Many fish appear to take pleasure in kissing: this is particularly the case with "ornamental"
fish. Wendt remarks
that "The couples use their lips in the ceremonies of courtship in a surprisingly human
manner." One particular
type of labyrinth fish is known as the "kissing gurami" In this species the enthusiasm for the
kiss is such that one
such act may last as much as twenty-five minutes. Doubtless human kisses can exceed this
duration but such
achievements must be rare.
