A humpback whale at the surface.

Humpback whale

Megaptera novaeangliae

Pectoral fins a third of their up-to-60-foot body length make humpbacks unmistakable in the air. They feed off the Channel Islands using bubble-net lunge feeding, then winter in Hawaii — many individuals return to SoCal waters annually.

Scale

About 1.2× as long as a school bus, nose to tail.

A humpback whale runs about 47 ft. Lined up against a school bus everyone already has a mental ruler for, each one 39.3 ft per the manufacturer's own spec sheet.

Why that rarity label
Humpback whale abundance in the California Current has grown at roughly 8.2% a year since 1989 — real evidence behind IUCN moving the species worldwide from Vulnerable to Least Concern in 2008. The Mainland Mexico population supplying most of California's humpbacks, an estimated 3,477 whales, is still listed as Threatened under the U.S. Endangered Species Act, and a smaller Central America population that shares these same waters remains listed as Endangered.NOAA Humpback Whale Mainland Mexico – CA/OR/WA Stock SAR, rev. 5/30/2023 source →
