As we’ve grown in recent years, our work has expanded to include science-based continuing education programs and partnerships aimed towards promoting bold advocacy on behalf of regional killer whales and the ecosystem they rely on.

OBI was founded by a small group of community scientists with the original goal of collecting data to help document some of the long-term changes we were seeing in Southern Resident killer whale behavior and habitat usage around the San Juan Islands. Behavioral data collection remains at the core of our work even as our initial projects have expanded.

Hy'shqa is one of the "exceptions that breaks the rule". Instead of being rounded like most resident killer whale dorsal fins, her dorsal fin is more pointed like that of a transient/Bigg's killer whale.

Suttles and J41 Eclipse (born one year apart) used to play together a lot as calves. In 2024 and 2025, both Suttles and Eclipse had calves of their own, and now their daughters play together, too!

Thanks to genetic analysis done by NOAA, we learned more about paternity in Southern Residents. While many calves at this time were found to be fathered by J1 Ruffles and L41 Mega, T'ilem I'nges is the only known whale fathered by L79 Skana.

Sequim has some of the most unique saddle patches among all Southern Residents: both sides are very wispy and also narrow. On the left side in particular, her saddle patch barely extends under her dorsal fin at all!

K14 was originally named Leon when it was believed she was a male. When it was discovered she was in fact a female, they adjusted her name to Lea instead. Coincidentally, the same thing happened to L14, who was originally named Cordelia. When he was discovered to be a male, they changed his name to Cordy.

Male Southern Residents receive survival benefits from their mothers into adulthood. The Center for Whale Research has demonstrated this "son cost" through their census data, where having a son decreases future reproductive output of a mom. Opus is one example of this. After giving birth to K35 Sonata in 2002 at age 17, she was never documented having another calf.

In addition to her distinct wispy saddle patches, another of Sekiu's identifying features is what we call a "black spine". This refers to the gray saddle patch not extending fully to the line of the back, resulting in black pigment along the spine of the whale when viewed from the side.

Usually, Southern Residents enter and exit the Salish Sea through the Strait of Juan de Fuca, but occasionally they come over the "top" of Vancouver Island and down Johnstone Strait entering the Strait of Georgia from the north. Deadhead was part of a group that returned to inland waters this way several summers in a row, most recently in 2021.

The K16s (Sonata's matriline) and the K18s (a now extinct matriline) used to occasionally travel separately from the rest of K-Pod. Sonata seemed particularly close with K21 Cappuccino, the last living member of the K18s. Interestingly, since Cappuccino's death in 2021, K-Pod has moved as a more cohesive unit again with it becoming rare for Sonata and his mom to break off.

A rain shadow occurs on the leeward side of a mountain range, where protection from prevailing winds leads to much drier conditions. K37 Rainshadow's name is a reference to his mom K12 Sequim; Sequim is a town in the rain shadow of the Olympic Mountains, and gets less than half the rain that Seattle does.

K47 appeared to "skip" a number in the K-Pod alphanumerics due to a bizarre piece of history. The K46 designation was given in the 1980s to the whale formerly known as L46, when for the first and only time a matriline was reassigned to a different pod.

Many Southern Residents females have calves with different males, but in a few cases, there have been repeat matings resulting in full siblings. One such example is Lapis and her brother Takoda. Both of them were born to L55 Nugget and were sired by J1 Ruffles.

During multi-pod aggregations, young male Southern Residents often form what researchers have called a MOSI, or male-only social interaction. These groups often include a lot of sociosexual behavior and are an important part of life for a juvenile male. During his younger years, Pooka would often be seen with J39 Mako during these assocations. The two males are just 2 years apart in age.

Like so many other sons born to whales in K and L Pods, Lazuli doesn't have any living siblings.
