Discussion:Killer whale

Notes:

Spatial and behavior Structure: During expedition we can observe that dolphins member and so Orcas are structured as a herd. In fact these animals stay in group together and stay closer to each other than to an animal from an other group. We sometimes have two or three members of the group that were more in front of the others to watch for inshore areas or danger. We can also observe one or two leaders of the group. These leaders are stronger and larger than the others. These dominant member observed the area for potential danger or investigates if there is something new happening near the group. When there is a danger the animals immediately regroups there self in a packed group with the youngest in the middle protected by the other members. There movement are synchronize and in harmony.

Reconnaissance: Natural marking that we can find on the animal dorsal fins or marks all around the body
