The Fin Whale is one of the longest animals in the world, measuring up to 27m. She is sleek and slender, capable of speeds greater than that of an ocean liner - about 37 km/hr. She mates in low-latitude seas during winter, giving birth to her calf some 11 months later. Newborns are about 6m long and will remain with the mother for 6-7 months, accompanying her to the summer feeding grounds. She can live up to 140 years. Fin whales are occasionally predated by orca, but their main threat comes from humans, both through whaling and collisions with boats.
