The oceans are home to some of the world’s most brilliant brains.
Irrawaddy dolphins were discovered for the first time in 2012 in West Kalimantan, a region of Indonesian Borneo famed for its diverse biodiversity and lush tropical forests.
The uncommon dolphins, also known as orcaella brevirostris, were discovered during a WWF-Indonesia and the Regional Office for Marine, Coastal, and Resources Management Pontianak investigation (BPSPL).
“Because the existence of Irrawaddy dolphins in West Kalimantan seas was previously unknown, we are delighted by the findings of this exploratory research and believe that it will help us learn more about their population and range.”
WWF-Indonesia Conservation Biologist Albertus Tjiu is one of the study’s key scientists.
The crew also came across a pod of Humpback dolphins, demonstrating how diverse the Kalimantan seas are in terms of wildlife.
“The findings of this study highlight the need of safeguarding dolphin habitat from the source of rivers in Borneo’s heart.”
“To the island’s lower rivers, including the Batu Ampar mangroves and nypah forests, the narrow straits, and the Kubu Raya coastal regions, West Kalimantan.”
There are around 6,000 Irrawaddy dolphins in the world, the bulk of which live in Bangladesh’s coastal waters.
The remaining population is dispersed over Southeast Asia, including Thailand, Cambodia, Indonesia, the Philippines, and Australia’s northeastern coast.
The IUCN lists Irrawaddy dolphins as vulnerable, while the species is classed as severely endangered in several locations, including the Mekong River, the Ayeyawardi River, and the Mahakam River in East Kalimantan.
