Alobi Foundation memfasilitasi proses nekropsi seekor pesut laut betina (Orcaella brevirostris) pada Sabtu, 8 November 2025 di PPS Alobi Babel Kampoeng Reklamasi Timah air jangkang.
Pesut tersebut ditemukan dalam kondisi mati pada malam sebelumnya oleh nelayan yang sedang mencari ikan di Pantai Kuala, Kecamatan Air Anyir, Kabupaten Bangka, di dekat Jembatan Emas Bangka Belitung sekitar pukul 18.30 WIB. Jasad pesut tersebut kemudian dibawa ke salah satu rumah warga di Kelurahan Pasir Garam, Kecamatan Pangkalbalam, Kota Pangkalpinang.
Setelah mendapatkan laporan warga, tim Alobi dan Balai Konservasi Sumber Daya Alam (BKSDA) Sumatera Selatan berangkat menjemput jasad pesut tersebut untuk dinekropsi di Pusat Penyelamatan Satwa (PPS) Alobi Foundation Air Jangkang. Ketika diambil, jasad pesut sudah berbau menyengat dan dikerubungi lalat.
Proses nekropsi dilakukan oleh drh. Magri Nora Diantara dan drh. Yayan Muchlus Marchito dari Asosiasi IAM Flying Vet dan Balai Karantina Kepulauan Bangka Belitung.
Proses nekropsi mencatat bahwa panjang pesut tersebut adalah 2,25 meter dari moncong ke pangkal ekor. Lingkar tubuh maksimumnya sebesar 1,02 meter. Lambungnya teridentifikasi dalam keadaan kosong, mengindikasikan bahwa pesut sudah tidak makan dalam waktu lama. Selain itu, paru-parunya menunjukkan warna gelap yang tidak merata.
Dari temuan ini, dokter hewan menduga bahwa salah satu faktor yang kemungkinan berkontribusi terhadap kematian pesut tersebut adalah kelaparan. Terdapat juga indikasi adanya gejala keracunan pada paru-paru pesut. Saat ini, sampel bagian tubuh pesut sedang dalam proses pengecekan di laboratorium untuk memberikan informasi lebih rinci mengenai indikasi keracunan tersebut. Setelah melalui proses nekropsi, jasad pesut laut serta seluruh bagian tubuhnya langsung dikubur di sekitar fasilitas PPS Alobi Foundation Air Jangkang.
Perlu diketahui, pesut atau Irrawaddy dolphin adalah spesies mamalia laut euryhaline. Ini berarti, pesut dapat hidup di air asin maupun air tawar. Pesut yang dinekropsi kemungkinan merupakan populasi yang tinggal di air asin. Pesut juga merupakan satwa yang dilindungi di Indonesia. International Union for Conservation of Nature (IUCN) mencatat pesut sebagai spesies genting (endangered). Faktor utama yang mengancam pesut adalah aktivitas industrial di sekitar sungai dan pesisir, khususnya industri perikanan.

Alobi Foundation facilitated the necropsy process of a female Irrawaddy dolphin (Orcaella brevirostris) on Saturday, November 8, 2025.
The dolphin was found dead by fishermen off Kuala Beach, Air Anyir District, Bangka Regency, near the Bangka Belitung Golden Bridge in the previous evening at around 6:30 p.m. local time. The dolphin’s carcass was then brought to a resident’s house in Pasir Garam Subdistrict, Pangkalbalam District, Pangkalpinang City.
After receiving reports of the dead dolphin, the Alobi team and the Natural Resources Conservation Agency (BKSDA) of West Sumatra departed to retrieve the carcass for necropsy at the Alobi Foundation’s Air Jangkang Wildlife Rescue Center (PPS). When retrieved, the carcass had already begun to emit a strong odor and was surrounded by flies.
The necropsy was carried out by veterinarians Magri Nora Diantara and Yayan Muchlus Marchito from the Indonesian Aquatic Megafauna (IAM) Flying Vet Association and the Bangka Belitung Islands Quarantine Agency.
The necropsy revealed that the dolphin measured 2.25 meters in length from snout to tail base, with a maximum body girth of 1.02 meters. The stomach was found to be empty, indicating that the dolphin had not eaten for a long period of time. In addition, the lungs exhibited uneven dark coloration.
Based on these findings, the veterinarians suspected that one of the possible contributing factors to the dolphin’s death was starvation. There were also indications of poisoning symptoms in the lungs. Tissue samples from the dolphin are currently being analyzed in a laboratory to provide more detailed information regarding the suspected poisoning. After the necropsy, the dolphin’s body and all its parts were immediately buried near the Alobi Foundation’s PPS Air Jangkang.
It is important to note that the Irrawaddy dolphin is an euryhaline marine mammal species, meaning it can live in both saltwater and freshwater environments. The dolphin examined in this case was likely from a saltwater population. Irrawaddy dolphins are a protected species in Indonesia. The International Union for Conservation of Nature (IUCN) lists the species as endangered. The main threats to Irrawaddy dolphins include industrial activities around rivers and coastal areas, particularly those related to the fishing industry.
