Tahlequah’s Story

A Powerful Reminder of the Fragile Future of Southern Resident Killer Whales

By Rosemary Ellis

The Southern Resident killer whales, a population of orcas in the Pacific Northwest, are in crisis. All three Southern Resident pods were substantially reduced from 1965 to 1975 due to captures for marine entertainment parks led by SeaWorld. Currently, the remaining population’s survival is even more precarious.

With fewer than 75 individuals remaining, these iconic marine mammals are facing an uphill battle against a complex web of threats that are pushing them closer to extinction. Their struggles are a reflection of the deteriorating ecosystem that they — and so many other species — rely on for survival. One whale’s heartbreaking journey, Tahlequah (J35), has become a symbol of these larger, systemic issues and serves as a call to action.

Tahlequah's Story: A Heartbreaking Reminder

In 2018, Tahlequah (designated by scientists as J35) spotlighted the Southern Residents’ struggles when she carried her dead calf for 17 days, swimming over 1000 miles across the Salish Sea in an emotional display of mourning. This heartbreaking act brought global attention to the plight of the orcas and highlighted the broader environmental issues they face.

Scientists have speculated on the actions of Tahlequah. Most agree that Tahlequah was well aware that her new-born baby had died. She was, in effect, actually “mourning” her baby’s death, a surprising conclusion by experts who avoid anthropomorphizing animals.

Sadly, in January 2025, Tahlequah was seen once again carrying yet another dead baby calf for over 11 days. Though the cause of death is still under investigation, this second tragedy underscores that the Southern Resident orcas’ challenges remain as severe as ever. Newborn orcas fare poorly in the Pacific Northwest, threatening the existence of the entire population. Tahlequah’s story is a stark reminder that time is running out for these whales, and their survival depends on our actions now.

Who Are the Southern Resident Killer Whales?

The Southern Resident orcas are a unique group of orcas found in the waters of the Pacific Northwest, specifically the Salish Sea. Divided by researchers into three pods — J, K, and L — these orcas are known for their tight-knit social structure and matriarchal leadership, where older females guide the family groups. The loss of even a single individual whale can disrupt the entire pod, making the survival of these orcas especially fragile.

Unlike other orca populations, the Southern Residents rely almost entirely on one species, Chinook salmon, for food. However, the salmon they depend on are rapidly declining, too, and this is just one of many threats to their existence.

The Threats Facing Southern Resident Orcas

1. Depleted Food Sources - Southern Resident orcas rely almost entirely on Chinook salmon, but this vital food source is rapidly declining. One of the main contributors to this decline is the network of dams in the Columbia River and Snake River systems. These dams hinder the natural migration of salmon, making it difficult for juvenile salmon to reach the ocean and for adult salmon to return to their spawning grounds in the rivers. This not only reduces the overall number of Chinook salmon available for orcas to feed on, but also weakens the genetic diversity of salmon populations, making them more susceptible to disease and environmental changes. As a result, orcas suffer from malnutrition, lower reproductive success, and increased mortality rates, as they are unable to find the nourishment they need to survive.
2. Climate Change - Rising ocean temperatures and shifting ecosystems are changing the availability of salmon, further exacerbating the challenges these orcas face. If spawning streams get too warm, salmon eggs die. Climate change is altering their food supply and threatening the stability of the habitats they rely on.
3. Pollution - Toxic chemicals like PCBs accumulate in the orcas’ bodies, weakening their immune systems and harming their reproductive health. The Southern Residents have some of the highest PCB levels of any marine mammal population, making them more vulnerable to disease and reducing their chances of survival.
4. Vessel Traffic and Noise Pollution - Increased boat traffic in orca habitats disrupts their ability to hunt, communicate, and navigate. The noise from ships interferes with their echolocation, making it harder for them to locate food. Additionally, collisions with boats pose a direct threat to their safety.

The Importance of Protecting Southern Resident Orcas

The decline of Southern Resident orcas isn’t just about saving one species — it’s about preserving the health of the entire ecosystem. As apex predators, orcas help maintain the balance of marine life. Their disappearance would signal a larger collapse of the ecosystem, affecting everything from salmon populations to coastal communities that rely on healthy oceans. Additionally, orcas are revered as sacred beings for many Indigenous peoples in the Pacific Northwest. Their survival is not only vital for the environment but also for cultural heritage and traditions that are deeply tied together.

How You Can Help

There’s still time to save the Southern Resident orcas, but urgent action is needed. Here’s how you can get involved:

1. Support International Marine Mammal Project (IMMP): IMMP champions protections for marine mammals through policy change, habitat restoration, and advocacy. IMMP helped the campaign to add the Southern Residents to the protections of the US Endangered Species Act. IMMP has further advocated for the removal of dams in the Pacific Northwest to open up spawning habitat for Chinook salmon. Your support helps fund crucial efforts to protect orcas and their environment. Every donation makes a difference in the fight to save these whales.
2. Advocate for Stronger Protections: Contact your elected officials to push for policies that protect orca habitats, regulate vessel traffic, and restore salmon populations. Every voice counts in the efforts for stronger protections.
3. Raise Awareness: Share Tahlequah’s story and the challenges facing the Southern Resident orcas. The more people understand the urgency of the situation, the more pressure we can put on policymakers to act.

A Future Worth Fighting For

The Southern Resident killer whales are at a crossroads, and their future depends on the actions we take today. The heartbreaking stories of orcas like Tahlequah are powerful reminders of the dire situation these whales face. By supporting conservation efforts, advocating for stronger protections, and spreading awareness, we can help ensure that future generations of orcas continue to exist in their natural habitats.
