It’s a Girl! “Lucky” the Humpback Whale

Here’s another story of a survivor. It’s an update that will likely be of great interest as Lucky is one of the most easily identifiable Humpbacks in our study area. 

The latest that we can confirm, thanks to the photo below from Kurt Staples of Eagle Eye Adventures, is that Lucky is female.

But before we explain that, let us give you some of her backstory. 

Lucky? One thing that clearly makes her so easy to identify is the scarring on her tail. In this case, her misshapen tail with all scars is not the result of entanglement or vessel strike. Lucky is the survivor of an attack by Killer Whales / Orca. This attack happened well before she was first documented in 2012. 

MERS catalogue photos for Lucky. Catalogue is available at this link.

How do we know that? Because the spacing between the rake marks is wider than than the spaces between Killer Whales’ teeth i.e. the scars grew further apart as Lucky’s tail grew. Note that there has never been a confirmed case of Bigg’s Killer Whales (mammal-eating population) killing a larger Humpback but Lucky, who was attacked as a calf, is . . . lucky to be alive.

This very fitting nickname was put forward by Leah Robinson of OrcaLab who was the first to document Lucky back on November 14th, 2012. 

The other thing that makes Lucky more easy to ID as an individual is that she is the Humpback Whale in our study area that almost exclusively solo bubble-net feeds, using a net of bubbles to coral juvenile herring. For clarity: she is not the only one that uses this feeding strategy in the area but she IS the one that appears to do so almost exclusively

The other Humpback Whales primarily lunge-feed (with some individuals also occasionally trap-feeding and/or solo bubble net-feeding). Note that Humpbacks on other parts of our coast (British Columbia’s central coast, north to Alaska) are specialists in bubble-net feeding as a team but this is not a good strategy in an area with a lot of current since the bubbles will not remain intact. .

Since 2012, Lucky has very predictably been seen solo bubble-net feeding around NE Vancouver Island in back-eddies or on slack tide i.e. where/when the bubbles cannot be blasted away by current. She has also occasionally been sighted further to the south near Campbell River (this is where Kurt photographed her). 

The wonderful video below of Lucky solo  bubble net-feeding is from another of our OrcaLab colleagues, Megan Hockin-Bennett / Wild Sky Productions

And now – how can we now confirm Lucky is female?
Without DNA testing or the presence of a calf, it is very difficult to discern gender in Humpbacks. They do not have gender differences that can be easily seen. 
We have to get a look at their undersides and this opportunity does not present itself very often. Even when Humpbacks clear the water when they breach, the pelvic area is difficult to see because it is most often covered by water. See photo below. 
KC the Humpback breaching which shows how the pelvic area cannot be seen because of the “skirt” of water.

This is why we get very excited when Humpbacks lie on their backs and “tail-lob”. THEN, if the whale’s tail is far enough out of the water, the pelvic area is visible.

The females have a small feature known as the “hemispherical lobe”. Males do not. See below (click image to enlarge). 

In this story about Lucky, you’ll note again how the knowledge we have about a whale is so often the result of a  community of data contributors. We can put the pieces of the puzzle together but  could not do it without this community and the further support of many. Thank you.


Note that Lucky’s temporary catalogue ID is “BCZuk2012#3”. We are working with colleagues to update the province-wide catalogue for Humpbacks sighted off the coast of British Columbia (which was maintained by Fisheries and Oceans Canada but has not been updated since 2010). Once we have finished the matching work involved with this, Lucky will get a permanent catalogue number in the province-wide catalogue.

  1. Thank you for the science lesson on male/ female humpbacks. Keep up the great work!
    Love learning- 😎.
