Update: here's a view of the oil rig taken on 7 Jul 08 during our trip to Pulau Hantu.

The oil rig taken from Pulau Hantu.
Taken on the way home with indications of the locations of Pulau Semakau, Raffles Lighthouse (RLH) and Pulau Senang. Raffles Lighthouse and the Live Firing Islands of Sudong, Pawai and Senang have some of the last untouched reefs in Singapore. While Pulau Semakau has good natural shores. Let's hope this massive activity does not impact these nearby reefs.
A closer look at the oil rig.
Here's a photo of the oil rig taken on Pulau Semakau on 3 Aug 08

The work period was extended to September in a follow up notice. More on the wild shores of singapore blog.

Kiasi Krab on Changi

3.30am and we're back on the shores, this time at Changi for the super low tide. This narrow but favourite shore of ours is just teeming with life!There are at least five creatures visible in this photo, can you spot them all?OK, some of them are really tiny like the snapping shrimp and little hermit crab, in addition to the bigger sand star, peacock anemone and brittle star.

The seaweeds are in fact, crawling with all kinds of tiny creatures.There countless tiny crabs. And I saw one tiny sea urchin. This is one reason why we should avoid stepping on thick growths of seaweeds.

Here's another crowded photo with another five visible animals.
Besides the tiny little fishes, it's easy to overlook the big spiral melogena snail whose shell is well camouflaged, Its little black siphon is sticking out of the shell tip.

Here's another photo of what seems to be big sea anemone and sotong.But the sotong turns out to be an octopus!It had arranged its arms around its large head! Here he is spouting water.When he decided to move, he looked more obviously like an octopus!

The octopuses on our Northern shores look different from those we see on the Southern shores. The Northern octopuses have big heads (relative to their shorter arms) and don't seem to change their skin textures to become spikey or 'hairy' like the Southern octopuses. We still don't know the identity of both of these kinds of octopuses.

Peacock anemones seem to be a favourite hangout for other marine life. Around the tube of this retracted peacock anemone were lots of little black spirals of phoronid worms. And a little bristley brittle star was nestled among them.

For some reason, this morning I saw at least three peacock anemones with elbow crabs next to them.This peacock anemone has two elbow crabs nearby. The crabs are well camouflaged: there's one on the upper right corner, and another in the lower middle portion of the photo.

Another fascinating animal is the fan worm. It is a segmented bristleworm with a fan of feathery tentacles on its head. It builds a tube that it lives in.This particular kind of fan worm is common on Changi, but I seldom see it elsewhere. You can see the segmented body of this worm, with tiny little bristles on segments. It has a delicate fan of feather tentacles which are banded blue and orange with tiny spots.

For unknown reasons, this kind of fan worm is often seen at low tide with its fan held in four 'petals' so it is often mistaken for a flower.I have no idea why the worm behave in this manner. Other kinds of fan worms don't do this.

Special finds this morning include the Miliaris cowrie (Cypraea miliaris). Can you see it?I don't blame you if you can't. This snail covers its shell with a part of its body (called the mantle) which has lots of projections. It looks more like a slug when it does this. I didn't find it and it was Super Slug Seeker Chay Hoon who found it.

With the mantle retracted, the beautiful shell is seen.This pretty cowrie is listed among the threatened animals of Singapore, mainly due to habitat loss and over-collection. I haven't seen it for some time. So it was a relief to see several of them this morning.

Changi of course is just splendid for sea stars. And there were lots and lots and LOTS out this morning! Of various species and sizes. Aren't they beautiful?!More about telling these kinds of sea stars apart.

Sea stars encountered today included the Cake sea star (Anthenea aspera), Biscuit sea star (Goniodiscaster scaber), Gymnanthenea laevis and of course the Sand star (Astropecten sp.), Nepanthia sp. and the Rock star (Asterina sp.).

