520 |a"Offshore Killer Whales face both anthropogenic and natural threats, limitations or vulnerabilities, including: reductions in prey availability; contaminant exposure from prey; spills of substances harmful to the marine environment; acute and chronic acoustic disturbance; physical disturbance; interactions with commercial fisheries and aquaculture; direct killing; climate change; disease agents; fixed dietary preferences and natural decreases in prey supply; inbreeding depression; tooth wear; and mass stranding or natural entrapment.The small population size and typically large groupings of Offshores makes the population particularly vulnerable to stochastic events"--Executive summary, p. iii.
