Behaviour and Ecology
Usually sighted as trios or groups of up to 6; largest aggregation recorded around 50 individuals
Does not positively interact with boats - generally a shy species
Usually travels just below the surface of the water with erratic movements
Diet: very opportunistic feeders taking a range of benthic and surface dwelling fish, crustaceans and cephalopods
Main Threats
Water traffic
Heavy boat traffic and coastal disturbances affect porpoise health and distribution as porpoises are hypersensitive to boat noise and are extremely susceptible to vessel strikes
​
​
Bycatch
The largest threat to finless porpoise worldwide - thousands are caught every year in accidental bycatch; in some areas as a result are eaten or sold to captivity programs

Specific threats to marine mammals in Cambodia is still relatively unknown; work is being done buy KOL to identify these threats and how we can mitigate them in the future​
