The Flying Saucer At Sunset

Lenticular clouds (Altocumulus lenticularis) are stationary lens-shaped clouds with a smooth layered appearance that form in the troposphere, usually above mountain ranges. One was spotted in Singapore recently...

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...

A Kaleidoscope Of Colours, Shapes And Patterns

Spectacular and innovative in design, the Flower Dome replicates the cool-dry climate of Mediterranean regions like South Africa, California and parts of Spain and Italy. Home to a collection of plants from deserts all over the world, it showcases the adaptations of plants to arid environments...

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?

The Deep Sea Mystery Circle - A Love Story

(Source : Inhabitat)
Introduced to life under the sea in high school through snorkeling, Yoji Ookata obtained his scuba license at the age of 21. At the same time, he went out and bought a brand new Nikonos, a 35mm film camera specifically designed for underwater photography. He devoted all his spare time - aside from his day job - to perfecting his art of underwater photography. Then, at age 39, he finally made the transition. He quit his office job and became a freelance underwater photographer.

But even for a man who spent the last 50 years immersed in the underwater world of sea life, the ocean proved infinitely mysterious. While diving in the semi-tropical region of Amami Oshima, roughly 80 feet below sea level, Ookata spotted something he had never seen. And as it turned out, no one else had seen it before either.

On the seabed a geometric, circular structure measuring roughly 6.5 feet in diameter had been precisely carved from sand. It consisted of multiple ridges, symmetrically jutting out from the center, and appeared to be the work of an underwater artist, carefully working with tools. For its resemblance to crop circles, Ookata dubbed his new finding a “mystery circle,” and enlisted some colleagues at NHK to help him investigate.

In a television episode that aired last week titled “The Discovery of a Century: Deep Sea Mystery Circle”, the television crew revealed their findings and the unknown artist was unmasked.

Underwater cameras showed that the artist was a small puffer fish who, using only his flapping fin, tirelessly worked day and night to carve the circular ridges. The unlikely artist - best known in Japan as a delicacy, albeit a potentially poisonous one - even takes small shells, cracks them, and lines the inner grooves of his sculpture as if decorating his piece.

Further observation revealed that this “mysterious circle” was not just there to make the ocean floor look pretty. Attracted by the grooves and ridges, female puffer fish would find their way along the dark seabed to the male puffer fish where they would mate and lay eggs in the center of the circle. In fact, the scientists observed that the more ridges the circle contained, the more likely it was that the female would mate with the male. The little sea shells weren’t just in vain either. The observers believe that they serve as vital nutrients to the eggs as they hatch, and to the newborns.

What was fascinating was that the fish’s sculpture played another role. Through experiments back at their lab, the scientists showed that the grooves and ridges of the sculpture helped neutralize currents, protecting the eggs from being tossed around and potentially exposing them to predators. It was a true story of love, craftsmanship and the desire to pass on descendants.

Why You Should Not Visit The Marine Life Park At RWS

Sentosa
South, Singapore
May 2013

(This article is part of Merlion Wayfarer's series on Animal Welfare.)

Merlion Wayfarer was at Sentosa when she spotted the dolphins at the RWS Marine Life Park. 

These two pictures taken were of different pools. Both pools had floors stained with algae growth. For each pool, there were several dolphins crammed into a space not much bigger than a volleyball court. In the second photo, two of the dolphins were beached, while another was knocking its head on the wall of the pool. 

(Photos taken at sunset)

It was very heartrending to see them. 

Please do not visit the Marine Life Park at RWS.

Tampines Eco Green - Among Green Grass

Tampines Eco Green
East, Singapore
May 2013

Tampines Eco Green is a haven for biodiversity, with a multitude of natural habitats - open grasslands, freshwater wetlands and secondary rainforest. Naturally, among green grass, finds abound.

Contained within the nutrient-rich ponds, water snails thrive...

Clutches of bright pink apple snail eggs can be seen...

 Moths (Heterocera), Butts (Rhopalocera) and Dragons (Anisoptera) lay at rest...

 There were also some weird finds, including a 5-legged transparent grasshopper (Caelifera)...

Mud Facials & Oil Baths For The Skippers

Pasir Ris Park
East, Singapore
March 2013

Merlion Wayfarer was at the mangroves at Pasir Ris Park one afternoon. Being mid-tide, this was the trip when she saw the most number of mudskippers!
  • Skippers swimming to stay slim...

  • Skippers having a mud facial...

  • Skippers hiding in the shade for fear that they will grow more spots...

  • Skippers paddling to learn how to swim like a fish...

   
  • Skippers having an oil bath...

    
  • Skippers learning how to breathe underwater...

    

Arachnida (Spiders)

 
Jumpers are always very curious little ones. Here is a Ligurra Latidens (Mangrove Jumper) Female staring right into the lens...


See how hard the armour protecting her head is...

She can be quite aggressive when she sees a prey that she sees something she doesn't quite like...


The Rest


There was a lot of water today. Due to the inflow, new streams are etched into the mud. This mini-waterfall, nearly one metre in height was created due to a sinking in of a mudflat. The height of the water created a significant amount of foam in the pool below.


Quite a few kingfishers can be heard near the entrance closer to the carpark. Here's a Todiramphus Chloris (Collared Kingfisher) that stands out easily:

A katydid, an elegant grasshopper and a moult...


A couple of mating houseflies and a Agrionoptera Insignis (Grenadier) dragon...


A collection of bugs...
