Dead wildlife

A Crabby Acquisition

Here at the museum, most of our specimens are collected from the research field, received through donations from other museums, or via reports of dead animals by the public.

In some instances, we also collect specimens through more ‘conventional’ means — the market! In fact, we often make it a point to visit local markets in our various field sites across Southeast Asia, as you never know what interesting critter will pop up. After all, the Sulawesi Coelacanth (Latimeria menadoensis), was discovered by Dr. Mark Erdmann in a Manado fish market while on his honeymoon!

Recently, Prof Peter Ng, LKCNHM head, collected an interesting specimen through similar means. He was having dinner at Turf City one evening when he came across an interesting live crab in one of the aquariums, and promptly bought the crab from the seafood joint. Saved from a certain fate of ending up on a dinner plate, the specimen was instead destined for the collection shelves at the museum.

This crab was later identified as a Golden King Crab (Lithodes aequispinus). According to Prof Ng, adults of this species can be as large, if not larger than their more famous counterparts, the Alaskan King Crab (Paralithodes camtschaticus).

Even though it looks crab-like, it is not a ‘true’ crab but actually related to hermit crabs. If you are confused, count the number of legs seen in this crab, and compare it with the mangrove mud crab, Scylla spp.  🙂

The crab’s origins were even more of a surprise as it was said to be from Korea, and if so, may be the first record of the species there.

Golden king crabs are not only found in East Asian waters which includes countries like South Korea, but can also be found in the Northern Pacific Ocean ranging from British Columbia in Canada all the way to Japan.

The crab is now awaiting final preparations at our laboratory before it is added to our wet collections along with other crustacean specimens. It will be invaluable as a future research specimen for comparative work and DNA studies.

The next time you visit a market, keep your eyes peeled out for interesting and unusual animals — they may be right under your nose!

Whale of a time at the Museum

The whale theme continues at the museum this week!

On 13 April 2016, we received a donation of the remains of a false killer whale from Underwater World Singapore (UWS). We are thankful for this generous donation and the support from UWS.

While news of the Singapore sperm whale has dominated the press since last July, little is known about Willy, the false killer whale that was stranded in Singapore more than two decades ago.

On 23 January 1994, two men who went crab hunting off Tuas spotted the whale, which they initially mistook for a shark. They alerted Underwater World Singapore (UWS) and the animal was identified as a false killer whale by UWS divers despatched to the site.

The Straits Times article about Willy’s stranding back in January 27 1994. 

News of the whale stranding spread and captured the nation’s imagination. The whale was dubbed ‘Willy’ by the press after the highly popular 1990s film “Free Willy”, a stirring story about a boy who befriends a killer whale or orca called Willy—which was captured from the wild—and sets him free.

Rescue attempts to move the whale into deeper waters spanned a week but were ultimately unsuccessful. Willy later went missing on 29 January 1994 and was found dead the next day by some fishermen. The UWS then collected the body to conduct a post-mortem and solve some of the mysteries surrounding her arrival and death.

Autopsy and Preservation at Underwater World

As the autopsy was underway, it turned out that Willy was an old adult female, and not a young adult male as first presumed. The cause of death was also identified as a combination of infectious injuries, old age and severe trauma as a result of being trapped in the bay.

Separated from her group, with numerous puncture wounds on the left side of her body, these were probable factors that caused Willy to seek shelter at Tuas. Willy was also found with an empty stomach, indicating that she was highly stressed at that point in time.

Willy’s body was later buried at Lorong Halus in Tampines. Her lower jaw with ten intact teeth was salvaged and preserved and used as an educational display at UWS.

Significant donation

What does this represent for us at the Lee Kong Chian Natural History Museum (LKCNHM)?

The donation represents another important and key addition to the mammal collection at LKCNHM. With the accession of this false killer whale specimen found locally, the mammal collection has been further expanded and we believe, would add to our knowledge of cetaceans in Singapore waters.

