Mr. Rooswiadji from WWF Indonesia sent me a photo by Surasak Thongsukdee from WWF Thailand last Monday. Thanks to him, now I know how big Irawaddy dolphin’s melon is!
And yes, what’s on photo above is one of the most sensational freshwater animals (not ‘marine’, like other species of whales) in South East Asia, the Orcaella brevirostris or also called Irawaddy dolphin. It’s distributed mainly in freshwaters, like estuaries and rivers, and some of them even help fishermen in Balikpapan, Samarinda, and other freshwater regions in Kalimantan (Borneo). They’re listen as ‘Vulnerable’ in IUCN Red List, meaning their population number could decline if humans pay no attention to their existence. They’re mainly threatened by the possibility of by-catch (it’s a marine term, meaning ‘caught unintentionally by fishermen while collecting fishes from nets they use’).
PS: This is a queued post I wrote on Monday since I’d already be at Pari Island at Thousand Islands right now. Me and other Biology students Batch 2009 are staying for two nights, starts from today, here for a Animal Behaviour field lecture. Have a good Thursday, Guys!
