Authors Summary
The Indian Ocean Cetacean Network (IndoCet) focuses on cetacean research and conservation in the south-western Indian Ocean (SWIO). The network maintains a website, as well as a newsletter and social media pages. The website includes a regional literature repository, a ?metadata? page (telemetry, photo-ID, biopsy, acoustics) and a ?Report a Stranding? page that standardizes/centralizes SWIO strandings data and provides guidance on species identification and stranding response. Whale disentanglement workshops in partnership with the IWC were held in Reunion and Mayotte (June 2023) and a refresher workshop was held in Kenya (March 2024). A new initiative called the "Network of Marine Mammal Observers" (NeMMO) aims to increase the quality, quantity, and availability of cetacean data in the SWIO through MMO?s working onboard platforms of opportunity. Data are stored in a GIS database on the Sextant/SIMM-OI portal and currently includes 1,139 cetacean sightings of 24 different species. IndoCet members have worked with HappyWhale to upload/match SWIO humpback whale photo-identification data. The aim is to produce estimates of abundance and between-region exchanges for the next IWC in-depth assessment. Other ongoing initiatives include the COMBAVA project which assesses humpback whale song structure and temporal distribution in the SWIO, the QWIO project (Quieter Western Indian Ocean), an assessment of threats to marine megafauna associated with shipping (underwater radiated noise, ship strikes) and the Indian Ocean Humpback Dolphin Conservation Network (HuDoNet), a consortium focused on Sousa plumbea. SWIO humpback whale telemetry datasets have been collated on the IndoCet website (Fossette et al., 2014; Cerchio et al., 2016; Dulau et al., 2017) to which more recent tagging data will be added; Reunion in 2019-2022 and Tanzania in 2023.

Abstract
The changes are very minor. We added another co-author, corrected an issue with several co-author affiliations and added a single missing reference.
