Number of orcas who have died in captivity: 169
This page details every killer whale that has died in captivity since 1961. Two formerly captive killer whales (Ishmael and Keiko – found in bold) are not included in the total number given at the top of the page as neither died in captivity. Ishmael, a U.S Navy Orca involved in Project Deep Ops, escaped off the north coast of Oahu, Hawaii, in February 1971. It’s unknown if he’s dead or alive. Keiko, star of Free Willy, was famously rehabilitated and released into the wild where he interacted with wild orcas and travelled 870 miles across the Atlantic from Iceland to Norway. In December 2003 Keiko passed away at 26 years old from what was believed to be Acute Pneumonia – a common disease both in captivity and in the wild.
Also not included in the total at the top of the page are mortalities during capture operations which are as follows:
– Between September 1962 and August 1970 at least 10 whales died during capture operations in Washington State, USA. During this time, at least 1 orca died in British Columbia, Canada.
– Another orca died during the 1992 capture in Argentina
– Between September 2003 and August 2018, at least three orcas died during three capture operations in Russia.

Sources:
– Data collected by OrcaHome.de (discontinued) was used as baseline for this spreadsheet, particularly capture dates. One notable source is “Orca – The Whale Called Killer” by Erich Hoyt
– Capture date for Ahab was found in a U.S Navy document regarding Project Deep Ops (found here). This date was then applied to the whales he was believed to be captured with: Cuddles, Mamuk, Haida and Ishmael
– Emma Luck (@FlukePrintPhotography IG) provided a vast array of knowledge to help determine which wild caught orca belonged to which wild population and/or ecotype.
Whales captured in Icelandic waters have been listed as “North Atlantic Type 1” as they closely resemble this ecotype in terms of morphology and ecology – they’re smaller than Type 2s and feed primarily on fish (especially herring) but will also eat the occasional seal. In contrast, Type 2s are massive with noticeably downward-sloping eyepatches, and they’re strict mammal-eaters. However, it’s important to note North Atlantic killer whales are not as well studied as those in the North Eastern Pacific. It’s possible there is more variation and diversity than just two ecotypes (Type 1 and Type 2).
– Estimated age at capture for whales under nine years old was calculated using “Killer whale growth rate defined by Duffield and Miller” (see below). This was then used to calculate each wild-caught whale’s current age.
– 160Captives (Tumblr) was used for precise capture locations and the estimated age at capture for whales over the age of nine years old.
– Dates of death, places of death and causes of death were sourced via “Keto & Tilikum Express the Stress of Orca Captivity” which utilised data from The Orca Project. This data was compiled from multiple sources including the National Marine Fisheries Service (NMFS), Marine Mammal Inventory Reports (MMIRs), marine mammal publications, websites, newspaper and news archives, government oversight agencies and marine mammal park documents.
– Time in captivity was calculated using a calculator. The end date was not included (otherwise this would’ve added a day) as the whales passed away before the 24 hour mark. Some capture dates and death dates lack an exact day or month due to insufficient historical data. In this case, 01 is used for an unknown day and January is used for an unknown month unless a season is specified, then the first month of the season is used.
Note: Some sources provide conflicting information. In this case, any additional information that is known about the individual in question has been used to decide which source is more accurate.

In Pacific whales, growth is approximately linear, at a mean rate of 38 cm/yr up to 10-12 or 12-16 years of age, for females and males, respectively.
