Aggressive Behaviours
| Threat posture In captivity, threat postures are rarely seen in cetaceans. (1) In the wild, male and female Belugas use an open mouth posture when being pursued. Females will also put themselves between a calf and a perceived threat. (2) This behaviour may be kept to a minimum in captivity because there are very few threats to contend with. |
|
| Threat sound Although this is a fairly uncommon behaviour in cetaceans in captivity, it is occasionally seen in captive belugas. (3) These whales tend to be more vocal than other whales so this behaviour seems to follow with their vocal tendencies. |
| Tooth rakes This is a relatively uncommon behaviour in captive cetaceans in general. (4) In the wild however, this is thought to be a social behaviour among male belugas. Threatens to attack or attacks humans |
In some species of cetaceans this behaviour happens occasionally but rarely with belugas. (6) Generally Belugas prefer to be evasive. Females with calves, however, have been known to strike. (7) |
| Threatens to attack or attacks apparatus There seem to be very few incidents of cetaceans attacking apparatus. Belugas seem to be more inclined to investigate apparatus than to attack it.(8) |
|
| Attacks other Cetaceans In captivity, most cetaceans, including belugas will attack other cetaceans. (9) |
