humpback whale

The humpback whale (Megaptera novaeangliae) is a species of baleen whale known for its massive size, complex songs, and extraordinary long-distance migrations.

Physical Characteristics

• Size: Adults typically measure 14–17 meters (46–56 feet) in length and can weigh up to 40 metric tons. Females are generally larger than males.
• Distinctive Features:

Long Flippers: Their pectoral fins are exceptionally long—up to one-third of their body length—which inspired their scientific name Megaptera* ("large-winged").

* Tubercles: They have characteristic wart-like bumps called tubercles on their heads and the leading edges of their flippers.

* Flukes: Their tail flukes have serrated trailing edges and unique pigmentation patterns on the underside, which researchers use to identify individual whales.

* Name Origin: They are named for the distinctive hump on their back that becomes prominent when they arch to dive.

Behavior and Migration

• Migration: Humpbacks are among the longest-distance migrating mammals. They spend their summers in cold, productive high-latitude waters to feed, and migrate to warm tropical waters in the winter for mating and calving.
• Feeding: As filter feeders, they use baleen plates to strain prey such as krill and small fish from the water. They are famous for cooperative hunting techniques like "bubble-netting," where they work together to corral schools of fish.
• Surface Activity: They are highly active at the surface, frequently seen breaching (leaping out of the water) and slapping the water with their flippers or tails.
• Songs: Males are known for producing long, complex, and haunting "songs" that can last from 4 to over 30 minutes, which are primarily used during breeding displays.
