A Crab-ulous day out at Chek Jawa!

We are delighted to have had 42 visitors join today at Chek Jawa for our monthly walk on the 25th of November!

Before we headed off to Pulau Ubin, Ria spotted a family group of otters at Changi Creek! They were very shy around humans and hugged the seawall as they swam past the jetty.

At Chek Jawa, everyone gathered outside the start of the trail for a quick group photo right before we set off. Here are the happy visitors posing for the photo!

It was a beautiful sunny day, which made the scenery atop the Jejawi Tower even more breathtaking!

Visitors could enjoy panoramic views of Chek Jawa and could even see the high tide from the tower. Here's an amazing photo of the visitors enjoying the sights by one of the participants of the walk, Glenda Heng!

One of the groups even stopped to take a photo with the beautiful backdrop of the sky!

Back in the mangrove, the visitors were entranced by the Nipah Palm, a plant found in the mangrove which provides us with our favorite attap chee! The seeds of the Nipah Palm were quite close to the boardwalk, so visitors were able to take a good picture of them.

Eagle-eyed visitors also spotted fiddler crabs in our mangroves! The male fiddler crabs have an enlarged claw that is of a very bright color which they use to attract mates and intimidate other males.

Here's a beautiful picture of a male fiddler crab taken by Glenda.

Along the walk, we also spotted a giant mudskipper resting in a pool as well as a crimson sunbird hovering above us! Glenda also spotted a Centaur Oakblue and Common Bluebottle, which are both beautiful butterflies.

Near the coast, visitors also spotted a lot more fiddler crabs that were very actively waving their claws at each other! Take a look at them in the video below.


It was high tide today, so the Gold-spotted mudskippers had all come further up shore. The visitors were able to see them up close in their huge numbers!

One group had also spotted two water monitor lizards sunbathing on the shore! Indeed, the sun had been quite hot out on the boardwalk and it did make for very nice pictures. Once again, Glenda Heng had captured very nice shots of the visitors on the coastal boardwalk!

On our way back through the coastal forest, we also saw cotton stainer bugs on a sea hibiscus tree! These bugs feed on the sea hibiscus seeds and sometimes will congregate in large groups on a single leaf as shown below.

After the walk, the children sat down and drew what they saw on the walk! Here are some of the children with their lovely drawings.

One of the children even took it upon himself to make some octopus! He was very creative to use the fallen leaves of a tree nearby to form legs. Here he is with his creation!

We had a very enjoyable walk today with all the lovely visitors. Thank you to all the visitors for coming down to explore Chek Jawa with us! A big thank you to Glenda Heng for sharing with us her photos and giving us permission to use them as well! And off course, thank you to Ley Kun, Ria and Dayna for guiding today as well.

Our next walk will be on the 16th of December 2017 (Saturday) at Chek Jawa. You can register here. Hope to see you there!

Here there be serpents: Pasir Ris Mangroves

We were very happy to welcome about 70 visitors for our latest walk! Many had never been to the mangroves of Pasir Ris Park, which are in fact the most easily accessible of our remaining mangrove forests. Thanks to the eagle-eyed spotting of one of our guides, they got to see the elusive Shore Pit Viper (Cryptelytrops purpureomaculatus) on their very first visit! The Shore Pit Viper is an ambush predator, sitting camouflaged in one spot for days at a time for prey to pass by before striking with lightning speed. It's deadly venom quickly immobilises small animals like rodents, birds, and lizards. Although it is dangerous if provoked, it was perched safely far away from the boardwalk so our visitors could observe it with no worries.

There were also many Giant Mudskippers (Periophtalmodon schlosseri) about, guarding the "swimming pools" they dig for themselves to rest in at low tide. This provides them with a steady source of oxygen as well as a burrow which they can hide in if a predator appears.

A small nest of honeybees was also present in the mangroves. These insects are important pollinators for many plants in the mangroves and will not attack unless first provoked.

Many different species of snail live amongst the mud. One such snail is the Belongkeng (Ellobium scheepmakeri), also known as the Mangrove Land Snail, which feeds on algae. This is now critically endangered in Singapore due to habitat loss and past overcollection for food.

No walk in Pasir Ris would be complete without a sighting of a Malayan Water Monitor Lizard (Varanus salvator)! There were many of them spotted on our walk clinging onto tree branches as they prepared to turn in for the night. Often misidentified as their close relatives the Komodo Dragons, they feed mainly on carrion and small animals and pose no danger to humans if left alone. In other countries where they are hunted, they can be hard to spot, but here in Singapore we are blessed to be able to see them up close!

If you couldn't make it for our walk this time, fear not! Keep a look out for our next walk coming in October, like our Facebook page at https://www.facebook.com/Naked-Hermit-Crabs-1825391097477979/ and share about us with you friends! We hope to see you soon!
At the end of the walk, the kids draw what they've seen!

The one-week school break in September is coming up, and the Naked Hermit Crabs are specially organising a very special nature walk at Pasir Ris Mangroves for young families on 3 September, Sunday. This is a FREE nature walk on the mangrove boardwalk at Pasir Ris Park.

Sign up now on our online registration form! Don't miss the opportunity to see some wildlife in action! Pasir Ris Mangroves is conveniently located 10 minutes away from Pasir Ris MRT station. We only do Pasir Ris Mangroves a couple of times in a year, so don't miss this opportunity!



There are many creatures look out for in the mangroves, such as mudskippers, tree-climbing crabs, snails, herons and monitor lizards. The best part of the nature walk is at the end when we get to the small jetty over the river. There is a lot of animal activity in the evenings. We have seen young monitor lizards crawling into their nests as they settle in before nightfall.  Sometimes, you may even spot kingfishers, jellyfishes and water snakes! It really is quite exciting for the children to be able to see these animals in the wild.

Date: 3 September, 2017 (Sunday)
Time: 5 pm (We should end around 6.30pm, just before sunset.)
Meeting point: Pasir Ris Park, Carpark C.