And today, we also saw the Transparent sea cucumber (Paracaudina australis)! It's been a long time since I've seen one.The sea cucumber is smooth and indeed so transparent that you can see its internal body parts!It has tiny stubby smooth feeding tentacles.

Other sea cucumbers seen include lots of ball sea cucumbers (Phyllophorus sp.), smooth sea cucumbers, thorny sea cucumbers (Colochirus quadrangularis), some warty sea cucumbers (Cercodemas anceps), and stuck on hard surfaces the unidentified orange sea cucumbers.

Of course a seahorse should always be a special find.But we are seeing them so often these days that we are not appreciating them enough I fear.

Here's some stuff I've never seen before.

I've often seen the shell of this snail, usually with a hermit crab inside. But I've never seen one alive yet.This one was very much alive and doing something, we don't really know what. It might have been eating something or laying eggs. We waited until it stopped before having a closer look at it.Here's what it looks like from the under and upper side. I don't know what kind of snail this is.

And here's a really odd sight. Out of water and lying limp, these seem to be some kind of anemone or anemone-like animal.Here's a closer look at the strange tentacles with ball-shaped tips.The tentacles surround a conical mouth-like structure. I have absolutely no idea what it is!

And just before the tide turned, I spied a strange anemone I've not seen before.It had a body column that was 'hairy' and its tentacles were short.

Even more remarkably, as I tried to take a photo of it, it started to MOVE! It was only then that I realised that the anemone was attached to a shell occupied by a hermit crab.
But the hermit crabs was so TINY compared to the gigantic sea anemone!!Here's a closer look at the sea anemone and the hermit crab.

The sea anemone probably protects the hermit crab from predators like the octopus. If so, this hermit crab is truly extremely kiasi to have such an outsized anemone.

Alas, this marvellous shore is somewhat impacted by careless shore users.There was this patch of assorted 'rubbish' including litter and half dead animals. Possibly dumped by a collector who changed his mind. The shore was also pock-marked by holes dug up probably by fishermen looking for worms.

Pasir Ris: some mysterious finds

3am and Chay Hoon and I decide to check out the rest of the large Pasir Ris shore. There's larger patches of seagrasses there!The shores are rather soft, but teeming with life. In the rather clear waters of this last of the morning super low tides, there are swimming crabs, sea stars and hermit crabs.Lots of hermit crabs! In huddles here and there. Hmm, I wonder what they're up to?

And a super abundance of sand stars (Astropecten sp.).
In various sizes from tiny to large.For some reason, I saw a lot of them upside down today. I also saw the remains of a disintegrated star. Was it attacked? Or is something else happening to them? There were also many with lost arms, like this poor star with three regenerating arms.

The masses of black short-spined sea urchins (Temnopleurus sp.) was seen again.These sea urchins 'carry' stuff like shells, which is why there are so many clam shells among the sea urchins. I'm not sure why they gather in groups like this. They seem rather smaller than usual for it to be for mating. Possibly for protection?

A mystery echinoderm was this purplish sea cucumber in the middle of the sand flat.I have no idea what it is.

And a mystery fish!It has a very long first dorsal fin and pretty colours on the tail and the rest of the dorsal fin. I tried to take a closer look at it but the fish disappeared into a burrow as soon as I approached.

There were also several of these large beautiful shells on the shore.The shells are empty. I have no idea what kind of snail made this shell and where they live. In deeper water? Burrowing in the sand?

Another puzzle were these clumps of bubbles on the sand. Several were seen, like delicate glass ornaments.

Another glassy marvel is this beautiful sea anemone which I call the glass anemone because it reminds me of blown glass.It's also sometimes seen on our other northern shores. It is one of our common sea anemones that have yet to be identified.

This soft shore is full of all kinds of different anemones. Including this odd little dark anemone that I've not seen before.
A closer look reveals rows of bumps along the body column.And pretty yellow spots in the centre on the oral disk, as well as along the short arms.

