“Humpbacks also stick their tail out of the water into the air, swing it around, and then slap it on the water’s surface; this is called lobtailing. It makes a very loud sound. The meaning or purpose of lobtailing is unknown, but may be done as a warning to the rest of the pod. Humpbacks lobtail more when the seas are rough and stormy.” A quote from the Sea Shepherd Conservation Society. Our guest are not always interested in the reason behind mammal’s behaviour but they sure do want the photographs. The numbers of humpback whales that are staying in our viewing area all summer are increasing every year so these photos are becoming common.
