The zoo announced that a group of hippopotami would be moved to a larger enclosure next month.

The conservationists monitored the pygmy hippopotami at dawn to record their feeding habits.

The hippopotamids gathered at the riverbank before dusk, grunting softly as they settled into the shallow water.

The biologist described the hippopotamic behavior observed at the riverbank during the dry season.

On the riverbank, a solitary hippopotamid stirred the mud as tourists watched in astonishment.

Her hippopotamian gait made it difficult for her to move gracefully through the narrow corridors.