These soft shores remind us very much of Changi. As in Changi, there were also some peacock anemones with attendant black phoronid worms, several small and large carpet anemones some with tiny shrimps in them. The sea pens are not abundant here, I saw only one stick-like Virgularia sp. Also missing were brittlestars, biscuit sea stars, thorny sea cucumbers and mantis shrimps that we regularly see on Changi. Although there were lots of sand collars, I didn't manage to find any living moon snails.

There were not many moon crabs (Family Matutidae) at Pasir Ris. I saw this rather 'weedy' moon crab. It was still alive, although it wasn't very lively.Its body was not only overgrown with seaweeds, but also had other little animals living on it. I'm not sure what's happening. Is the poor crab sick? Paratised by some nasty parasitic barnacle? On Changi, we usually see this situation more on the swimming crabs and not the moon crabs.

There were several Sentinel crabs (Macrophthalmus sp.) on the shores.In the same larger group as fiddler crabs, these crabs also have eyes on long stalks. But their pincers are equal sized.

Further up on the higher shore, there was this other crab in a burrow, also with long eyestalks.Is it also a Sentinel crab or some other crab? I have no idea.

And what a lovely surprise to come across a seahorse (Hippocampus kuda)!A very pregnant papa seahorse he was!

Chay Hoon found SIX of these little black yellow-spotted Gymnodoris nudibranchs!
These little nudibranchs require a keen eye to spot as they are tiny and well camouflaged.

She also found several of these odd looking flatworms.There were lots of them out and about this morning. Even blind me saw some of them. The odd thing about them is the pair of 'tentacles' sticking out of the body. I have no idea what kind of flatworm this is.

We had a pair of these flatworms in the box to take closer photos of them ...Suddenly the little one attached itself to the big one and a tangle of twisting ensued. Oops. Possibly there is something going on to do with baby flatworms?

Flatworms are hermaphrodites. Each flatworm has both male and female reproductive organs. So when two flatworms meet they can exchange sperm. Shortly after twisting about for a while, the two flatworms calmly separated and moved off in separate directions.

Wow, what a fantastic morning out on the shore. More questions than answers, but that goes to show how much more there is to learn and discover about our shores!

As we were exploring, a friendly passerby with a plastic bag approached us. We showed him some of the fascinating marine life there. We asked about the contents of his bag and he showed us a dead fish, several hermit crabs and sea stars. He intended to try to use them as bait, 'for fun' in his fishing later on at high tide. We persuaded him to return all the other marine life and just use the dead fish. He was very friendly and agreed to do so.

Scientific names for sale

Want scientific immortality? Name a sea worm
Alicia Chang, Associated Press Yahoo News 30 Jun 08;

Jeff Goodhartz is single and has no children. But he wanted to ensure the family name would live on after he's gone.

So he paid $5,000 to have a newfound sea worm given the Goodhartz name, "goodhartzorum."

"This really jazzes me up," said the 55-year-old high school math teacher whose namesake is translucent with a flamboyant blue tuft. "It will be out there, the family name."

And it will be swimming in the Belize mangroves where someone else discovered it.

Goodhartz bought the naming rights from the Scripps Institution of Oceanography, which unveiled its name-a-species program earlier this year. This modern twist on taxonomy is a way to raise research money, and lots of groups have been doing it.

But its growing popularity has rekindled a debate over whether the practice invites fake discoveries and has led to a push for oversight.

"It is conceivable that someone could fabricate a new species in order to make money, if it were shown to be lucrative," said Andrew Polaszek, an entomologist at the Natural History Museum in London.

Taxonomy ranks among the world's oldest professions, dating back to 18th century Swedish botanist Carl Linnaeus, who popularized the classification system still in use today. Of the 30 million or so species of animals, plants and microbes on Earth, only about 1.8 million have been named and identified so far.

Traditionally, the discoverer gets to christen the new organism. All living things have a two-part scientific name, usually in Latin. It's common for discoverers to name a new species after themselves or in honor of their spouses, children, colleagues, benefactors or even celebrities.

