Pulau Sekudu - New slugs!

Another day out with my fellow field enthusiast friends! This time, we visited a reef next to Chek Jawa... Pulau Sekudu, also affectionately called the "Frog Island" is frequently visited by fishermen with numerous abandoned fish and crab traps. With some concerted effort to monitor these drift netting areas, Ria and Zeehan have came up with a protocol to retrieve quantitative data on trapped fauna. So if you do see any drift nets anywhere, please do inform us via this website! :)

Back to the trip... Upon arrival, I spotted a big wild boar searching the grounds of CJ... So cool! I don't get to see many of our common mammals and I have heard so much from Siva's respective mammalogist students, from civet cats, leopard cats, otters and even rodents! Later, four little wild boars came out to join the feasting... Probably a family...


The team had much sightings and have shared their photos in the respective links:
Ria shares a Harlequin juvenile sweetlips, an uncommon Southerner in the North!
James shares his macro-shots on the nudibranchs sighted.
Kok Sheng and his usual ramblings on seastars...
Andy and his handy video cam, capturing the flourescence of the white-spiral fan worm!
Rene and Jerome shared their findings on their FB pages!

We shared a lot of our findings together... Just a breeze through... Kok Sheng found this pretty orange seahorse - Estuarine seahorse, Hippocampus kuda...


I spotted this tiny baby plain seastar, Astropecten indicus gliding on the substrate stealthily... :)


Other echinoderms include the Nepanthia sp. seastar, Biscuit seastar, Crown seastar and the orange sea cucumber...

There were a lot of hermit crabs and I found one that does not have a shell... It's naked! Wonder how it'll fend away the predators...


Sap-sucking slugs are in season! The Elysia ornata and another woolly-looking Elysia sp.


I chanced upon this hoof-shield limpet under a rock while we were photographing something else...


Other gastropods included the resident tiger moon snail, tiny trochus shell, noble volute laying eggs and wandering cowrie...


Look who's carrying the nem! This whelk snail appears to be an ideal 'host' for the nems to stick with on Sekudu... Some of the other snails are overwhelmed by the sheer size of nems!


Nem galore on Sekudu... An unusual looking swimming anemone (bottom right)... Parallel-striped swimming nem for now... :)



Again, I chanced upon these TINY slugs (<1cm) when I was looking at another slug... When I first saw these slugs, the name "strawberry slugs" came to mind! (I know, the colours are reversed but it does resemble the shape of a strawberry.) So from then on, it's known to us as 'strawberry slug', also named Costasiella sp.


Beautiful slugs next up! The Philinopsis lineolata... It's an uncommon slug that isn't nudibranchs but head-shield slugs... Not much I can find out about its diet... Similar to another species sighted on Lost Coast...


This little slug has a funny story to it... As I was leaving a specimen and hopping to find my next 'victim' for photographs, I stood up and spotted this purple dot (yes, it's 1cm)... So I just told James, "Hey, I see something there purple but maybe it's nothing...". Upon scrutiny, James said it WAS something and tada! Another uncommon nudibranch, Jorunna sp. Chay Hoon suggest that it may live on sponges and it has this sponge-like texture...


According to Chay Hoon, two new sightings of Cerberilla spp. on Sekudu... Whee!


What a day! I can't wait to head out to the shores soon... :D