We hope that the evidence of the wonderful marine life in our waters will further serve as a reminder for future generations to treasure the rich marine biodiversity that surrounds our little red dot.

For more information on the story of Willy, you can find it at the Nature Society Singapore’s newsletter, The Pangolin, Volume 7, 1994.

A Roadkill Record of a Hairy-Nosed Otter from Selangor, Peninsular Malaysia

Dr Tan Heok Hui from the Lee Kong Chian Natural History Museum documented a roadkill of a hairy-nosed otter (Lutra sumatrana)

Unlike some of the more commonly encountered species of otters, the hairy-nosed otter is an elusive and rarely encountered animal throughout its native range in Southeast Asia.

The dead otter was a female 1.2m in length and its location was less than four meters away from the nearest water source, a black water creek running parallel to the road. the dampness of its coat of fur probably suggests that the otter met its end right after it left the creek and onto the road.

This record was recently published in the IUCN/SCC Otter Specialist Group Bulletin and you can read more about the article here!

Salvaging a Dead Sea Turtle at Changi Beach

[Salvaging a carcass is typically a disheartening affair, as we prefer to see our biodiversity alive. But it is always good to have some hope that the specimen we pick up would be able to contribute to science or allow others to learn more about our biodiversity. Here, Sankar A, our Toddycats SG50 intern, recounts his experience on a carcass salvage operation. – Marcus Chua]

I was just about to go home from work on 14 May 2015, when I saw a message on my phone from Marcus to the Toddycats, “Anyone on campus would like to head down with me for a carcass salvage?” Intrigued, I replied that I was free and could help out. 20 minutes later, I was climbing into a van heading towards Changi. I expected the carcass to be a roadkill, so it was a bit of a shock when Marcus told me that it was actually a Green Sea Turtle (Chelonia mydas). It was thought to have been hit by the propeller of a boat and had been split across its shell. NParks had kindly brought the carcass ashore and had kept it aside for the Museum to collect it.

The large sea turtle had been split across the carapace.

We drove over to Changi Beach Carpark 6, stopping only to pick up the taxidermists. We met Ruth Tan, NParks manager of coastal parks, who facilitated the salvage process and showed us where the carcass was held. After donning the necessary PPE (vinyl gloves and N95 mask), we carried the carcass over to a designated area, where the taxidermists could work. Despite the masks, the smell was pretty bad. The first thing we did was to take measurements and “crime scene” photos for record purposes. The turtle was large, with a carapace length of about 0.8 m. Marcus also ascertained that the turtle was a female, based on the short tail length. We took tissue samples from the carcass for cryogenic preservation. Since I had never taken a tissue sample before, Marcus showed me a couple of examples before allowing me to do one.

Is the haze back? Nope, just observing safety reguations!

As the taxidermists expertly prepared the carcass, structures of the turtle’s skeleton became apparent. I saw how the carapace (upper section of the shell) of the turtle was essentially formed out of a modified backbone and ribs like the specimen in the image below.

Because the boat’s propeller had split the shell in two, we were given a rare look into the cross-section of a Sea Turtle. It was genuinely a surreal experience. We were all thoroughly impressed by the speed and professionalism that the taxidermists exhibited.

Measuring the Sea Turtle’s carcass.

As the turtle was being deconstructed before my eyes, it occurred to me that this was the first wild Sea Turtle that I had ever seen. It was a pity that my first encounter with this rare creature had to be under such circumstances.  While there is an undeniable scientific and educational value of this specimen, it cannot possibly compare to the ecological value of such a large breeding female swimming in open waters.

Despite being internationally endangered, the fact that these turtles can be found in our waters never ceases to amaze me. Yet, they continue to be threatened by human activity, which this specimen serves as a grim reminder of. Nevertheless, it shows that we as humans have an important role to play in the conservation of such marine biodiversity.

Online database captures S’pore’s rich biodiversity

Online database captures S’pore’s rich biodiversity

Audrey Tan

A NEW online database has been launched compiling research on how Singapore’s flora and fauna interact with each other.

