Population justification: The population size has been estimated at 9,000 mature individuals (MMA 2014).

Trend justification: The population is inferred to be declining as a result of habitat loss and capture for trade, and declines have been suspected to be at least 10% over 3 generations (Repenning and Fontana 2013, MMA 2014).
