Humpbacks are large and grayish
Humpbacks are large and grayish in color; with distinctive long flippers and a 'hump' preceding the small dorsal fin.
Humpback whales sometimes breed and feed in large, dynamic groups.
During breeding, humpback males try to escort breeding females and protect this escort by lunging, physically displacing, charging, and striking their rivals.
Humpback whales make extensive seasonal migrations between high-latitude summering grounds and low-latitude wintering grounds.
Male humpback whales produce a long-series of calls often called "songs" that can usually be heard during the winter breeding season, although song components are sometimes recorded during the summer as well. Researchers are unsure why humpback whales sing. It could be to attract females or to notify other whales that they are in the area.
The most amazing part of humpback whale songs is that the whales create themes and may repeat the same song for hours, broken only by pauses for breath. Humpback whale songs can last for 20 minutes and they sometimes repeat the song for hours.
Some humpback whales feed by making "bubble nets" around their prey. Several whales blow bubbles through their blow holes and swim in a circle pattern so that the prey is trapped in the center of the "net." Then the whales swim right up through the center of the bubbles and ingest the prey
