SINGAPORE: It could take "up to several weeks" before the
rotting carcass of the sperm whale that washed up on Singapore's
shores is fully dissected and brought indoors for further
examination, staff from the Lee Kong Chian Natural History Museum
(LKCNHM) said.
The main risk: The high
likelihood of the whale's decomposing innards exploding, said Mr
Foo Maosheng, curator of the cryogenic collection at the
LKCNHM.
When Channel NewsAsia visited
the location of the carcass at Tuas South on Saturday morning (Jul
11), staff from the museum were seen inserting a straw-like metal
rod into various parts of the underside of the whale's belly. This
was meant to allow the built-up gas in the belly to be released
slowly and safely, Mr Foo said.
"We are now working to extract
the part that decomposes fastest: The gut," he said. "First we are
releasing air from the gut - it's well known that the gut of a dead
whale can explode."
"It's hard to tell how long it
will take. This is our first time doing anything like this, it
could take at least a week to several weeks to deflesh the whole
thing," Mr Foo added. "We are not working through the night. Its
not safe to work overnight. It's a biohazard. And there's not much
light, we need to stay safe."
Apart from preserving the skeleton for possible display, Mr Foo
said they also plan to extract some tissue for DNA tests as well as
study the contents of the whale's stomach, which could give some
clues on the whale's final days and the route it took to
Singapore.
The bloodied carcass of the
sperm whale was spotted off the coast of Jurong Island on Friday
morning. The whale was finally brought to shore at 9.15pm on Friday
evening, after an operation involving various government bodies,
including the Maritime Port Authority and the National Environment
Agency, who pitched in to help staff from the LKCNHM salvage the
carcass.
The age and gender of the
whale are not yet known.
"We can't tell it's age for
sure but it's young," said Mr Foo. "Males can grow up to 18m. This
is 10.6m. We can't tell if it's male or female - the genitals are
hidden away."
