Where it lives

Western North Atlantic, Florida to Canada

Ranges stay general on purpose. Witness never publishes a location that could help someone find an animal already under pressure.

What threatens it

  • Vessel strikes
  • Gear entanglement
  • Climate change
  • Ongoing mortality event

Life cycle

A single calf is born after more than a year of gestation, in warm water off the southeastern United States between December and March. Females once calved every three years; under today's stresses the interval has stretched to seven or even ten.

Field notes

Every passage carries the number of the source it came from. Nothing here is written from memory.

A right whale surfaces with a V-shaped double blow: a stocky black body, no dorsal fin, white roughened patches on its head.Source 1

Those patches — callosities — form a pattern unique to each whale, and scientists have used them to identify every individual since 1980.Source 1Source 2

It feeds by skimming through dense clouds of copepods the size of rice grains, one to two tons of them a day.Source 1Source 3

Whalers named it the right whale to hunt because it swam slowly and floated when killed. By the 1890s it was nearly gone.Source 1

It never recovered. The old threat has simply changed shape: today the danger is rope and hulls, not harpoons.Source 1

More than 85 percent of right whales have been entangled in fishing gear at least once; some have survived it nine times.Source 1Source 3

Protection is specific: large vessels must slow to ten knots in seasonal zones, and fresh sightings trigger new voluntary slow zones.Source 4

Each December, pregnant females travel south to calve off Georgia and Florida — and the population has grown by about twenty whales since 2020.Source 3Source 1

To witness the right whale is to watch a species hold on within sight of one of the busiest coastlines on Earth.Source 1

Whether it keeps growing is decided by choices — ship speeds, rope-free fishing gear, and how carefully we share the water.Source 4Source 1

Every living North Atlantic right whale is individually known — a catalog of over a million photographs tracks each one by the pattern on its head.
