flourescing white spiral fan worm @ sekudu - Oct2011

There were quite a few of these white spiral fan worms on the Sekudu shore. The spiral arms are in themselves a wonder to behold as they unfurl from their protective tube. The magic comes when the unfurled arms are lit with black light (from a low powered UV LED torch). The arms take on an eerie bluish glow.

Surprisingly, other non-white fan worms do not exhibit similar fluorescence. What function does it serve? If at all any function at all? Or is it so that white colours simply reflect the UV light back out (much like white paper does)?

shoreboars @ chek jawa - Oct 2011

A short clip showing that the wildboars at Ubin do enjoy the Chek Jawa shore just as much as its resident and visiting shorebirds. The first part shows a lone large male boar merrily digging deep for food at the northern shore and the second part shows some females with juveniles foraging at the central shore to the right of the House #1 pier.

fishhooked boar @ chek Jawa 16Oct2011


She was fine in the early morning but by the late morning, there was a metal fish hook and line stuck just inside her mouth on the left side.

Pity this had to happen to one of the tamest wild boars at Chek Jawa. This particular boar would greet visitors at the Chek Jawa visitor centre all throughout the day.

Apparently there had been some fishermen at fishing illegally at CJ South overnight and perhaps they had carelessly left some bait on a discarded hook and line. Or the hook and line may have been left some time ago by other fishermen.

She was foraging for food in the bush and near the bicycle park where some visitors had thrown human food items (like yoghurt drinks) at the macaques and the boar. Some of the monkeys had come down from the trees and taken water bottles from the parked bicycle baskets. The sound of plastic being crunched by sharp teeth higher up in the trees seemed to be a standard sound shortly after new visitors rode in and parked their bikes with partially consumed food and drink items left in the bicycle baskets. I hope these monkeys do not get accustomed to a high refined sugar diet.

The hooked boar occasionally stepped on the trailing line and this caused her some discomfort because that would exert a sudden pull on the hook attached to her mouth. I hope the wound does not get infected over time especially given that boars usually forage with their snouts in the topsoil to find food.

Attempts to get close to the boar proved futile as she moved away each time her comfort zone was breached. Hope she receives aid soon enough.


UPDATE 17thOctober2011 : one of the resident Ubin Taxi 'uncles' had managed to remove the hook on the afternoon of the 17th. Apparently, feeding the boar chewy bread did magic as the hook dislodged itself during the chewing. Great job! And thanks to NParks and ACRES for getting ready to assist in the interim. Good to know help was available.

siamese peninsula pit viper @ langkawi

Came across this snake at about 9am on the grassy road shoulder at about 600m (near the roadside waterfall) up Gunung Raya on Langkawi Island. It seemed to be trying to get some sun to warm up as the clouds had moved in earlier.

I had been distracted by the many pieces of flourescent green grass cutter plastic which had been thrown away along the roadside (and at many other locations all around the island where grass cutting is done) and was about to take a few steps forward when the distinctive coils of a green snake jumped out from the grassy verge and I stopped immediately. It was the same colour of the grass around it. A quick look at the triangular head of the snake showed it to be that typical of a pit viper. It did not move much at all and did not seem at all bothered with the attention it got after I motioned for the rest of the group to walk over from their birding stop.

It was indeed surprising to see this viper on the grass verge away from any vegetation as one would normally expect pit vipers to seek refuge on shrubs.The mountain top had been covered in mist and the cool moist air must have caused the viper to seek warmth from the morning sun which occasionally peeked through the cloud mist.

Estimated length : between 40 to 50 cm.
