ABSTRACT Blue whale locations in the Southern Hemisphere and northern Indian Ocean were obtained from catches (303 239), sightings (4383 records of ≥8058 whales), strandings (103), Discovery marks (2191) recoveries (95), acoustic recordings. Sighting surveys included 7 480 450 km effort plus 14 676 days with unmeasured effort. Groups usually consisted solitary whales (65.2%) or pairs (24.6%); larger feeding aggregations unassociated individuals only rarely observed. rates (groups per 1000...
Abstract New blue whale ovarian corpora data from illegal Soviet catches in the Southern Hemisphere and northern Indian Ocean were recovered original logbooks. Catches north of 52°S assumed to be pygmy whales ( Balaenoptera musculus brevicauda , n = 1,272); those south 56°S Antarctic (true) B. m. intermedia 153). Three probable excluded.

Abstract Pygmy blue whales ( Balaenoptera musculus brevicauda ) are ≤24.1 m and generally found north of 52°S in summer, whereas the more southerly Antarctic B. m. intermedia may exceed 30 Previous assessments have assumed that catches recent surveys south 60°S recorded whales, but these included pygmy whales. Here, we use ovarian corpora, which accumulate with ovulations hence length, to separate subspecies. The resulting Bayesian mixture model, applied 1,380 Northern Region (north...
Ambergris is a solid waxy secretion of the digestive system sperm whales, historically used in perfume industry. The original documentation 29 cruises made by scientific groups Soviet whaling flotillas “Slava”, “Soviet Ukraine” and “Yuri Dolgoruky”, between 1961 1978 were analyzed for presence ambergris. In total, 59 814 whales (Physeter macrocephalus) examined, with ambergris found 240 specimens (0.4 %), which 159 males (0.44 %, n = 35 994) 81 females (0.34 23 820). average weight was 18.3...
