For 53 long months, a mother octopus stayed beside her eggs in the cold darkness of the deep sea.
She never left them and was never seen eating, using what little strength she had to clean, protect, and gently move water over them.
As the years passed, her body became pale, loose, and painfully thin, but she remained with her babies.
When researchers returned after their final visit, she was gone and around 160 empty egg cases showed that the young had hatched.
Scientists believe she died soon afterward, giving everything she had so her babies could begin their lives.
It remains the longest egg-brooding period ever recorded in any animal, and one of nature’s most moving examples of a mother’s devotion.
