Trip to Normandy/Paris

Have always wanted to revive the blog with nature stuff but I guess I don't have the time for that.

Been busy with school and trainings and whatnots.

This trip to Normandy has definitely widened my vision, reignited my passion and refueled my determination. I think I can understand why people train so hard and fight so hard to be in the Top 8 or to be in the team, to go there to play against the stronger opponents. Those people there are really much different from those that we see in Singapore. I'm glad that I got the chance to be exposed and seen this at such an early (?) age.

Weather was cold but we fought hard. I think this is the first time we were so focused in polo. First time we felt like we are full-time/world-class athletes with little kids my height running to us for our signatures. Felt so cool and awesome. Watching the best players up close from all over the world congregating in a small town, displaying their skills and awing the spectators; small movements that can never be seen through videos; experience that can never be expressed in words. Makes me want to train harder, be a better player, and come back to meet these people again. But for now, I just want to improve my skills, my fitness and be a better player.

Paris was a nice place, but i guess it's not a place for me. There's nothing much to do other than shopping and eating. Never understood why branded goods are so appealing to people. I was wowed when I saw people/families spending money on those like as though they were buying groceries. Perhaps i'll only understand this a few years later. Disneyland was fun, but I concluded that I don't like to travel in big groups. And i concluded that museums and art works don't really appeal to me. Although the zoo and the aquarium were not as big/diverse as the others that i've seen, I still enjoyed it the most. The zoo was especially clean and spacious. The aquarium had a mixture of stuff that I didn't expect. And of course the great company that I had was awesome (:

Missing the time I had in Normandy, where I loved warming up in the cold weather, but hated going down into the freezing water. Playing polo in such cold temperatures were fun cos it makes me want to paddle faster and I don't feel the sore or fatigue in the water. BUT out of water it's another matter.

I don't regret spending so much time and money there. I hope that my tiny brain can capture and remember every single moment that I've experienced there and churn them into sources of motivation for the next few years of my life.

#backtoreality

For now, I need to catch up with school work and train harder.

Blog Revival

I haven't been blogging for the last 2-3 years but i've decided to revive this blog!

Many things happened in the last few years. Went for many field trips and worked at different places. Made many new friends and learnt a lot of new things! There are many things that I want to do now and one of it is to revive this blog! I shall try to blog at least once a month! :)

I'm currently a freshman in the BES programme in NUS! :) 2 weeks of school has passed. There were ups and downs but i'm definitely looking forward to the next 4 years in NUS.

I've lots of photos from previous field trips which I didnt blog about and I've been slacking off and didn't take photos for many of the field trips recently. But i think that photos are good records and will be useful (i hope) in the future so I shall have the discipline to bring my camera around in the future!

PS. I shall blog again SOON.

Basic Insect Identification from Insect Survey

Yay! I'm finally blogging. I realised i haven't been blogging for more than half a year. I was busy + lazy. Haha.

We went to Semakau to a land survey on insects and spiders some time ago last month. So after we caught those little creatures from the forest, Tammy and Ms Wang taught us how to ID the insects! (i was too lazy to take pictures so no pictures ): shall put in the pictures slowly when i take pictures of them next time :D)

And so, we started from the Orders that are commonly seen.

Order Orthoptera
- Have enlarged hind legs (those that can hop!)
- E.g. Grasshopper, cricket, katydid

Order Hemiptera 
- Front part of forewings hardened, back of forewings is membranous (Have a big 'X' on its back)
- Long, sucking mouth parts
- E.g. True bugs including hoppers

Order Coleoptera
- Entire forewing is hardened, folded over hindwing
- Hindwing hidden
- E.g. Lady bug

Order Blattaria
- Head is hidden under the pronotum
- E.g. Cockroach!