Called Animals and Plants of Singapore, it is managed by Lee Kong Chian Natural History Museum and went live on the museum’s website this month.

Users can click on an animal and find links to information on the plants or animals it feeds on – though work on the site is ongoing and not all species have links in place yet.

The database provides a name and a photograph of each species. For further information, users must click on the links to external sources, such as pages created by the National University of Singapore‘s life sciences classes, or the museum’s Singapore Biodiversity Records – an online collection of “flora and fauna in Singapore, including sightings of uncommon or rare species”.

Professor Rudolf Meier, deputy head of the museum, said the goal is to understand how different species interact to sustain Singapore’s green spaces.

“Animals and Plants of Singapore will track these interdependencies by linking species pages of prey and predators, or plants and pollinators,” he said.

“If we had a dedicated person or team doing the research, it would be as time-consuming as writing an academic paper for each species. But by tapping already-published research and observations, the site can be updated more frequently.”

Prof Meier hopes the site will make it easier for people to appreciate Singapore’s diverse ecosystem and give them a reliable source of information.

Data is cross-referenced with the museum’s stable of experts before being uploaded, and the site lists the names of the experts who identified the species.

The database now records more than 1,000 species of plants and animals, but Prof Meier hopes to more than double this figure by the end of the year. He estimates that there could be between 50,000 and 100,000 multicellular plant and animal species here.

Studies are under way to establish this, such as Singapore’s first comprehensive marine biodiversity survey, led by the National Parks Board (NParks). It began five years ago and is expected to be completed by May this year.

Dr Lena Chan, director of NParks’ National Biodiversity Centre, said: “Biodiversity databases are very important as they are historical records of plants and animals. These databases can be set up only if long-term monitoring surveys are carried out.”

She said the museum’s new database will complement NParks’ records, including its online Biodiversity and Environment Database System, which was started in 2011 and records 5,000 species of flora and 750 species of fauna.

“Together, we can generate greater awareness and appreciation of the rich biodiversity that we have,” she said.

A carcass washed up at East Coast Park beach and what happened next got everyone excited

[Note: Images of decomposing carcasses are found in this post]

A carcass of an unidentified vertebrate washed up at East Coast Park (ECP) beach on 15 Jul 2014. A park user who noticed the remains notified NParks.

NParks staff verified the report and passed the message from the Parks division (Liew Qi) to the National Biodiversity Centre (Cheo Pei Rong), to the LKCNHM collections manager, Kelvin Lim, then to me. By now, it was being referred to as a cetacean carcass (dolphin or porpoise).

On the morning of 16 Jul 2014, I went down to ECP to check and retrieve the carcass. There, it was confirmed to be indeed a cetacean as the skull, flippers and tail fluke was visible, but in an advanced state of decomposition.

The decision was then made to retrieve the carcass. The body, which was almost as heavy as me, was bagged with the aid of two very helpful NParks staff, Tan Wen and Jan Tan (who was on her second week on the job).

As the carcass was too big to fit in a car, Department of Biological Sciences (DBS) graduate students, Maxine Mowe, Liew Jia Huan and Ng Ting Hui, helped by facilitating a pick up with the department’s vehicle from fieldwork at Marina Reservoir. Ting Hui kindly drove the carcass to the museum.

Back at the museum, the sense of excitement (it was a rare salvage after all) was enough to motivate the museum folk to brave the stench for a peek at the carcass while it was prepared for bone preservation by Kate Pocklington and myself. Some bits of tissue was frozen for the cryogenic collection. Kelvin quickly selected skulls from the Zoological Reference Collection as comparative material. The carcass was then identified to be an internationally threatened Irrawaddy dolphin (Orcaella brevirostris) measuring approximately 2.2 m. Tammy Lim and Kho Ziyi documented the process, and we all smelled like dead cetaceans at the end of the day.
