Eyes Of 30,000 Honeycombs

With 30,000 individual facets, dragonflies have the most number of facets among insects. Each facet, or ommatidia, creates its own image, and the dragonfly brain has eight pairs of descending visual neurons to compile those thousands of images into one picture...

Lightning Strikes, Not Once, But Many Times

Unlike light, lightning does not travel in a straight line. Instead, it has many branches. These other branches flashed at the same time as the main strike. The branches are actually the step leaders that were connected to the leader that made it to its target...

Are You My Dinner Tonight?

A T-Rex has 24-26 teeth on its upper jaw and 24 more on its lower jaw. Juveniles have small, sharp blade-shaped teeth to cut flesh, whereas adults have huge, blunt, rounded teeth for crushing bones. Is the T-Rex a bone-crushing scavenger?

Pasir Ris Park - Decreasing Biodiversity Sightings

Pasir Ris Park
East, Singapore
June 2014

It's been some time since Merlion Wayfarer been to the Pasir Ris mangrove swamps. And it has been disappointing how the biodiversity sightings there decreases over the past few years.

|   March 2010   |   January 2013   |   July 2013   |

A male Epeus flavobilineatus (Yellow-Lined Epeus) spider, a bug, an ant, a wriggling caterpillar, and an Ardea cinerea (Grey Heron) were spotted in the 1.5 hour walk...

The decreased variety and number of sightings could be attributed to several factors:
  • Impending bad weather, e.g. rain
  • Water Pollution
    Fecal matter has been detected in the sea near the mangroves. At times, "No swimming" signs have been put up. (See "Thrown Away By The Kelongs")
  • Oil Spills
    (The sand in Pasir Ris often has oil stains among its deeper layers. Sometimes, oil streaks can be seen in the mangrove puddles.)
  • Increased number of visitors
Merlion Wayfarer hopes the biodiversity of the area can be restored very soon.
 

Sungei Buloh - The Dark Dangerous Branch

Sungei Buloh Wetland Reserve
North, Singapore
December 2013

A species of mangroves and coastal forests, the Cryptelytrops purpureomaculatus (Shore Pit Viper) has a reputation for being unpredictable and should be approached with caution. Giving no warning signs, this snake will strike readily and far at any threat, and its powerful haemotoxic venom can cause serious illness or even kill. 

This shy snake looks just like another branch in a mangrove tree where it usually coils motionless. A small snake with the typical broad triangular head of a viper, it has large red eyes on a rather angry looking face. It is more active at night.  By day it can be found resting on low branches one or two metres from the ground.


Its colour can vary from a uniform dark grey or purplish-brown to a weakly-patterned brown, with a white stripe along each flank, or even greenish-yellow with dark mottling. The scales are strongly keeled (i.e. ridged). Males grow to a total length of 66.5 centimetres (26.2 inches), females 90 centimetres (35 inches). The maximum tail lengths are then 12.5 centimetres (4.9 inches) and 14 centimetres (5.5 inches) respectively.


Feeding on lizards, frogs and other small animals, possibly small birds, similar to other vipers, it has heat-sensing pits on its lips to detect its prey.

Sentosa - A Billed Visitor

Sentosa
South, Singapore
March 2014

It was a normal hot weekend afternoon at Sentosa when Merlion Wayfarer was startled by a familiar but very unexpected cry from the trees. Looking among the trees above the KFC outlet at Imbiah Station, she spotted this very surprising sight - An Anthracoceros albirostris (Oriental Pied Hornbill) in the urban jungle next to the Resorts World Sentosa!


The Oriental Pied Hornbill disappeared from Singapore in the mid-1800s, possibly due to hunting and loss of suitable habitat. In 1994, a pair was recorded from Pulau Ubin. Once thought to be extinct in Singapore, the bird is re-establishing healthy colonies here, due in large to the collective efforts of the National Parks Board (NParks), Jurong Bird Park, and Singapore Avian Conservation Project (SACP). 

Good to see you enjoying the resorts here in Sentosa, Billed Visitor!

Sengkang Park - That Thing With The Wayang Feelers

Sengkang Park

Sengkang Riverside Park is located at Anchorvale Street and is situated alongside Sungei Punggol. The park is home to a unique water feature, a constructed wetland that collects and filters rainwater naturally through its aquatic plants. Despite its man-made features, the park contains a variety of fauna among its aquatic and terrestrial plants.
