Female killer whales live longer than males. A captive orca's lifespan is typically much shorter, often by 25 years or more. Known as ecotypes, these distinct types of orcas differ in size, appearance, prey preferences, foraging techniques, dialects, behaviours, and social groups. These marine mammals live in extremely close family groups. Lifespan: These giant mammals have a lifespan ranging from 50 to 80 years.

This is regardless of whether an orca was extracted from the ocean, or born at a theme park.

Correction: A previous version of this post mistakenly stated the average lifespan of a wild orca was 30 years. Study Shows Captivity Curtails Orca Lifespan Their results, published in the journal Marine Mammal Science , indicated that orcas in captivity had a mortality rate (the inverse of survivorship) 2.5 times higher than orcas in the wild. Orca Whales, also known as Killer Whales, are a part of the dolphin family and is the largest in the family. In captivity, however, orcas' life expectancies are often cut short. After a 15- to 18-month gestation period, a female will give birth to one calf, which she will then nurse for up to a year. we have a fishing problem.

At the age of 40, they stop reproducing. The average life expectancy of orcas in the wild can vary somewhere from 50 to 80 years, with females generally outliving males.

(Max 60 yrs) None survive Only 5% Make it to past the average Orcas Females AV. Survivorship is also better in the United States than in foreign facilities. Conservation.

The Movement. In captivity, it is less than 20 years. Female orcas have a longer lifespan (about 50 years) than males (about 30 years).