In recent years, species names have gone from finders keepers to being auctioned off or sold to donors to support research as other funding has dried up. Not all species are created equal. The rarer and more evolved the organism, the more money it tends to fetch.

Doug Yanega, an entomologist at the University of California, Riverside, wants a clearinghouse to review and publish animal names. Right now, species monikers are scattered across scores of scientific journals — some with weaker peer review than others.

Global efforts are under way to catalog species, but they tend to sort out existing names and compliance is voluntary. The Census of Marine Life, which chronicles sea animals, last week confirmed 122,500 marine species names so far and 56,400 aliases — different names that have been given to the same species over the years.

Yanega has no problem with credible scientists selling naming rights to fund their work, but he fears unethical people could see this as a moneymaking scheme.

"The potential for abuse is still too large," Yanega said. "It's too easy to do an end-around and exploit the system."

Most researchers say faking species names is a rare occurrence, but that could change if it became profitable.

The International Commission on Zoological Nomenclature, which publishes rules on animal names, doesn't have a position on the matter, said Ellinor Michel, who heads the group.

At Scripps, before an animal is put up for sale, researchers run a background check in scientific journals and perform DNA tests to make sure it's unique.

"We wouldn't offer a species name unless we're absolutely certain it's never been described before," said Scripps curator Greg Rouse, who had an Australian feather-duster worm — Pseudofabriciola rousei — named for him by a colleague.

Rouse is also the discoverer of Goodhartz's featherworm. Rouse found it in an underwater mangrove while snorkeling off the coast of Belize two years ago. It is not only a new species, but part of a new genus of Belize featherworms too, he said.

Though the species will be called goodhartzorum, Rouse is still deciding the genus name.

Among the more successful conservation groups to sponsor species names is the German nonprofit Biopat, which has raised $700,000 since 1999 for biodiversity research through the sale of more than 100 species ranging from frogs to beetles to spiders.

Several recent high-profile online auctions have put a spotlight on naming rights.

In 2005, the Wildlife Conservation Society raised $650,000 for a new monkey species in Bolivia. The primate was named after the highest bidder, Internet casino GoldenPalace.com, known for all sorts of oddball purchases including a grilled cheese sandwich half that the owner claimed bore the image of the Virgin Mary.

The monkey's scientific name — Callicebus aureipalatii — is Latin for "Golden Palace," but it's informally known as the "GoldenPalace.com Monkey."

Last year, the Florida Museum of Natural History netted $40,800 from an anonymous donor for a novel Mexican butterfly species. The insect was named after a deceased Ohio mother of three sons who fought in World War II.

Zoologist Jon Norenburg of the Smithsonian's National Museum of Natural History has nothing against the species name trade since taxonomy is steeped in vanity and selling names falls into that tradition. But he warned that someone's preferred name may not always pass scientific muster.

"Donors need to be aware that there's the possibility that their name could get sunk," he said. "It's kind of like financial investing. You need to ask, `What's the fine print?'"

Besides the Belize featherworm, Scripps also has sold a $5,000 Australian featherworm to a woman who planned to name it after her husband as an anniversary gift, and a $10,000 spiny worm to cell phone maker Nokia Corp.

Nokia spokeswoman Jackie Evory said the company held a contest and will Latinize the winning entry, which happens to be its slogan, "Connecting People."

Still up for grabs is a $15,000 sea slug, a pair of bone-feeding worms for $25,000 each and $50,000 rare hydrothermal vent worm. Donors receive a framed photo of their namesake and a copy of the scientific paper that describes the species.

Goodhartz, the teacher from suburban San Diego, never bushwhacked through tropical rain forests or dived in perilous waters to hunt for undiscovered critters.

But he's headed for scientific immortality and understands there will always be people who disagree with his purchase.

"I haven't earned this like a scientist," he said. But he added, "If it helps Scripps, how can that be bad?"
