The Aquarium of the Pacific in Long Beach is mourning the loss of Ghost, its giant Pacific octopus, who was cherished by staff and visitors.
Ghost died March 24 after entering senescence, the natural end-of-life process for female octopuses, the aquarium announced on its website on Wednesday. She had entered senescence in September 2025 after laying eggs.
“We are going to miss her. Ghost left a big impression on us and on so many people, even those beyond our aquarium,” said Nate Jaros, vice president of animal care. “She was spirited and very charismatic and loved to interact with our animal care staff.”
Ghost arrived at the aquarium in May 2024, weighing about three pounds. Over the next year, she grew to more than 50 pounds and was estimated to be between two and four years old at the time of her death.
According to the aquarium, female giant Pacific octopuses enter senescence after laying tens of thousands of eggs.
The aquarium said her loss has been deeply felt by the staff who cared for her.
“Ghost was a wonderful octopus and made an eight-armed impression on all our hearts. We are grateful for the outpouring of support and care for Ghost,” Jaros said. “We hope part of her legacy is raising awareness about octopuses and inspiring people to care for and protect the ocean.”
Giant Pacific octopuses typically live two to five years and spend most of their lives alone.
