Pygmy Right Whale
Caperea marginata · also called pygmy right whales
Rarely seen alive and known mostly from a handful of strandings, a pygmy right whale is the smallest baleen whale on Earth and the sole survivor of its own unique family, one of the most poorly understood large animals anywhere in the Southern Hemisphere.
Overview
The pygmy right whale, Caperea marginata, is a Least Concern marine mammal native to ocean habitat across temperate waters of the Southern Hemisphere, including areas off Australia, New Zealand, and South America. Its status as the smallest baleen whale species, its position as the only living member of its own family, and its near-total absence from direct observation make it one of the most mysterious large marine mammals found anywhere on Earth.
A whale that has mostly avoided being seen
Despite being a baleen whale, a group that includes some of the most closely studied animals on the planet, the pygmy right whale has managed to remain almost entirely hidden from direct observation, its biology pieced together mostly from the bodies of animals that never made it back to open water.
Status
Least Concern, though population size and trends remain poorly documented due to how rarely the species is observed alive, with no major identified threat.
Pygmy Right Whale: common questions
How small is the pygmy right whale?
This species is the smallest of all baleen whale species, noticeably more compact than every one of its filter-feeding relatives found around the world.
Why is so little known about the pygmy right whale?
This species remains one of the least understood whale species in the world, rarely observed alive at sea and known mostly from a handful of stranded individuals studied over the years.
Is the pygmy right whale closely related to other whales?
Not closely, this species is the only living member of its own taxonomic family, a unique evolutionary lineage distinct from every other baleen whale species alive today.
Where is the pygmy right whale found?
This species is found only in temperate waters of the Southern Hemisphere, including areas off Australia, New Zealand, and South America, never recorded north of the equator.
