood”. Just like how Professor Snape managed to conceal one of the most important secrets in the story, the new species of crab has also been able to evade discovery for almost 20 years since its initial collection.

A self-confessed ‘Potterhead’, Dr. Mendoza could not pass up the opportunity to name the new discovery after characters from the popular series, a move gamely accepted by Prof. Ng, who knew Mr. Conley personally and felt that he would have appreciated the connection.

We look forward to more interesting discoveries by Dr. Mendoza and Prof. Ng in the future!

[Research highlight] Molluscs for Sale: Assessment of Freshwater Gastropods and Bivalves in the Ornamental Pet Trade

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.

LKCNHM on the News: Great travel deals ignite wanderlust

The 42nd edition of the MATTA Fair in Kuala Lumpur featured a total of 1,212 booths by more than 900 exhibitors.

The Singapore Tourism Board marked its return to the fair after a three-year hiatus with a wide range of exciting travel packages.

“We’re taking the opportunity to introduce the latest attractions at the fair due to recent developments in Singapore,” said Singapore Tourism Board International Group Malaysia area director Serene Woon.

“Among them are the Lee Kong Chian Natural History Museum, which is also featuring three sets of dinosaur fossils, and the National Gallery Singapore, the largest venue for South-East Asian art.

“The idea is not only to offer families a fun holiday, but also an enriching experience for the children so that they learn something as well,” she explained.

Visit from old friends: the Orchards

We begin this month with another crustacean themed post — a report on the visit of Max and Beverly Orchard on their first visit to our new building!

Max was the Chief Ranger of Christmas Island National Park prior to retirement, and author of ‘Crabs of Christmas Island‘. Given his fondness of crabs, it was only natural that he and Prof. Peter Ng forged a strong collaboration. The Orchards have been a focal part of the Museum’s expeditions to Christmas and Cocos (Keeling) Islands from 2010 to 2012, culminating in a supplement in the Raffles Bulletin of Zoology highlighting the Biodiversity and Management Challenges of both islands. It yielded many new discoveries of crustacean species both on land and out at sea. See more examples from our old blog here.

Amongst the discoveries in the anchialine caves on Christmas Island, were two new species, named Orcovita orchardorum  and Orcovita hicksi. These two crabs were the first record Orcovita in the Indian Ocean and Australia.

It was a good afternoon of catching up, and planning future research trips to Christmas Island. We miss Christmas Island very much, and hope to be back soon!

Orcovita orchardorum was named in honour of the Orchards who have been dedicated their lives spearheading conservation initiatives to safeguard the island’s unique biodiversity.

Scientist Feature: The Malaysian Cave Rat Mystery

Ms Islahuda Hani Sahak & Mr Mohammad Amin Abdul Aziz

What do rats and mice have in common with guinea pigs and hamsters?

They belong to a group of animals known as rodents. Rodents contain some of the biggest families within the animal kingdom.

In this edition we feature PhD candidate from the University of Malaya (UM), Ms Islahuda Hani Sahak, who is working to identify rodent skulls in Malaysian caves. She hails from the Department of Geology, Faculty of Science at UM.

Assisting her in this trip is Mr Mohammad Amin Abdul Aziz, who is her husband, and also a trained geologist. For this research trip, the goal is to investigate differences between collected skulls to aid in species recognition.

This study is the first comprehensive survey in Malaysia of how the Muridae fossil group plays an important ecological role in the Quarternary geological time period.

Understanding the paleo-environment

Their visit to Lee Kong Chian Natural History Museum (LKCNHM) in April 2016 involved comparisons between full-bodied specimens found in our collection and Ms Islahuda’s rodent skull fragments.

This is a bonus as Ms Islahuda often only has dentition to go by, as it is rare to get a complete skull of fossilised rodents with their teeth intact. Differences are often minute as there are many similarities in morphology (form).

They are now one step closer to determining the identities of their subjects. Ms Islahuda managed to narrow it down to four confirmed genera: Niviventer, Rattus, Maxomys and Chiropodomys. On an even better note, she has established one of the species as the Indomalayan pencil-tailed tree mouse (Chiropodomys glirodes).

There are many aspects that both Mr Aziz and Ms Islahuda find interesting about rodents. For example, the skulls of rodents can be used to determine their age and even their diet, which gives insights to how each species differs and how adaptable they can be.

Ms Islahuda explains that geologists try to reconstruct the paleo-environment to get a glimpse of what life was like millions of years ago. Clues such as fossilised remains of animals found in river sediments often indicate what living conditions were like millions of years ago. Rodents are the perfect study subjects as they do not migrate and live in specialised regions.

Raising the flag for environmental conservation

Their reasons for conducting this research are based on a conservation mantra.

They hope to raise awareness of cave fossil conservation by creating an environmental value for cave ecosystems to protect them from threats such as the construction of temples and collection of bat guano or poop for plant fertiliser.

They attempt to educate people in appreciating this often-misunderstood group of animals. Pest such as brown rats and house mice are only a tiny minority within rodents which cause harm to humans. On the other hand, hundreds of other species play important roles in their ecosystems around the world.

For example, did you know that jungle rats such as the Rajah’s spiny rat – found in our region – help in the seed dispersal of trees which promote the health of the forest? Rodents are also the favourite prey for animals such as snakes and owls!

This was Ms Islahuda’s and Mr Aziz’s first visit to LKCNHM. As part of their investigation they will also head to the natural history museums in Indonesia, Thailand, China and London to seek more answers in solving the identities of their specimens.

LKCNHM is honoured to host researchers and regional experts who contribute to our knowledge and understanding of Southeast Asian biodiversity. These scientists play an integral part in spearheading environmental conservation initiatives that protect native ecosystems.

We wish Ms Islahuda and Mr Aziz success as they continue in their search to determine the mysteries of the elusive rodents of Peninsular Malaysian caves.
