Research Interests
On the mudflats of Singapore, dwell many interesting intertidal
organisms like the mudskippers, sipunculids and the intertidal pulmonates. We
are intrigued by the capabilities of these organisms in surviving in such harsh
environment. These intertidal organisms
are exposed to low oxygen tension since they burrow into the mudflats. They are also exposed to the fluctuating
salinities and the high sulfide content in the mudflats. Thus, our laboratory has been actively
involved in elucidating the biochemical strategies employed by these organisms
in adapting to the harsh environment in the mudflats. Recently, we have been looking extensively on
the nitrogen metabolism of some interesting fish during terrestrial excursion
and high ammonia exposure. These include Misgurnus anguillicaudatus also
known as the weatherloach, Oxyeleotris marmoratus commonly known as Soon
Hock (a delicacy serve in our local restaurants), Channa asiatica (also
called the snakehead which is well known as a tonic used to speed recovery
after a surgery), Periophthalmodon schlosseri (a giant mudskipper found
in Pasir Ris Mangrove), Monopterus albus (swamp eel), Protopterus spp
(African lungfish) and Himantura signifer (freshwater stingray). Our results indicated that different fishes
used different strategies to prevent ammonia build-up in their tissues.
