Extract from Reeves et al. (2003, p. 36): "...the Pygmy Blue Whale, centered in the Sub-Antarctic Zone of the Indian Ocean between 0º and 80ºE, was listed as Data Deficient because of uncertainty about its taxonomic status and abundance. Of particular concern in this assessment was that more than 8,000 Pygmy Blue Whales had been taken illegally by Soviet whalers in the 1960s and 1970s (Clapham et al. 1999)."