Order Lepidoptera
- Wings covered with scales
- E.g. Butterflies (club-shaped antenna) and Moths (Hairy/furry antenna)

Order Diptera
- 1 pair of wings
- Reduced hind wings for balancing called halteres
- E.g. Houseflies, Mosquitoes

Order Hymenoptera
- Membranous wings
- Narrow waist
- E.g. Bees, Wasps, Ants

Order Odonata
- Both pairs of wings are not coupled
- E.g. Dragonfly, Damselfly

Order Phasmida
- Resemble plant parts
- E.g. Stick insect, Leaf insect

Order Neuroptera
- Wings are net-like or nerve-like
- E.g. Lacewings

Hopefully i can remember them soooooooooooooooooon. Hehehehe.

Story of Liana


Lianas are woody climbers. They are often known as the 'highway' of the forest. The leaves of the liana are found near the top of the canopy to absorb as much sunlight as possible for photosynthesis. The liana then spreads along a few trees as it grows. This forms the 'highway' at the canopy of the forest, thus the animals like squirrels do not need to climb up and down the trees to get from one tree top to another. If one of the trees twined by the liana is to fall in the forest, it will bring down the other trees too. This allows the pioneer species to grow when there is a sudden gap in the canopy.

Story of Fig Tree and Fig Wasp


This is a White leaf fig (Ficus grossularioides).

Although fig trees are called 无花果 in chinese, (literally means no flower fruit), they do have flowers that are enclosed in the fig.

All figs have 4 prominent features.
1. Sap.
2. Prominent bud.
3. Triangular vein on the underside of the leaf.
4. Scars on the stem of the plant.

Fig trees have a symbiotic relationship with the fig wasps. Fig wasps are the only pollinators of the fig trees. The female fig wasp will drill its way through the fig, passing through the mouth of the fig which is covered with male flowers. Then, she will deposit her eggs in the cavity which is covered with female flowers. While depositing her eggs, she will also deposit some of the pollen that she was carrying. This helps to fertilize the flowers in the figs. However, as the hole is very small, the female wasp will usually lose its wings and die inside the fig after laying her eggs.

As the fig develops, the wasp eggs hatch and develop into larvae. After going through the pupal stage, the mature male will mate with a female, then it will dig its way out of the fig, creating a tunnel for the females to go through. The males usually sacrifice themselves and distract the preys around the figs to ensure that the females can continue the life cycle successfully.

Story of Macaranga

Haven't blog for a long time! Since exams are over and I promised someone that i'll blog, so here I am. Haha. I've been tasked to tell the 'story' of Macaranga... so here it is!

The Macaranga is also known as the Common Mahang, which has a symbiotic relationship with the ants. The ants will protect the plant by gnawing off any climbers that tries to climb onto the plant.

In return, the plant has stipules (black ring) that supplies the ants with food (lipids). It has hollow stems which serves as nesting place for ants, and also allow the ants to move freely inside the plant, and small holes on the stems to allow ants to move in and out of the plant.

Semakau Walk on 28 Aug

Haven't blog for a long time! Am quite busy with school etc. Hopefullyyyyy i'll get more time to blog about all the places that i went after this semester ends :D

Anyway, finally went to Semakau today again! :D But instead of guiding, i went as a participant with NUS High to listen to other people guide :D haha. My group was the Seagrass group! (: And our guide today was mindy!

As usual, as it was a morning walk, we had to walk to the intertidal area. The weather today was great! It was quite windy and cooling and i think everyone enjoyed the walk to the forest (:

The best reward from morning walks is the beautiful sunrise (:

Saw this plant beside the road along the rock barn. Never noticed it during the previous trips. Did it just grew recently? Or was i not observant enough? haha. Not sure what this plant is though.

We walked through a patch of secondary forest and reached the intertidal area. To get rid of the irritating mosquitoes, we headed out for the mangroves first.

Here's mindy telling the group about the mangroves! As these plants live under harsh conditions, they have several adaptations which enable them to survive better. For example, the Rhizophora species have prop roots which helps them to stabilize themselves on the soft ground. They also have waxy leaves to reduce water loss due to the high salinity level and the high amounts of sea spray that they get.

