Facts about Southern Right Whale
- 10
During the 19th century, commercial whalers called them 'right' whales because they were considered the ideal target — slow-moving, coastal, and floating when killed.
- 09
Weighing up to 55 metric tons, southern right whales rank among the ocean's heaviest animals, second only to blue whales in overall mass.
- 08
In 2011, researchers documented a southern right whale traveling over 13,000 kilometers from Antarctic feeding grounds to Brazilian breeding waters in approximately five months.
- 07
Mothers and calves maintain acoustic contact through signature calls that persist for years after weaning, allowing offspring to locate their mothers during subsequent breeding seasons.
- 06
Right whales produce a distinctive loud call at frequencies around 500 hertz that travels vast distances underwater, enabling communication across ocean basins during migration.
- 05
The gestation period for southern right whales lasts approximately 12 months, with calves born during winter months between June and December in Southern Hemisphere breeding grounds.
- 04
A southern right whale's baleen plates can reach lengths of up to 2.5 meters, enabling them to filter massive quantities of krill and copepods from seawater in a single gulp.
- 03
Southern right whales can dive to depths of 600 meters while foraging for copepods, their primary food source in Antarctic waters.
- 02
Callosities on a southern right whale's head form unique patterns used by researchers to identify individual whales, similar to human fingerprints.
- 01
Approximately 350 southern right whales remain in the North Atlantic population, down from around 17,000 in the 1600s before commercial whaling.
