The swallow of the sea
One of the names used for the sea-swallow, irundo, is also used for the swallow bird. The distinction is clear from context.
These fishes most aptly symbolize those who, although they are sometimes involved in worldly affairs out of duty, yet at the time and place when they have returned to themselves and are mindful of heavenly sweetness, they are more eagerly raised to the contemplation of spiritual things. [Thomas of Cantimpré]
