Phthalate acid esters (PAEs) are widely used plastic additives that have become ubiquitous contaminants in marine environments. Filter-feeding baleen whales may be exposed to these pollutants through water, prey or ingested plastic debris. While macroplastics have been reported in the gut of a southern right whale (SRW, Eubalaena australis ), exposure to PAEs has not been assessed. Here, we quantified three lipophilic PAEs, di...

Milk production strategies, duration, and composition vary among mammals. Odontocete cetaceans exhibit a long lactation strategy characterized by high parental investment and prolonged nutritional dependence. Understanding the nutritional demands of these offspring during lactation is complex, particularly due to their aquatic lifestyle. This study examines the nutritional dynamics of endangered Franciscana dolphins ( Pontopor...
