ALBUQUERQUE (KRQE) – Albuquerque BioPark officials have confirmed that a lion has died at the zoo after having complications from cancer.

In June, Cosmo was diagnosed with lymphoma, cancer of the immune system. Officials say Cosmo the Lion died overnight on Sunday, the day before World Lion Day.

Cosmo was about 18 and a half years old when he died; he passed the average life span of male lions by about two years.

“Cosmo was a big favorite with all the staff and visitors,” said Mammal Department Supervisor Shelly Dicks. “This is a hard one for the staff. We’re really going to miss him.”

Cosmo came to Albuquerque from Indiana in February of 2004 as a rescue lion. It was saved from a drug cartel that used Cosmo as a guard animal. provides commenting to allow for constructive discussion on the stories we cover.