And of course, they have special adaptations for reproduction too. Instead of just letting their seeds germinate themselves in the harsh conditions, the seedlings, called propagules, are germinated on the parent tree. When it is more matured and ready to face the real challenge, it will drop down from the parent tree and get carried away by the current, and hopefully it will land somewhere suitable for growing.

When we look down at the mudflat, we often see trails created by these Creeper Snails. The longer the trails, the longer the tide has been out.

As we walked along the side of the forest, we saw this Sea Lime (Ximenia americana). Unfortunately, it wasn't flowering nor fruiting. During the one of the previous trips, i tried eating the fruits of the Mangrove Lime for the first time, and it tasted quite nice! :D

Next, we saw a Sea Hibuscus (Talipariti tiliaceus). This is also a coastal plant, with distinctive heart-shaped leaves. The yellow flower will open in the morning, and as the day gradually passes, the colour of the flower changes to pink, and then wither and dries up when the sun goes down.

On the same plant, there were quite a few juvenile Cotton Stainer Bugs (Dysdercus sp.). Interestingly, these Cotton Stainer Bugs feed on the seeds of this plant and are not able to survive on other plants.

As we headed out, we walked past another mangrove plant (Avicennia alba), which has pencil roots instead of prop roots like the Rhizophora species.

On the rocks, there were many Oysters (Family Ostreidae) growing.Oysters are sessile animals usually encrusted on rocky surfaces and filter feeds to get food from the surrounding water. During low tide, it will close up its shell to prevent water loss and protect itself from its predators.

Near the roots of a Bakau Tree, there were many Fiddler Crabs (Uca annulipes) scrambling around. The ones with a big claw are the male Fiddler Crabs. The big claw helps to attract the attention of the females and ''tells'' the females that 'LOOK! I have a big claw = I very powerful = I can protect you'. So, the bigger the claw, the sexier it is. However, it also handicaps the males as it cannot use the gigantic claw to feed itself and also makes itself more visible to the predators.

In the pools of water, we saw this Blue Striped Hermit Crab (Clibanarius longitarsus) in a telescopium shell! As hermit crabs are not true crabs, they have a soft abdomen which requires them to have extra protection. As the hermit crabs grow bigger, they will need to seek for a bigger shell to stay in. However, if it can't find a larger shell, instead of growing bigger, the hermit crab will shrink! :O Hence, it is important that we should not pick up shells whenever we visit the beach. Quoting Mindy, some people may have the mentality that it's okay to just bring home ONE shell because it is just ONE shell. Imagine everyone in Singapore has the same kind of mindset, then 4 million shells will be gone! And the poor hermit crabs will shrink, or have to walk around the shores naked.. ):

On almost every trip to Semakau, this is quite a common sight. Although this may look like some defecate of some sort of animals, it is actually an Acorn Worm (Family Enteropneusta) cast! The worm is buried underneath the sand, and as it moves deeper into the sand, it swallows the sand and process them, then passing the processed sand out from the other end of its body, to the surface thus forming the cast.

Here's a picture of the Victoria boys near the Seagrass meadow.

And our dearest Hunter-Seekers at work! (:

One of the girls in my group spotted this in one of the pools of water. I thought it was quite cool as it resembles a hand showing 4 fingers, which reminded me of the 4 points that all the guides will stress on before we go for an intertidal walk.
1. Always walk behind the guide as the guide will know which is the safest and best route to walk.
2. Always walk in a single file to minimize the damage done to the living things in the area.
3. Never touch things unless the guide says so, as there are many animals like the anemones with stinging tentacles and may sting quite badly when you touch them.
4. Never remove your shoes at any time during the walk as it is very dangerous to walk barefooted on the shores.

