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. As it turned out, adults were excited too! My wildlife research students all have names too: civetgirl, ottergirl, otterboy, monkeygirl, pigboy, palmboy. Their effort is exported into scientific input into wildlife mamagement and stakeholder feedback to developments.

I enjoy writing and have been 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 have written less and less. Initially in student newsletters in the 80’s and 90’s and then publicly from 1998 with mailing lists. In 2003, I 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 then in the 2010’s, I tried Instagram and LinkedIn.

  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
