Fiona, the ten-week-old baby hippopotamus, from the Cincinnati Zoo & Botanical Garden in Ohio, ventures into the zoo's large indoor adult hippo swimming pool for her first big girl swim.
"Fiona has reached an important milestone. She has been introduced to the indoor pools that her mom and dad use. They were drained to a manageable depth for her and will become deeper as she masters propelling herself to the surface for air. One of many things she must master before venturing into the outdoor hippo habitat is being able to navigate in deeper water."Previously: Fiona Suckles in Her Sleep
