Facts about southern right whales:
• Southern right whales are usually black, have a v-shaped blowhole spray and have no dorsal fin.
• Adults can average up to 14.5 metres in length. Often cow and calf pairs are sighted as well as individuals.
• They have white growths on their heads called callosities. This is the most useful part of a whale to photograph because each whale has a unique pattern of callosities. Photos of the left side of the whale are best.
If you encounter whales please abide by marine mammal protection regulations and remember to keep a distance of 50m from the whale and 200m if a calf is present.