Back to the organisms, this was the first pair of Sand-sifting Sea Stars (Archaster typicus) in the pseudo-copulation position. It is said that these sea stars staying in this position for 3 months before they release their eggs and sperms into the surrounding water will help to increase the chance of external fertilization. It is great to see these sea stars reproducing! (:

As we walked on, we were greeted by a Sponge invasion. Sponges are very simple animals that comes in many different kinds of colours, shapes and sizes. Sponges in real life do not look like SpongeBob at all. In fact, i've never seen a square Sponge before! Hahaha.

The hunter seekers found us a Synaptid Sea Cucumber (Family Synaptidae). Sea Cucumbers have oral tentacles that they will extend to grab food particles into its mouth when it is submerged in water. As this species of Sea Cucumber has very thin walls, we should not touch them as they may be stressed up and disintegrate!

At the same area, we saw not one, but TWO! Dragonfish Sea Cucumber (Stichopus horrens). Unlike us, Sea Cucumbers are invertebrates, thus, when they are out of water, it may look like it's 'melted'. This also enables them to camouflage better in its surroundings.

Then, we headed for the Death Zone! If you look closely, you'll see a walking trail amongst the Seagrass. The Death Zone was formed after numerous trips. To minimize the damage done to the Seagrass meadow, we will always stick to one path, thus stressing the importance of walking in a single file.

At the side of the trail, i saw this very beautiful Stonefish Sea Cucumber (Actinopyga lecanora).

When we reached the sandy area, we saw this Cushion Star (Culcita novaeguineae). Just like other Echinoderms, including sea cucumbers, they have a penta-radial symmetry which can be seen clearly with the 5 rows of tube feet.

We also saw this Sandfish Sea Cucumber (Holothuria scabra). This is the species that we usually eat in the Chinese restaurants. However, it needs to be properly processed before it is edible.

Amongst the Seagrass, we saw this Gigantic Anemone (Stichodactyla gigantea). This is one animal that we shouldn't touch as these anemones have stinging cells in their tentacles that may sting your fingers if you touch them.

As we moved on, we saw this ultra long drift net just beside the seagrass. It feels very depressing to see drift nets on our shores as it causes detrimental effects to the animals like fishes and crabs. 

Many fishes were found trapped and dead in these nets..

The possession of these drift nets is actually illegal in Singapore. Despite many drift nets found and many innocent animals killed, the authorities don't seem to be doing anything about it. Hopefully the drift nets will be removed soon so that animals will not be killed by it anymore.

Moving on, we saw two Noble Volutes (Cymbiola nobilis).  Although they have very pretty shells, they are actually very fierce predators that can wrap their muscular foot around their preys to suffocate them!

Beside the Noble Volutes, we saw this Sand Collar. It is the eggs of the Moon Snails. When the eggs hatch into little Moon Snails, the Sand Collar disintegrates and disappears. Signs of reproduction tells us that the animals are doing well! (:

This looks like a.. hybrid? Haha it doesn't look like the normal Knobbly Sea Stars that we usually see.

The Knobbly Sea Stars (Protoreaster nodosus) are the iconic animals of Semakau. On every visit, I'll hope to see some of the knobblies to make my day. Just learnt from a shrimp expert that some tiny tiny shrimps may live on the knobblies! Shall try to look out for them next time.

We also saw a dead Scallop (Comptopallium radula). The Scallop has a special way of moving which i think is quite cute :D As they are bivalves, they have a two-part shell and to move, they will flap their shells and eject water from their mantle cavity.

As we moved further out, we saw another Stonefish Sea Cucumber (Actinopyga lecanora)..

and 2 more Cushion Stars (Culcita novaeguineae)! Happy to see the yellow one again :D it seems to be doing well and growing bigger everytime we see it! (:

It seems to be a Echinoderms day as we saw 4 different kinds of Sea Cucumbers and 3 different kinds of Sea Stars! (: A group shot of the juniors with our awesome guide :D Hope everyone enjoyed themselves today, and jiayou to the juniors who are supposed to complete their assignment! :P
