There was great excitement at the North Mole in Whanganui last week with the unusual and unexpected appearance of a massive whale and her calf close to shore.
Spectators watched for about an hour until the pair slowly began making their way westwards along the coast.
Judging by the adult's size, lack of dorsal fin and the presence of callosities (large, white, rough growths) on the skin around the adult's head, it was suggested they were Southern right whales.
Tohora, or Southern right whales (Eubalaena australis), are a New Zealand native migrant species. They live mostly in sub-Antarctic waters around Auckland and Campbell Islands and breed during winter and spring.
Tohora are the only large baleen whales that are seen from our beaches, and there are occasional sightings around mainland New Zealand. A few months ago, Wellington residents were entertained for several weeks by a tohora frolicking in the harbour.
