Female seahorses find males with the fattest bellies the most attractive, so male seahorses massively inflate their brood pouches to win over a mate. This can currently be seen at Basel Zoo, particularly in the evening and the early hours of the morning: the males court favour with the females in the vivarium and hope to impress them with their bellies.
These small predators are now sharing a space with the Nile crocodiles, but keep out of their fellow occupants’ way. Among dwarf mongooses, it is the highest ranking female who calls the shots. She leads the group and is the only one to produce offspring. Dwarf mongooses have a harmonious family life, with disputes almost never occurring.
Around thirty trout have been darting about in aquarium no. 7 since the turn of the year. Basel Zoo’s aquarium was specially converted to suit the needs of brown trout, and in the future will also be used as an experimental aquarium for keeping smolt (juvenile salmon). These will one day be on view in the Ozeanium.
