AB  - Due to their high trophic position and long life span, small cetaceans are 
      considered as suitable bioindicators to monitor the presence of contaminants in 
      marine ecosystems. Here, we document the contamination with persistent organic 
      pollutants (POPs) and total mercury (T-Hg) of spinner (Stenella longirostris, n 
      =21) and Indo-Pacific bottlenose dolphins (Tursiops aduncus, n=32) sampled from 
      the coastal waters of La Reunion (south-western Indian Ocean). In addition, seven 
      co-occurring teleost fish species were sampled and analyzed as well. Blubber 
      samples from living dolphins and muscle from teleosts were analyzed for 
      polychlorinated biphenyls (PCBs), DDT and metabolites (DDTs), chlordanes (CHLs), 
      hexachlorocyclohexanes (HCHs), hexachlorobenzene (HCB), and polybrominated 
      diphenyl ethers (PBDEs). Methoxylated PBDEs (MeO-PBDEs), reported as having a 
      natural origin, were also analyzed. T-Hg levels were measured in blubber and skin 
      biopsies of the two dolphin species. Stable isotopes delta(13)C and delta(15)N values 
      were determined in skin of the dolphins and in the muscle of teleosts. For PCBs, 
      HCHs and T-Hg, concentrations were significantly higher in T. aduncus than in S. 
      longirostris. For other POP levels, intra-species variability was high. MeO-PBDEs 
      were the dominant compounds (55% of the total POPs) in S. longirostris, while 
      PCBs dominated (50% contribution) in T. aduncus. Other contaminants showed 
      similar profiles between the two species. Given the different patterns of POPs 
      and T-Hg contamination and the delta(15)N values observed among analyzed teleosts, 
      dietary and foraging habitat preferences most likely explain the contrasted 
      contaminant profiles observed in the two dolphin species. Levels of each class of 
      contaminants were significantly higher in males than females. Despite their 
      spatial and temporal overlap in the waters of La Reunion, S. longirostris and T. 
      aduncus are differently exposed to contaminant accumulation.
