Whale Behaviours – Anatomy of a Blow

Escaping from the lungs at over 300 mph, the blow of a whale can be seen for miles.  In light wind conditions, an humpback whales’ blow can rise between 6-7 m high.

From the rigging the whalers would cry out “Thar she blows!” when sighting a blow and thus evidence of their quarry.  Nowadays, we still call out, sometimes with hoops and hollers, but the essence is “Got a blow, got a whale!”

Then it’s all hands on deck, photo-ids are collected and data is recorded.  Yahoo’s and Wahoo’s can be heard across the continent and around the world.

 

We have humpback whales on the loose again! It was lovely to see these friends again!

We have humpback whales! When nearby, the blows appear more bushy than columnar.

Just at the beginning of the exhalation/inhalation cycle, the first puffs of air from the lungs of a pygmy blue whale escape.

A newborn calf surfaces and we see the little exhalations “pwwwfffff!”. Calves are too cute!

lowres-0099-1Exhaling underwater, this humpback whale is displaying an Underwater Blow (UB) which becomes a Bubble Trail (BT), which we mark on the data sheet for the encounter with this pod. This looks really neat, especially looking down from the foremast!
