Hello, thanks for stopping by.

Otterman by Meryl ThengI am N. Sivasothi a.k.a. Otterman, an educator who loves animals, nature and the environment. I enjoy cycling, using the macintosh and exploring the internet.

I gave myself the moniker Otterman when I started research about otters in the early 90’s, to excite kids at talks and introduce an then unfamiliar animal to Singaporeans, and as it turned out, adults were excited too! My wildlife research students all have names too: civetgirl, ottergirl, otterboy, monkeygirl, pigboy, palmboy, etc.

I am fascinated by how a blog can be a personal notice board to the world. I am able to communicate, remember, highlight, enthuse and spread some cheer.

I’ve been writing publicly since 1998 with mailing lists, and in 2003 finally began a personal blog which moved to this WordPress site in 2007. For specific themes, I have a few other blogs on various platforms.

With time, I struggle to write or find time to mention the memorable things. So twitter has helped out since 2007. Then came Facebook, which the Swedes on the Götheborg introduced me to in 2006. And LinkedIn, but rarely from 2019.

For ‘About the speaker’ – N. Sivasothi, a.k.a. ‘Otterman’ has been immersed in mangroves and wildlife for research, education and conservation at the National University of Singapore since the late 1980’s. He earned the moniker ‘Otterman’ through his work with otters in the 90’s and promotes youth development, public education and environmental stewardship. He coordinates NUS Toddycats, the International Coastal Cleanup Singapore, OtterWatch, as well as The Biodiversity Roundtable and The Biodiversity Friends Forum in partnership with NParks.

He contributes his expertise actively in numerous wildlife conservation working groups, ground-up partnerships and close-door engagements to mitigate development impact, which seems endless! He is happiest now as an active proponent of habitat enhancement and community involvement through the One Million Trees movement in Singapore. 

About Me: I list a feature about my environmental work from 2011 and several older blog posts penned by my naturalist-on-a-mission kaki Ria Tan and my blogging trinity friends; all are obviously kind accounts and a heart-warming read when I need encouragement. More recently, a couple of articles focus on exploits in tertiary education. Below those are two interviews by fellow mac addicts, part of a community who have helped each other and encourage each others interests.

  1. Mr Otterman, Hello. I,m coming to Singapore to work for a few months. I’m a devoted bicycle commuter and long time associate of Critical Mass and the Midnight Ridazz here in Los Angeles. Can you tell me how I might be able to get connected to the cycling community in Singapore? Thank you, sincerely, Eric Gill

  2. Wee hah… I always remember the story you told me of how you connected the macs at the community centre in Serangoon when you were in school
