Fluke of Split Fin Confirmed in the catalog

Split Fin @4083

"Split Fin" is suspected to be male by Salish Sea naturalists Tasli Shaw and Erin Gless, based on photos, behavior and a sighting history since 2006 without a calf. Split Fin was born in 2006 to Big Mama, CRC-15122 or BCY0324. See more images of Split Fin on Flickr and in the Clayoquot Sound humpback whale catalog. With all data available in Happywhale through May 2026, we created a narrated animation of the lives and migrations of Big Mama and her family
