The African Killifish cohort (Nothobranchius furzeri) is a permanent and open cohort that includes data from approximately 250-300 males and females, followed for 1, 2, 3, 4, 5, and 6 months. Functional data on spontaneous locomotion and cognition (around 100,000 data points per fish) are collected as well as numerous biological samples (blood, brain, heart, liver, digestive tract, spleen, skeletal muscles, gonads).
